- Oration I Against the Arians 56Athanasius of Alexandria · ca. 339–346 · Athanasius argues that “having become” in Heb 1:4 is joined to “better” and to the title Son, so it does not make the Son originated, and that making him of the angels' kind repeats Gnostic teaching.
- Oration II Against the Arians 19Athanasius of Alexandria · ca. 339–346 · The Arian formula “a creature, but not as one of the creatures” is a pretense: every creature differs from every other, so the phrase leaves the Son one creature among many.
- Oration II Against the Arians 28Athanasius of Alexandria · ca. 339–346 · Creatures share their tasks and need one another, which cannot be said of the Word; and Asterius's claim that the Son learned to create would make Wisdom something acquired and losable.
- Oration II Against the Arians 32Athanasius of Alexandria · ca. 339–346 · The Arians fight not with the church but with God's own testimony; Scripture's images of radiance and impress show the Word's eternity, and they suffice without prying into how.
- Oration II Against the Arians 33Athanasius of Alexandria · ca. 339–346 · A word from a mind and radiance from the sun are proper to their source, eternal with it, and do not divide it; so the Son is from the Father without division or beginning.

- Oration II Against the Arians 37Athanasius of Alexandria · ca. 339–346 · The Arians posit a second, true Word and Wisdom in God, making the Son only notionally Word and Wisdom; Athanasius quotes Asterius's argument from 1 Cor 1:24 and Rom 1:20.
- Oration II Against the Arians 38Athanasius of Alexandria · ca. 339–346 · If the Son were Word, Wisdom, and Son only in name, he would be nothing in himself; and an unoriginate Wisdom coexisting with God is either the Son or makes God composite.
- Oration II Against the Arians 40Athanasius of Alexandria · ca. 339–346 · The only unoriginate Wisdom coexisting with God is the Son; even Asterius, writing against pagans, confessed one Word and one Wisdom, contradicting himself.
- Oration II Against the Arians 42Athanasius of Alexandria · ca. 339–346 · Grace comes from the Father in the Son; those who deny the true Son, like the Jews who rejected him, endanger even baptism, which requires right faith together with the names.
- Oration II Against the Arians 43Athanasius of Alexandria · ca. 339–346 · Heretical baptism with the right names but wrong faith is profitless; the Arians, backed by human patronage, are worse than heresies that err about Christ's body, since they blaspheme the Father's own Godhead in the Son.
- Oration II Against the Arians 58Athanasius of Alexandria · ca. 339–346 · John's “was” excludes any interval before the Son; in Deut 32, Moses puts “made” before “begot,” showing that human beings are made by nature and only afterwards called begotten by grace.
- Oration II Against the Arians 70Athanasius of Alexandria · ca. 339–346 · Only if the Word is true God and his flesh truly human could humanity be freed and deified; Arians who deny the first are as wrong as Valentinians who deny the second.
- Oration III Against the Arians 2Athanasius of Alexandria · ca. 339–346 · Asterius explains John 14:10 as meaning only that Christ's words and works came from the Father; Athanasius replies that this makes the saying true of every prophet and saint.
- Oration III Against the Arians 7Athanasius of Alexandria · ca. 339–346 · Texts calling God “one” and “only” are not aimed at the Son, who is no rival to the Father but glorifies him; they are directed against the false gods made by human beings.
- Oration III Against the Arians 15Athanasius of Alexandria · ca. 339–346 · The sun-and-radiance image shows one principle, not three gods as Greeks charge; it is the Arians, with a created Son and Spirit, who fall into polytheism, while the church confesses one Godhead in the Trinity.
- Oration III Against the Arians 27Athanasius of Alexandria · ca. 339–346 · The Arians, stumbling at Christ's human experiences, repeat the objections of those who rejected him in the Gospels, and both deny the Word's Godhead because of his flesh.
- Oration III Against the Arians 55Athanasius of Alexandria · ca. 339–346 · The one who wept and hungered also raised Lazarus and gave sight to the blind; his sufferings show that the impassible God took passible flesh, and his works show that he is the Word.
- Oration III Against the Arians 59Athanasius of Alexandria · ca. 339–346 · Now the Arians say the Son came into being “by the Father's will”; Athanasius argues that this means the same as “there was when he was not,” and that Scripture speaks only of the Son's “being.”
- Oration III Against the Arians 60Athanasius of Alexandria · ca. 339–346 · Scripture speaks of will only for creatures; the idea of a will preceding the Word comes from the Valentinian Ptolemy, and Asterius's argument makes the Son one of the things made.
- Oration III Against the Arians 62Athanasius of Alexandria · ca. 339–346 · The Arian dilemma “by will or by necessity” ignores what is by nature, which is above both; as God is good by nature, not by choice or compulsion, so he is Father of the Son by nature.
- Oration IV Against the Arians 3Athanasius of Alexandria · 4th century (disputed) · The author argues that the Word must be from God himself, and so is distinct from the Father yet one with him, and warns against making the Word merely attached to God.

