 I started criticizing the trinity and with it the crucifixion because if we believe that God had to become a human in order to forgive our sins, this would imply that he wasn't perfect to begin with. Why would God need a human experience in order to do anything? Of course, he does not. He is the origin of everything. He is perfect to begin with. He has no beginning, no end. There is no time frame within him, within his eternity, so why would he need to incarnate to do anything?
