On Christian Teaching is one of Augustine`s most important works on the classical tradition. Written to enable Christian students to be their own interpreters of the Bible, it provides an outline of Christian theology, a detailed discussion of ethical problems, and a fascinating early contribution to sign theory. Augustine also makes a systematic attempt to determine what elements of classical education are permissible for a Christian, and in the last book suggests ways in which Ciceronian rhetorical principles may help in communicating the faith. This long-needed, completely new and up-to-date translation gives a close but stylish representation of Augustine`s thought and expression. References to the classical background are carefully explained and Roger Green`s introduction describes the aims and circumstances of the work, and outlines its influence on major figures in the Middle Ages and the Renaissance.
