A discussion of 'primitive' Christianity - Christianity in its original form, this work was first given as Speaker's Lectures in Oxford. Covering the first five centuries of Christianity, it argues that neither a theology of the New Testament nor a history of the early Church can do justice to all the dimensions of the earliest Christianity. It explores in depth the formation of primitive Christianity and studies the effect of the two great crises of primitive Christianity: the split with Judaism and the threat from Gnosticism. It is aimed at academic theologians.

Contents: v.1. the lost lives of Jesus Christ and the apostles and the authentic gospel of St. John--v.2. the religion of Jesus Christ.
