2 Corinthians 11:4-6

For [you seem willing to allow it] if one comes and preaches another Jesus whom we have not preached, or if you receive a different spirit from the one you received, or a different gospel from the one you accepted. You tolerate all this beautifully [welcoming the deception]. Yet I consider myself in no way inferior to the [so-called] super-apostles. But even if I am unskilled in speaking, yet I am not [untrained] in knowledge [I know what I am talking about]; but we have made this evident to you in every way, in all things.