- Oration IV Against the Arians 11Athanasius of Alexandria · 4th century (disputed) · The author argues that those who say the Word was put forth for creation, like the Arians who say he was created for us, make the Word depend on us and God inactive before.
- Oration IV Against the Arians 17Athanasius of Alexandria · 4th century (disputed) · The author explains that in John 10:30–38 Jesus refutes both Sabellius and Arius, and that the sayings of unity with the Father are spoken by the Son.
- Oration IV Against the Arians 25Athanasius of Alexandria · 4th century (disputed) · The author rejects both Arius and Sabellius, and shows that the Sabellian image of one Father “broadened” into Son and Spirit makes the incarnation, baptism, and creation merely temporary.

- Defence against the Arians 58Athanasius of Alexandria · ca. 349–357 · Athanasius quotes the recantation of Ursacius and Valens to Julius, with their anathema of Arius, and their letter of peace to himself, and prepares to recount the affair from its beginning.

- On the Decrees of Nicaea 1Athanasius of Alexandria · ca. 350–356 · Athanasius praises his correspondent for refuting the Arians, who, like the Pharisees with Jesus, invent pretexts such as the complaint that Nicaea used unscriptural terms.
- On the Decrees of Nicaea 2Athanasius of Alexandria · ca. 350–356 · The Arians, like the Pharisees, cavil at the council’s wording instead of defending the views for which they were condemned.
- On the Decrees of Nicaea 3Athanasius of Alexandria · ca. 350–356 · The Arians at Nicaea were silenced, and Eusebius of Nicomedia’s party and even Eusebius of Caesarea signed the creed with “from the essence” and “of the same essence.”
- On the Decrees of Nicaea 5Athanasius of Alexandria · ca. 350–356 · From Moses back to Adam and on to Paul the teaching has been one, so the Arians must either condemn their leaders’ change of mind or accept the council.
- On the Decrees of Nicaea 6Athanasius of Alexandria · ca. 350–356 · Athanasius quotes the Arian claims that the Son is a creature, and asks in which of Scripture’s two senses of “son” they take him: by adoption for virtue, or by nature.
- On the Decrees of Nicaea 7Athanasius of Alexandria · ca. 350–356 · Athanasius refutes the Arian claim that the Son alone was made by God directly and everything else through him, showing that it leads to an infinite regress of mediators.
- On the Decrees of Nicaea 9Athanasius of Alexandria · ca. 350–356 · Even Adam, though formed by God’s hand, does not differ in nature from other men; so on Arian premises the Son would not differ from creatures.
- On the Decrees of Nicaea 10Athanasius of Alexandria · ca. 350–356 · If the Son were Son only by adoption he would differ from us only in degree; but he is Son by nature, though not with a human, bodily kind of generation.
- On the Decrees of Nicaea 13Athanasius of Alexandria · ca. 350–356 · The Arians appeal to Prov 8:22, “The Lord created me,” but Scripture distinguishes making a creature, like a house, from begetting a son.
- On the Decrees of Nicaea 15Athanasius of Alexandria · ca. 350–356 · Since Scripture calls the Son God’s Word and Wisdom, saying he once was not means saying God was once without Word and Wisdom.
- On the Decrees of Nicaea 19Athanasius of Alexandria · ca. 350–356 · The council wrote “from the essence” because the Arians claimed that “from God” applied to all creatures alike.
- On the Decrees of Nicaea 20Athanasius of Alexandria · ca. 350–356 · Because the Arians claimed that “like,” “always,” “power,” and “in him” applied to us too, the council wrote “of the same essence” and added its anathemas.
- On the Decrees of Nicaea 28Athanasius of Alexandria · ca. 350–356 · The Arians borrowed the non-scriptural term “unoriginate” from the Greek philosophers to reintroduce their condemned claims about the Son.
- On the Decrees of Nicaea 29Athanasius of Alexandria · ca. 350–356 · Even in the sense “without cause of being,” calling God unoriginate names him in relation to his works, not to the Son, as a builder is maker of houses but father of his son.

