"In the beginning was Diversity. And the Diversity was with God, and the Diversity was God. Without Diversity was nothing made that was made. And it came to pass that nasty old 'orthodox' people narrowed down diversity and finally squeezed it out, dismissing it as heresy. But in the fullness of time (which is of course our time), Diversity rose up and smote orthodoxy hip and thigh. Now, praise be, the only heresy is orthodoxy. As widely and as unthinkingly accepted as this reconstruction is, it is historical nonsense: the emperor has no clothes. I am grateful to Andreas Köstenberger and Michael Kruger for patiently, carefully, and politely exposing this shameful nakedness for what it is."

"The Heresy of Orthodoxy will help many to make sense of what is happening in early Christian studies today. It explains, critiques, and provides an alternative to, the so-called 'Bauer Thesis,' an approach which undergirds a large segment of scholarship on early Christianity. The 'doctrine' that Christianity before the fourth century was but a seething mass of diverse and competing factions, with no theological center which could claim historical continuity with Jesus and his apostles, has become the new 'orthodoxy' for many. The authors of this book do more than expose the faults of this doctrine, they point the way to a better foundation for early Christian studies, focusing on the cornerstone issues of the canon and the text of the New Testament. Chapter 8, which demonstrates how one scholar's highly-publicized twist on New Testament textual criticism only tightens the tourniquet on his own views, is alone worth the price of the book. Köstenberger and Kruger have done the Christian reading public a real service."
