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?

Gnostics especially, but also various other local churches.

There was no official orthodoxy until the third century, and even then there were various schisms, some of which survive to the modern world.
