The Apology
Aristides composed his Apology to demonstrate that Christians alone hold the true conception of God. The work surveys humanity and the various understandings of the divine, critiquing the religious errors attributed to the Chaldeans, Greeks, Egyptians, and Jews, and contrasting them with Christian belief.
The surviving text divides humanity into races or peoples and argues for the moral excellence of Christian living against the corrupt practices of paganism. Its tone is described as elevated and calm, relying on plain appeals rather than elaborate argument, and it emphasizes the virtue and humility of the Christians of Aristides's day.
