St. Augustinspeaks of this book in his Retractations, l. ii. c. 63, as follows: "I also wrote a book on Faith, Hope, and Charity, at the request of the person to whom I addressed it, that he might have a work of mine which should never be out of his hands, such as the Greeks call an Enchiridion (Hand-Book).

Under the second head he gives a brief exposition of the Lord's Prayer. The third part is a discourse on Christian love.
