The Bible does not even mention a follower of Paul. I don't know where the anti-Christians came up with that.
I found out these words of Paul:
1 Cor. 1:
10 Now I urge you, brothers, through the name of our Lord Jesus Christ, that you should all speak in agreement and that there should be no divisions among you, but that you may be completely united in the same mind and in the same line of thought.
11 For some from the house of Chloʹe have informed me regarding you, my brothers, that there are dissensions among you.
12 What I mean is this, that each one of you says: “I belong to Paul,” “But I to A·polʹlos,” “But I to Ceʹphas,” “But I to Christ.”
13 Is the Christ divided? Paul was not executed on the stake for you, was he? Or were you baptized in the name of Paul?
14 I thank God that I baptized none of you except Crisʹpus and Gaʹius,
15 so that no one may say that you were baptized in my name.
16 Yes, I also baptized the household of Stephʹa·nas. As for the rest, I do not know whether I baptized anyone else.
17 For Christ sent me, not to baptize, but to declare the good news; and not with wisdom of speech, so that the torture stake of the Christ should not be made useless.
Does that mean that Paul made his own religion, or just the opposite?
