It is hard to imagine, but even in the first century, there were members of the church who gained enough influence and power, that they opposed living apostles,
I wrote to the church, but Diotrephes, who loves to have the preeminence among them, does not receive us. Therefore, if I come, I will call to mind his deeds which he does, prating against us with malicious words. And not content with that, he himself does not receive the brethren, and forbids those who wish to, putting them out of the church (3 John 9–10).
If you meet someone like that, beware, he will fight you ruthlessly, if you do not go along with his hunger for power. However, be strong and oppose him.
