The First Apology
Chapter 6: Refuting the Accusation of Atheism
This is why we are called atheists. And we admit that we are atheists regarding gods of this type, but not in relation to the most true God, the Father of righteousness, temperance, and the other virtues, who is free from all impurity. But we worship and adore both Him, and the Son (who came from Him and taught us these things, along with the host of other good angels who follow and are made like Him), and the prophetic Spirit, knowing them through reason and truth, and willingly sharing with everyone who wishes to learn, as we have been taught.
