This revised edition of the standard history of the first great period in Christian thought has been thoroughly updated in the light of the latest historical findings. Dr. Kelly organizes an ocean of material by outlining the development of each doctrine in its historical context. He lucidly summarizes the genesis of Chrisitian thought from the close of the apostolic age to the Council of Chalcedon in the fifth century–a time teeming with fresh and competing ideas. The doctrines of the Trinity, the authority of the Bible and tradition, the nature of Christ, salvation, original sin and grace, and the sacraments are all extensively treated in these pages.

This revised edition of Early Christian Doctrines includes:

• Sweepingly updated early chapters
• Revised and updated bibliographies
• A completely new chapter on Mary and the saints
