A collection of Christian instruction and apologetics addressed to pagans and new converts, arguing against pagan rites and images, exposing sacrificial cruelty and moral corruption, and urging followers to worship the divine Word and God the Father. It combines scriptural exposition with philosophical and poetic witnesses to defend Christian doctrine, answers objections about ancestral customs, and outlines benefits of Christ. A practical manual then presents Christ as the moral Instructor and gives detailed guidance for daily conduct—food, dress, speech, associations, bathing, sleep, adornment, frugality, and true beauty—to shape a disciplined Christian character.