- Against Eunomius 1.4Basil of Caesarea · ca. 364 · Basil exposes how Eunomius praises the Fathers' creed and then 'corrects' it, mocks his proof that God is unbegotten, argues that 'Father' is the better name, and begins his account of conceptualization (epinoia).
- Against Eunomius 1.8Basil of Caesarea · ca. 364 · Basil exposes Eunomius's claim that calling 'unbegotten' God's essence is a debt of piety, showing that the same logic would make every divine name mean the same thing and would apply equally to the Son.
- Against Eunomius 1.9Basil of Caesarea · ca. 364 · Basil traces Eunomius's argument about privation to Aristotle's Categories and shows that 'unbegotten' belongs with 'incorruptible,' 'invisible,' and 'immortal,' so that his reasoning would prove too much.

- Against Eunomius 1.23Basil of Caesarea · ca. 364 · Basil argues that since the Son, like the Father, is incorporeal and formless, it is pious to compare them.
- Against Eunomius 1.24Basil of Caesarea · ca. 364 · Basil argues that the Jews drew the right inference that calling God Father means equality, and shows that Eunomius's view of 'Father' as an activity contradicts his claim that the Father is greater.
- Against Eunomius 1.26Basil of Caesarea · ca. 364 · Basil exposes the contradiction of calling the Father both 'greater' and 'incomparable,' and argues that belittling the Son removes the knowledge of the Father himself.
- Against Eunomius 1.27Basil of Caesarea · ca. 364 · Basil concludes Book 1: if the Father is incomparable, the Son would be no different from creatures, contrary to his words 'I and the Father are one,' and Eunomius's argument refutes itself.

- Against Eunomius 2.2Basil of Caesarea · ca. 364 · Basil denies that any saint called the Son a 'thing made,' and argues that Acts 2:36 ('God made him Lord and Christ') speaks of the incarnate Christ's authority, not of his coming into being.
- Against Eunomius 2.4Basil of Caesarea · ca. 364 · Basil argues from the names Peter and Paul that names signify distinctive features, not essences, so a difference of names cannot prove a difference of essence between Father and Son.
- Against Eunomius 2.6Basil of Caesarea · ca. 364 · Basil exposes Eunomius's selective concern about bodily notions of begetting, and argues that 'offspring' is a name never given to the Son in Scripture, which uses 'Son', as the Septuagint translators kept even Hebrew names untranslated out of reverence.
- Against Eunomius 2.8Basil of Caesarea · ca. 364 · Basil argues that Scripture calls the Lord 'Son' but never 'offspring,' a word used of unformed miscarriages, crops, and the 'offspring of vipers.'

- Against Eunomius 2.10Basil of Caesarea · ca. 364 · Basil shows that if 'offspring' named an essence, all offspring would share one essence and the Son would be the essence of the Father himself.
- Against Eunomius 2.11Basil of Caesarea · ca. 364 · Basil exposes the sophism in Eunomius's claim that the Son's essence 'was not before its own constitution,' showing that it implies the Son came from nothing and the Father became Father later.

