Can anyone recommend a reliable book or source explaining the early church heresies (besides the Bible) 33-150 AD? I’m looking for something that will describe docetism, adoptionism, marcionism, gnosticism, etc and how the orthodox view was, in fact, the dominant one.
Since you already think you know the answer, why are you asking for a reference?
It sounds as if all you want is a book to wave in other people’s faces, not something that will actually help you learn.
What would it do to your faith if you learned that the orthodox view was not in fact the dominant one?
As a matter of fact, I think that it probably was–at least, I’m not convinced by the arguments to the contrary. But we believe in orthodox Christianity because it’s true, not because it is or was dominant. If it turned out that there were more Marcionites or Valentinians or Montanists than Catholic Christians in 150 A.D., that wouldn’t make those heresies right.
Chapter 2 of vol. 1 of Jaroslav Pelikan’s
The Christian Tradition does a good job of summarizing the various early heresies and the formation of orthodoxy. Pelikan was a Lutheran at the time and eventually became Orthodox, so this is a relatively conservative take.
J. N. D. Kelly’s
Early Christian Doctrines is a classic survey, and of course he talks about early heresy as well as the formulation of the orthodox response. A more recent survey of early Christian literature is
The Cambridge History of Early Christian Literature, which has chapters on the Gnostics and other heretical literature.
The book that may best correspond to what you’re looking for is
The Heresy of Orthodoxy by Andreas Kostenberger and Michael Kruger. I just found out about it–it looks interesting and I hope to get around to reading it sometime soon.
