God is the most humble and yet He is perfect.
Being truly humble is a sign of perfection. But your argument is 100% valid with a creation. If a creation claims to be perfect, it is not evidence of humility.
Humility is at the core of Christianity. Pride the core of satanism.
So, if we espouse to be perfect we better come with a good defense. In Peace's defense, he does come with scripture. A lot of it. I don't agree with his interpretation of it all. But nobody can doubt that in his mind, he is convinced. He is not trying to deceive anyone. He truly believes it. His intentions are therefore good. I am judging you at Peace , as that is what we are called to do.
