Which of these heresies is the worst?

[President Punxsutawney Phil]

     Impressed by the unanimity of opinion for Docetism. I would have to agree with the other posters in this thread, since Docetism denies the reality of the Crucifixion and thus leaves us without an atonement for our sins.

The Cathars, much later on, said that Jesus was really an Angel in human form as the human flesh was too corrupt. The belief was still practiced many times after it was deemed heretical. I’m an atheist and even I find it bizarre.

Yeah, I hear you, but outside of that Cathars sound pretty based

Cathars had a rather unhealthy attitude towards sexual activities.