- Against Eunomius 2.14Basil of Caesarea · ca. 364 · Basil answers Eunomius's dilemma ('God begot the Son either when he was or when he was not') from John 1:1: the Word 'was' in the beginning, beyond which nothing can be conceived, and John's prologue proclaims his eternal begetting.
- Against Eunomius 2.17Basil of Caesarea · ca. 364 · Basil answers Eunomius's claim that a Son who 'was' before his begetting would be unbegotten: the Son is eternally begotten, and 'eternal' and 'unbegotten' are different notions.
- Against Eunomius 2.18Basil of Caesarea · ca. 364 · Basil answers Eunomius's claim that the Son was begotten 'not being' by showing that the One who named himself 'He who is' at the burning bush was the Son, called in Scripture both angel and God.
- Against Eunomius 2.19Basil of Caesarea · ca. 364 · Basil denounces calling the Son 'not being,' a phrase Scripture uses of idols, and shows that the 'superiority' Eunomius grants the Son over his works does not imply a difference of essence from creatures.
- Against Eunomius 2.20Basil of Caesarea · ca. 364 · Basil rejects Eunomius's redefinition of 'Only-Begotten' as 'begotten and created by the only one,' briefly treats Prov 8:22 ('The Lord created me,' rendered by other translators 'acquired me'), and shows the absurd consequences of calling the Son a mere minister.
- Against Eunomius 2.22Basil of Caesarea · ca. 364 · Basil answers Eunomius's warning against a 'human' begetting: faith in Father and Son, into whom Christians are baptized, is the heart of the Gospel, and the names indicate a relation, not bodily passion.
- Against Eunomius 2.23Basil of Caesarea · ca. 364 · Basil argues that the names Father and Son, applied to God, point to the impassible cause, and that Christ himself transfers the name 'Father' from human beings to God.
- Against Eunomius 2.24Basil of Caesarea · ca. 364 · Basil argues that even if 'Father' were taken figuratively, Scripture's language of begetting points to kinship of nature, not passion; the manner of the begetting is ineffable but must be believed; and Eunomius contradicts himself about names and essences.
- Against Eunomius 2.25Basil of Caesarea · ca. 364 · Basil quotes Eunomius's dilemma about the Father and Son as 'light' and shows that the opposition he posits between unbegotten and begotten admits no common ground.
- Against Eunomius 2.26Basil of Caesarea · ca. 364 · Basil shows that Eunomius's reasoning would make the Son's 'light' the opposite of light, that is, darkness, and exposes the logical fallacy that consequents of contraries must themselves be contraries.
- Against Eunomius 2.27Basil of Caesarea · ca. 364 · Basil argues that Eunomius's formula would deny that the Son is light, life, and power, contrary to Scripture, and explains that darkness, death, and weakness belong to the powers that fell away by choice, not to any essence.
- Against Eunomius 2.28Basil of Caesarea · ca. 364 · Basil argues that 'unbegotten' and 'begotten' are distinguishing properties of Father and Son within one essence, not opposed essences, so that the one Godhead is known as Father and Son without contrariety.
- Against Eunomius 2.30Basil of Caesarea · ca. 364 · Basil rebuts Eunomius's claim that a 'law of nature' separates the Son's essence from the Father's, arguing that natural law, if anything, makes the offspring akin to the begetter.
- Against Eunomius 2.31Basil of Caesarea · ca. 364 · Basil shows that Eunomius contradicts himself by calling the Father's essence 'free of all laws' and yet bound by a 'law of nature,' and turns his chain of dignity, activity, and image into a proof that the Son is the image of the Father's essence.
- Against Eunomius 2.32Basil of Caesarea · ca. 364 · Basil argues that works reveal a maker's power, not his essence, and that if divine power and essence coincide, Eunomius's argument from works proves the likeness, not the unlikeness, of Father, Son, and Spirit.
- Against Eunomius 2.33Basil of Caesarea · ca. 364 · Basil denounces Eunomius as the first to call the Holy Spirit a 'work,' a blasphemy he uses to argue the Son's inferiority.
- Homilies 16.1Basil of Caesarea · ca. 363-378 · Expounding John 1:1, Basil shows that the Word's “beginning” has no beginning before it and that the fourfold “was” refutes the Arian “there was when he was not,” while “Word” and “with God” exclude both passion in the begetting and Sabellian confusion.
- Homilies 24.0Basil of Caesarea · ca. 363-378 · Title of Basil's homily against the Sabellians, Arians and Anomoeans.
- Homilies 24.1Basil of Caesarea · ca. 363-378 · The Sabellians renew Judaism by making Father and Son one person, the Anomoeans renew paganism by worshiping a created Son; Christ's own words show two persons and one nature.
- Against Auxentius 0Hilary of Poitiers · 364–365 · Hilary greets the bishops and peoples who hold the faith of the fathers against Arianism.
- Against Auxentius 6Hilary of Poitiers · 364–365 · The Arians give Christ titles that also fit angels and men while denying that he is true God; the people, hearing the words, believe rightly.
- Against Auxentius 8Hilary of Poitiers · 364–365 · Hilary analyzes how Auxentius's written creed attaches "true" to "Son" rather than to "God" and keeps the one divinity in the Father alone.
- Against Auxentius 11Hilary of Poitiers · 364–365 · Auxentius grants Christ only titles that Scripture also gives to men, Israel, and even the devil, while denying his true deity.
- Against Parmenian the Donatist 4.5Optatus of Milevis · ca. 366–385 · The Donatist bishops, who sit and teach, slander the Catholics in sermons and forbid their people even to greet them, misapplying texts meant for heretics such as Marcion, Praxeas, Valentinus, Arius and Photinus.
- Commentary on Philippians 2:10–12Ambrosiaster · ca. 366–384 · The name above every name given to Christ is the divine name he had by nature from his birth from the Father, made manifest after the cross; it was not given to a mere man or by adoption, against the Arians.

