Mom, I must be pretty naive. I did not think there were people out there claiming sinless perfection. Maybe I was wrong.
You are. Although those of us who believe the doctrine don't care for the term 'sinless perfection' much, since it holds all sorts of negative connotations for many people. We tend to prefer the terms 'entire sanctification,' 'Christian perfection,' or 'full redemption.' Some use the term 'baptism in the Spirit,' although they understand what the baptism in the Spirit is wrongly, saying that it does not occur at regeneration, but comes later.
