So was Paul going against the word of Christ when he wrote this?
"I do not write this to make you ashamed, but to admonish you as my beloved children. For though you have countless guides in Christ, you do not have many fathers. For I became your father in Christ Jesus through the gospel" (1 Cor. 4:1415).
