Alan Kreider 
The Change of Conversion and the Origin of Christendom [PDF ebook] 

First-class insight into the life and mission of the Christian church in the first four centuries, based on solid scholarship and a clear sense of mission.
–Samuel Escobar, Palmer Theological Seminary
Written in a lively and clear manner, this small volume makes many connections between different aspects of early Christian history and practice. I have learned from reading it and recommend it to both scholars and beginners.
–Paul Bradshaw, University of Notre Dame
Kreider traces the changing nature of the process of conversion across some four centuries. I know of no better treatment of religious initiation undergone by the most seriously committed Christians of this period.
–Ramsay Mac Mullen, Yale University
I recommend this book highly to anyone interested not only in the history and theology of Christian initiation, but in the relationship of Christianity and culture throughout the ages.
– Maxwell E. Johnson, University of Notre Dame, in ‘Worship’
