25. He was instructed. That which Luke addeth shortly after seemeth not to agree with this commendation, to wit, that he knew only the baptism of John. But this latter member is added by way of correction. Nevertheless, these two agree very well together; that he understood the doctrine of the gospel, because he both knew that the Redeemer was given to the world, and also was well and sincerely instructed concerning the grace of reconciliation; and yet had he been trained up only in the principles of the gospel, so much as could be had out of John’s institution. − (346) For we know that John was in the midst between Christ and the prophets; and of his office doth both his father Zacharias intreat in his tongue, ( Luke 1:76; Luke 1:16 and 17;) and also the angel out of the prophecy of Malachi, ( Malachi 3:1.) Surely, seeing that he carried the light before Christ, and did highly extol his power, his disciples are for good causes said to have had knowledge of Christ. Moreover, the speech is worth the noting, that he knew the baptism of John. For thence we gather the true use of the sacraments; to wit, that they enter − (347) us in some certain kind of doctrine, or that they establish that faith which we have embraced. Surely, it is wickedness and impious profanation to pull them away − (348) from doctrine. Wherefore, that the sacraments may be rightly administered, the voice of the heavenly doctrine must sound there. For what is the baptism of John? Luke comprehendeth all his ministry under this word, not only because doctrine is annexed unto baptism, but also because it is the foundation and head thereof, without which it should be a vain and dead ceremony. −

Being fervent in spirit he spake. Apollos hath another commendation given him in these words, that he was inflamed with an holy zeal to teach. Doctrine without zeal is either like a sword in the hand of a madman, or else it lieth still as cold and without use, or else it serveth for vain and wicked boasting. For we see that some learned men become slothful; other some (which is worse) become ambitious; other some (which is of all the worst) trouble the Church with contention and brawling. Therefore, that doctrine shall be unsavory which is not joined with zeal. But let us remember that Luke putteth the knowledge of the Scripture in the first place, which must be the moderation of zeal, − (349) for we know that many are fervent without consideration, as the Jews did rage against the gospel, by reason of a perverse affection which they did bear toward the law; and even at this day we see what the Papists be, who carried headlong with furious violence, being pricked forward with an opinion unadvisedly conceived. Therefore, let knowledge be present that it may govern zeal. And now it is said that zeal was the cause of diligence, because Apollos gave himself to teach diligently. But and if that man, being not yet thoroughly and perfectly taught in the gospel, did preach Christ so diligently and freely, what excuse do those men hope to have, who know that more perfectly and fully, which he knew not as yet, if they do not endeavor so much as in them lieth to further and advance the kingdom of Christ? Luke doth attribute zeal to the Spirit, therefore, because it is a rare and peculiar gift; neither do I so expound it that Apollos was moved and pricked forward with the instinct of his mind, but by motion of the Holy Spirit. −