- Letter to the Africans 4Athanasius of Alexandria · ca. 369 · The bishops contrast Nicaea with the Arian councils that forbade speaking of God's essence or hypostasis, and show from Exodus, Jeremiah and Hebrews that hypostasis and essence mean God's very being.
- Letter to the Africans 5Athanasius of Alexandria · ca. 369 · The bishops explain how the council of Nicaea came to write “from the essence” and “of the same essence” because the Arians could twist every scriptural phrase, and cite earlier bishops and Eusebius of Caesarea for the term.
- Letter to the Africans 7Athanasius of Alexandria · ca. 369 · The bishops argue that the Son's oneness with the Father cannot be a likeness of virtue and will, as the Arians say, for that belongs to changeable creatures, but must be a likeness of essence.
- Letter to the Africans 9Athanasius of Alexandria · ca. 369 · The bishops explain that “of the same essence” means what the Nicene anathemas mean, that the Son is no creature, and urge the Africans to reject every council but Nicaea.
- Question 97, section 1Ambrosiaster · ca. 370–384 · Against the Arians, Christ is called the true Son of God, which means he was born from God’s substance; God’s power does not make false things true.
- Question 97, section 2Ambrosiaster · ca. 370–384 · Christ is God’s own Son, born of his substance, and therefore equal to him, as Paul and John testify.
- Question 97, section 4Ambrosiaster · ca. 370–384 · Everything Scripture ascribes to the Father it also ascribes to the Son, so the Arians misread the passages that show Christ’s true sonship.
- Question 97, section 8Ambrosiaster · ca. 370–384 · Father and Son are two by birth but one God by nature; since all things were made through Christ, he is not made but born, and the Arian “there was when he was not” is condemned.
- Question 97, section 9Ambrosiaster · ca. 370–384 · The Arian claim that God “made” Christ to be a true Son would replace birth with will and begetting with making.
- Question 97, section 10Ambrosiaster · ca. 370–384 · If God made Christ his true Son, Christ must be what God is and of one substance with him, which the Arians do not mean.
- Question 97, section 11Ambrosiaster · ca. 370–384 · To call Christ the true Son while denying his equality with the Father is a deceit, for true sonship implies equality.
- Question 97, section 12Ambrosiaster · ca. 370–384 · The Arian objection that a simple nature cannot beget is answered by God’s power, which also gave the virgin birth, Jonah’s survival, and the resurrection.

- On the Christian Faith 1.6Ambrose · ca. 378–380 · Ambrose proposes to answer the Arians from Scripture, names their divided leaders, and likens heresy to the Hydra and to Scylla, which the faithful must sail past.
- On the Christian Faith 1.7Ambrose · ca. 378–380 · From Paul’s calling Christ the image of the invisible God, from Wisdom 7:26, from John 14:9, and from Gen 1:26, Ambrose argues that the Son is not unlike the Father.
- On the Christian Faith 1.8Ambrose · ca. 378–380 · Ambrose argues that the Son is everlasting from Isa 43:10 and from the fourfold “was” of John 1:1–2, which he finds to refute Arius, Sabellius, Photinus, Eunomius, and the Manichaeans.
- On the Christian Faith 1.9Ambrose · ca. 378–380 · Ambrose argues that if the Father became Father at some point, he would have changed, so the Son’s eternal generation follows from God’s unchangeability.
- On the Christian Faith 1.11Ambrose · ca. 378–380 · Ambrose argues from Ps 81:9 that the Son is neither a “new” nor a “strange” God, and shows that arguments from the custom of human birth lead to absurdities.
- On the Christian Faith 1.12Ambrose · ca. 378–380 · Ambrose answers the objection that the Son lacks what sons have by arguing that nothing creaturely applies to God, that both Christ’s eternal generation and his birth from the Virgin are unique, and that they are to be believed, not examined.

