2 Corinthians 11:4

For if he that cometh preacheth another Jesus, whom we did not preach, or if ye receive a different spirit, which ye did not receive, or a different gospel, which ye did not accept, ye do well to bear with him. [These first four verses are introductory. The apostle, seeing the effect which the self-glorification of these false teachers has had upon certain of the Corinthians, determines, for a time, to adopt their tactics, descend to the foolishness of boasting, and thus overcome them on their own ground. Paul, in his consecration to Christ and forgetfulness of self, could not thus descend to the level of boasting, even though he merely related facts, without a sense of shame and a petition for consideration. When he considers the folly of the situation, it seems to him that the Corinthians could not put up with it, but when he remembers their affection for him, he is sure they will. He tells them that nothing but the strongest motives could induce him to thus belittle himself, but he found such a motive in his extreme jealousy for them on Christ's behalf. As the paranymph, or "bridegroom's friend" (John 3:29), the one whose office it was to procure and arrange the marriage, he had espoused them to one husband, even Christ, and had so instructed and led them as to present them pure and spotless before the Lord at his coming. But now he feared that as the serpent led Eve into sin by his crafty wickedness, so these false teachers were corrupting the church at Corinth from that simplicity of doctrine and purity of life which they owed to Christ, their espoused husband. Now, if these false teachers (and Paul speaks of one of them as a sample of them all) had come professing to preach another Jesus and another religious spirit, and a different gospel from any that Paul preached, there might have been sonic excuse in giving them a patient hearing. But such had not been the case. Professedly they were preaching the same Jesus, etc., that he did, and so the Corinthians were without excuse in permitting them to assail Paul. They had sold their apostle and had received nothing in exchange for him. With the next verse his boasting begins, but in a very mild and apologetic form.]
