Originally published in German in 1968 under the title
Einführung in das Christentum, Ratzinger restates the
Apostles' Creed and the meaning of this foundational text in language that has a greater contemporary resonance than the Creed itself. Like the Apostles' Creed, the book presents the doctrines pertaining to the Father, the Son, and the Spirit in sequence. The book lays the foundations for a new kind of theological
exegesis of the
Bible, based on the document
Dei verbum of the
Second Vatican Council (1962-1965), co-authored by Joseph Ratzinger, which combines two quite different ways of
hermeneutics, the interpretation of faith and historical-critical interpretation. This exegesis of the Bible is fully developed in his book
Jesus of Nazareth, published in two volumes as Pope in 2007 and 2011, some of whose ideas are rooted in
Introduction to Christianity. ==Editions==