- On the Christian Faith 1.16Ambrose · ca. 378–380 · Ambrose argues that “begotten” and “created” differ, that Paul forbids serving the creature yet calls himself Christ’s servant, and that a creature cannot exist in the simple nature of God.
- On the Christian Faith 1.17Ambrose · ca. 378–380 · Ambrose argues that the Son is true God and the Father’s own Son, from Rom 8:32, from his coming forth from God, from his sharing the Father’s work, from the confessions of the apostles and the centurion, and from Isa 65 and 1 John 5:20.
- On the Christian Faith 1.18Ambrose · ca. 378–380 · Ambrose quotes the Nicene Creed and its anathemas against the Arians, sees the cross and the name of Jesus in the number of the 318 bishops, and appeals to the Council of Ariminum.
- On the Christian Faith 1.19Ambrose · ca. 378–380 · Ambrose answers the anathematized Arian claims one by one: that there was when the Son was not, that he was not before he was born, that he is from nothing or from another substance, that he is a creature, and that he is changeable; he compares Arius’s death with that of Judas.
- On the Christian Faith 2.1Ambrose · ca. 378–380 · Ambrose answers the Arian use of Mark 10:18 (“No one is good but one, God”): Christ spoke as man to one who did not believe him God, and goodness belongs to the one divine nature, which includes the Son.
- On the Christian Faith 2.10Ambrose · ca. 378–380 · Ambrose explains that the Son’s obedience unto death (Phil 2:8) belongs to his incarnation, shows the one power and work of the Trinity from the passion and from Paul’s prayers, and compares the Son’s subjection to his subjection to Joseph and Mary.
- On the Christian Faith 2.13Ambrose · ca. 378–380 · Ambrose imagines the Arian, the Photinian, the Sabellian, and the Manichaean pleading before Christ the judge, each condemned by his own denial, and ends with his own plea for mercy.
- On the Christian Faith 2.15Ambrose · ca. 378–380 · Ambrose closes the second book: Peter’s confession is enough for faith, the Arians shut their ears like those who heard the Father’s voice as thunder, and Paul and John warn against such sowers of questions and antichrists.
- On the Christian Faith 3.6Ambrose · ca. 378–380 · Ambrose answers the Arian use of John 1:3–4 (“what was made in him”) by discussing its punctuation and showing that things are said to be “made in God” without belonging to his substance.
- On the Christian Faith 3.8Ambrose · ca. 378–380 · Ambrose reads Isa 9:6 (“a child is born, a Son is given to us”) as distinguishing Christ’s human birth from his eternal sonship, and as excluding Jews, Manichaeans, Marcionites, Photinians, Sabellians, and Arians.
- On the Christian Faith 3.15Ambrose · ca. 378–380 · Ambrose defends the Nicene word homoousios (“of one substance”) against the Arians, recalling that Eusebius of Nicomedia rejected it, explaining that it signifies distinction of persons and unity of nature, and urging fidelity to the faith sealed by confessors and martyrs.
- On the Christian Faith 3.16Ambrose · ca. 378–380 · Ambrose warns against Arian formulas that sound orthodox, such as “not a creature like the other creatures,” and insists that Christ be confessed as true God with the Father’s full divinity, seated at his right hand.

