There is significant evidence that many early Christian groups had rather questionable sexual practices.

Perhaps you mean the gnostic/christian cults?

Paul indicates that many were Saved from destructive sexuality, and he condemned some who wandered back into it; but there's no indication that the orthodox believers ever considered unnatural sexuality to be blessed.

Gnostics did; backsliders did....John suggests that Pergamum and Thyatira were both "types" of churches AND problem-plagued churches.

Is that what you mean?
