That's not right. You should read the letter yourself. My favorite parts include the phoenix being real and salvation through faith.
The letter offered unsolicited advice. Since no one said he shouldn't have sent it, it is therefore assumed that he had the right to send it. Hence, he was over them and therefore supreme.
‘unsolicited advice’ is ignored....
however, direction from one in authority is not ignored...
so how did that exactly workout - ignored or not ignored.