- On the Christian Faith 4.3Ambrose · ca. 378–380 · Ambrose answers the Arian use of 1 Cor 11:3 (“the head of Christ is God”) as said of Christ’s humanity, and distinguishes the unity of Father and Son by nature from the unity of believers by grace (John 17).
- On the Christian Faith 4.8Ambrose · ca. 378–380 · Ambrose answers the Arian claim that the Son is unequal because he did not beget a son: begetting belongs to the Father’s property, not to power or nature, and the Son, of one substance with the Father, has all that the Father has.
- On the Christian Faith 4.9Ambrose · ca. 378–380 · Ambrose answers the Arian dilemmas about the Son’s generation (whether he existed before he was begotten, whether generation began, whether it was willed) by showing that the generation is eternal, like radiance from light, and that even human beings such as Jacob, Jeremiah, and John existed in some sense before birth.
- On the Christian Faith 5.1Ambrose · ca. 378–380 · Ambrose argues that John 17:3 (“you, the only true God, and Jesus Christ”) joins the Son to the Father, and that Christ, being neither a false god nor a god in name only, is true God, the same yesterday, today, and for ever.
- On the Christian Faith 5.3Ambrose · ca. 378–380 · Ambrose answers the Arian charge that one substance means two gods: Scripture uses plurality for things of different substance, while Father and Son, being of one substance, are one God, to be served and worshiped together.
- On the Christian Faith 5.8Ambrose · ca. 378–380 · Ambrose explains that Christ calls the Father “Lord” in respect of his servant form, uses Christ’s question about David’s son and Lord to refute several heresies, and refers texts about Christ as servant and being glorified to his incarnation.
- On the Christian Faith 5.9Ambrose · ca. 378–380 · Ambrose answers the Arian argument from the order of names in the baptismal formula by showing that Scripture often names the Son before the Father.
- On the Christian Faith 5.11Ambrose · ca. 378–380 · Ambrose explains that the Son’s speaking what he hears from the Father expresses their unity of will, and gives a series of arguments that the Son is not a creature.
- On the Christian Faith 5.16Ambrose · ca. 378–380 · Ambrose answers the Arian use of Mark 13:32 (“nor the Son”) by noting that older Greek manuscripts of Matthew lack the words, by explaining them of Christ’s human nature, and by arguing that the Creator of the ages, who foretold the signs, the place, and the order of the end, cannot be ignorant of the day.
- On the Christian Faith 5.18Ambrose · ca. 378–380 · Ambrose gives two explanations of “nor the Son” (love that withholds useless knowledge, and the human condition Christ assumed), then argues that the Son, who has all that the Father has, is less only according to the flesh, and that no creature may sit in judgment on the Father and the Son.
- On the Christian Faith 5.19Ambrose · ca. 378–380 · Ambrose turns in prayer to the Father: no one may measure God or judge between the Father and the Son, and Arius, claiming to know God wholly, outdoes Paul in presumption and imitates the devil’s boast.

- On the Making of Man 6Gregory of Nyssa · 379 · Just as one human mind works through many senses, God is not divided by his many powers; and since the three persons make one image, they cannot be unlike in nature, as the Anomoeans claim.

- On the Trinity 1Faustinus · ca. 380–384 · Faustinus sets out the Arian position and refutes it from John 1, Philippians 2, Colossians 1, Genesis 1, and 'I and the Father are one,' arguing that the Son is eternal, equal, and of one substance and will with the Father.
- On the Trinity 2Faustinus · ca. 380–384 · Against the claim that God made the Son from nothing, Faustinus cites the Father's voice at the baptism and transfiguration, Peter's confession, John's 'only-begotten' texts, God's gift of his Son compared with Abraham's offering of Isaac, and Psalm 110:3, 'from the womb I begot you.'
- On the Trinity 3Faustinus · ca. 380–384 · Faustinus proves the Son almighty and unchangeable from Zechariah, Revelation, Wisdom, the Psalms, and Isaiah, and explains Christ's weaknesses as belonging to the human nature he assumed.
- On the Trinity 5Faustinus · ca. 380–384 · Acts 2:36, 'God made him Lord and Christ,' refers to Jesus according to the flesh, who became Lord of those who serve him and Christ, King and Priest, by the anointing of the Spirit, not to the making of the Word's substance.
- On the Trinity 6Faustinus · ca. 380–384 · Proverbs 8:22, 'the Lord created me,' does not make Wisdom (Christ) a creature: Wisdom was begotten before it was 'created' for God's works, and 'created' can mean being made something for others, as God is 'made' our refuge.
- Theological Oration 3 (Or. 29), On the Son 5Gregory of Nazianzus · 380 · God is Father eternally and in the proper sense; biblical tenses show that “he begot” need not imply a temporal beginning.

- Theological Oration 3 (Or. 29), On the Son 10Gregory of Nazianzus · 380 · If “unbegotten” were God’s substance, the begotten Son could not be God; but unbegotten and begotten are properties within one and the same nature.
- Theological Oration 3 (Or. 29), On the Son 11Gregory of Nazianzus · 380 · Being unbegotten is a property of the Father, not the divine substance; the Son, begotten of the Father, is equally God.
- Theological Oration 3 (Or. 29), On the Son 12Gregory of Nazianzus · 380 · Being unbegotten and being God are not the same, or the Eunomian logic would make the Son’s substance older than the Father’s.
- Theological Oration 3 (Or. 29), On the Son 14Gregory of Nazianzus · 380 · The Eunomian appeal to equivocal names, like the land dog and sea dog, fails because it is meant to make the Son unequal to the Father.
- Theological Oration 3 (Or. 29), On the Son 15Gregory of Nazianzus · 380 · The Father is greater as the Son’s cause, but the Eunomians fallaciously conclude that he is greater in nature.

