Acts 18:4-6

4. He disputed in the synagogue It is a wonder how that crept in which is in the Latin books, that Paul put in the name of Christ: unless it were because some reader would supply the want of the general sentence. For Luke setteth down two things in this place: to wit, that Paul disputed among the Jews; secondly, that he began more plainly to profess Christ after that Silas and Timotheus were come. And though it be likely that he began to speak of Christ even at the first entrance, because he could not omit the principal point of the heavenly doctrine, yet that doth not hinder but that he might use some other manner of disputation. Therefore I take [πειθειν] that is, to persuade, for to induce by little and little. For, in my judgment, Luke doth signify, that forasmuch as the Jews did handle the law coldly and foolishly, Paul spake of the corrupt and wicked nature of man, of the necessity of grace of the Redeemer which was promised, of the means to obtain salvation, that he might awake them; for this is a fit and brief preparation unto Christ. Again, when he saith that he was forced in spirit to teach that Jesus was Christ, his meaning is, that he was enforced with greater vehemency to intreat and speak of Christ freely and openly. So that we see that Paul did not utter all things at one time, but he tempered his doctrine as occasion did serve.

And because like moderation is profitable at this day, it is convenient for faithful teachers wisely to consider where to begin, lest a preposterous and confused order do hinder the proceeding of doctrine. Furthermore, though there were ferventness enough in Paul, yet it is no inconvenient thing that he was made more courageous by some new help, not that he was encouraged by shame, or the hope which he reposed in his fellows, but because he considered that this help was sent him, as it were, from heaven. But this forcing in the spirit is not taken for a violent or external impulsion, (as they say, ) as those which were called Phoebades and frantic men were wont to be carried away with devilish madness; but there was more ferventness added unto the wonted inspiration of the Spirit which was in Paul, so that he was moved with new power of God, and yet did he of his own accord follow the Spirit as his guide. Whereas Paul did testify that Jesus is Christ, I expound it thus: when he had thoroughly taught the Jews concerning the office of the Redeemer, he declared by testimonies of Scripture that this is he which was to be hoped for, because all those things agree to him which the law and the prophets attribute to Christ. Therefore, he did not simply affirm, but using a solemn testification, he proved Jesus, the Son of Mary, to be that Christ who should be the Mediator between God and men, that he might restore the world from destruction to life.
