This brief manual or handbook of Christian doctrine, based largely on a running exposition of the Apostles' Creed and the Lord's Prayer, contains St. Augustine in essence: a summary of all the elements in his teaching that made him a Doctor of the Church and also those that cause the Christian East to want to strongly footnote that assignation. Written in the last years of his career and in his full theological maturity, this work is a microcosmic preview of medieval Catholic theology, especially in its descriptions of predestination and grace, original sin and baptism, the role of the Blessed Virgin, and the interim state of the dead and the future life. This edition concludes with a detailed analysis by Adolf von Harnack.

..".the ideas of this man furnished the themes for the piety and theology of more than a thousand years. No one possessed the "whole" Augustine, but all lived upon the fragments of his spirit from which each appropriated and understood what was "adapted" to his own wants."
