Even Bart Ehrman — a non-Christian scholar whose goal is to undermine Christianity — dates John to 90–95 AD, not 170 AD

Bart Ehrman takes the late-date view but still places John at 90–95 AD. This demonstrates that even scholars hostile to Christianity do not accept the 170 AD date Jim presents. The point: skeptics should not trust Jim as a source if even their own preferred scholars contradict him.
