1Nicetas says that those preparing for baptism need simple instructions drawn from Scripture on what they renounce, desire, receive and must keep.
2Nicetas describes the catechumen as a guest who hears the mysteries from outside until baptism makes him one of the faithful.
3Nicetas teaches that before confessing the faith the candidate must sincerely renounce the devil and his works, including pagan cults, shows and vices, and condemns vain male and female adornment.
4After renouncing the devil, the candidate recites the creed, which he must learn by heart and say daily, together with the Lord’s Prayer and the sign of the cross.
5Nicetas defines the creed as a reminder of the faith and a common holy confession.
6Nicetas explains that the exorcisms before baptism purge the candidates like fire, being made of the Lord’s fiery words.
