I’ve noticed that Michael Bird has recently posted an article on heresy and orthodoxy in early Christianity. From what I can tell (I can’t see the entire article because it’s behind the paywall), he is pushing back against the popular narrative, originally suggested by Walter Bauer in his 1934 book Orthodoxy and Heresy in Earliest…Where Are All the Heretical Bishops in the Second Century? — Canon Fodder
Here is good evidence for general Christian orthodoxy just after the Apostolic Era. I am about half way through Kruger’s book Christianity at the Crossroads which is giving me a better understanding of Church History. In my training, now many years removed, I specialized in languages and even more so theology. Church history, while I had the seminary requirements, I never regarded as crucial since Church History is not the same as the biblical History of Israel. Anyway, I appreciate Kruger’s book countering Bauer’s errors while understanding more about Christianity’s heritage.
