Saint Augustine of Hippo first works his way through the Creed, and then the Lord's Prayer as recorded by Matthew, ending with the sacraments. This is a colossal work in one small volume.
Written as a favor for a friend, this "little work" is a wonderful explanation of the Christian faith: a true catechism from which, throughout the history of the church, other catechisms have drawn and learned. The Bishop of Hippo organized the content according to the three graces necessary for the Christian worship of God: Faith, Hope and Love.
