Paula

I can quote Paul too:

Gal. 5:7 You were running a good race. Who cut in on you and kept you from obeying the truth? 8 That kind of persuasion does not come from the one who calls you. 9 “A little yeast works through the whole batch of dough.” 10 I am confident in the Lord that you will take no other view. The one who is throwing you into confusion will pay the penalty, whoever he may be. 11 Brothers, if I am still preaching circumcision, why am I still being persecuted? In that case the offense of the cross has been abolished. 12 As for those agitators, I wish they would go the whole way and emasculate themselves!

1 Cor. 4:18 Some of you have become arrogant, as if I were not coming to you. 19 But I will come to you very soon, if the Lord is willing, and then I will find out not only how these arrogant people are talking, but what power they have. 20 For the kingdom of God is not a matter of talk but of power. 21 What do you prefer? Shall I come to you with a whip, or in love and with a gentle spirit?

Paul’s “think differently” statement, in context, is about “straining for the goal”, not accepting false teachings. That would make him contradict himself. He could be very “in your face” with the arrogant and the false teachers.