- Theological Oration 5 (Or. 31), On the Holy Spirit 19Gregory of Nazianzus · 380 · Using 1 John 5:8 and common equivocal names, Gregory shows that the Eunomian rules about counting and names prove nothing about substance.
- To Simplicius on Faith, part 1Gregory of Nyssa · ca. 380–394 · Against those who say the Son once was not and is created, Gregory argues from the commands against a "new" or "foreign" god that such a Son could not be worshipped, and explains "The Lord created me" (Prov 8:22) of the humanity the Word became for our sake.
- To Simplicius on Faith, part 2Gregory of Nyssa · ca. 380–394 · Christ is both divine by nature and human by the economy; the Son is eternal as the radiance of the Father's glory is never without the lamp, and as the express image of the Father's hypostasis he cannot be less than the Father, since the Word was in the beginning and wholly with God.
- Chapter 3Nicetas, bishop of Remesiana · ca. 380–414 · Nicetas explains that Arius, prying into how God begets, denied both Father and Son, and that Nicaea confessed the Son born from the Father’s substance, “of one substance with the Father.”

- Petition to the Emperors (Libellus precum) 7Faustinus · ca. 383–384 · The petition recalls the condemnation of Arius at Nicaea and the story of his sudden and shameful death in a privy at Constantinople, after bishop Alexander prayed that he not be received into the church.
- Petition to the Emperors (Libellus precum) 8Faustinus · ca. 383–384 · Arius's death shows God's judgment on his doctrine and on all who revive it, and confirms as true Catholics those who suffer for the Nicene faith; but Arius left heirs, like worms bred from his corpse.
- Petition to the Emperors (Libellus precum) 9Faustinus · ca. 383–384 · The heirs of Arius, with Constantius's support, persecuted Catholic bishops and summoned the councils of Seleucia and Ariminum (359); at Ariminum the bishops at first upheld Nicaea and condemned the formula of Ursacius and Valens, but their envoys to the emperor gave way under pressure.
- Petition to the Emperors (Libellus precum) 10Faustinus · ca. 383–384 · The bishops at Ariminum and Seleucia, fearing exile more than eternal punishment, signed the Arian formula; the petitioners ask why they should be punished for refusing communion with such bishops.

- Second Apology of David 26Ambrose · ca. 384-397 · Christ’s question about Psalm 110 refutes not only the Jews but Photinians, Sabellians, and Arians: the Son, distinct from the Father, shares his throne and power.

- Sermon 117.10Augustine of Hippo · ca. 391-430 · The Arians’ examples show only temporal sons later than temporal fathers; a likeness can be found instead in things coeval, begotten and begetter beginning together, which point to the Son coeternal with the eternal Father.
- Sermon 117.11Augustine of Hippo · ca. 391-430 · Scripture calls Wisdom the brightness of eternal light; just as the brightness of a lamp comes from the fire yet exists together with it, the begotten need not be later than the begetter.
- Sermon 118.1Augustine of Hippo · ca. 391-430 · The Word who was in the beginning was not made, since all things were made through him, but begotten of the Father; Father and Son are one God, and the Arian claim that there was a time when the Word was not is false.
- Sermon 118.2Augustine of Hippo · ca. 391-430 · The Son is the Father’s brightness, as Scripture calls Wisdom the brightness of eternal light; as fire is never without its splendor, the Father is never without the Son, who is always born and coeternal.

- Sermon 139.3Augustine of Hippo · ca. 391-430 · Against the Arian objection that a father is greater than his son, Augustine replies that this difference is one of age, not nature, and has no place in eternity; a Son of another substance than the Father would be a monster.
- Sermon 139.4Augustine of Hippo · ca. 391-430 · God, who gave creatures the power to beget their own kind, did not beget a Son of another substance; to call the Son degenerate by nature is a greater insult than calling a coward his brave father’s degenerate son.
- Sermon 139.5Augustine of Hippo · ca. 391-430 · Augustine urges prayer for the Arians, many of them Arian by upbringing; by claiming to honor the Father at the Son’s expense they insult both, as a son and father are both insulted when the son is called degenerate.
