To the Nations 1.13

Others, indeed, more humanely think that the sun is the Christians' god, because it has become known that we pray toward the east, or make holiday on the day of the sun. What? Do you do less? Do not most of you, in an affectation of worshipping the heavenly bodies, at times move your lips toward the sunrise? It is you, surely, who have even taken the sun into the calendar of the seven days, and among the days have preferred it to the day before it, a day on which you give up your bath or put it off until evening, or devote yourselves to rest and feasting. This you do in turning aside from your own religions to foreign ones. For the Jewish feasts, the sabbaths and the “pure supper,” and the Jewish rites of lamps, and fasts with unleavened bread, and prayers by the shore, are all surely foreign to your gods. So, to return from this digression: you who reproach us with the sun and its day, acknowledge the kinship; we are not far from your Saturn and your sabbaths.
