2 Corinthians 11:4

The Jesus they were preaching was different enough from Him whom Paul preached that Paul could say their Jesus was a different person. The "if" in this verse does not represent a hypothetical possibility but a past reality. In listening to the false teachers’ message the church was under the influence of some sort of spirit, but it was not the Holy Spirit. They were in danger of accepting a different gospel (cf. 2 Corinthians 10:5; Galatians 1:8-9). In all this they were bearing up "beautifully." Paul described ironically their accepting it all very graciously and submissively from the false apostles (cf. 2 Corinthians 10:7). Since they showed such remarkable toleration of false teachers surely they owed their father in the faith the same toleration.

This is the second reason the Corinthians should bear with Paul (2 Corinthians 11:1): their willingness to accept visitors who presented an adulterated message.
