8. He that planteth, and he that watereth are one He shows farther, from another consideration, that the Corinthians are greatly to blame in abusing, with a view to maintain their own sects and parties, the names of their teachers, who in the meantime are, with united efforts, aiming at one and the same thing, and can by no means be separated, or torn asunder, without at the same time leaving off the duties of their office. They are one, says he; in other words, they are so linked together, that their connection does not allow of any separation, because all ought to have one end in view, and they serve one Lord, and are engaged in the same work. Hence, if they employ themselves faithfully in cultivating the Lord’s field, they will maintain unity; and, by mutual communication, will help each other — so far from their names serving as standards to stir up contendings. Here we have a beautiful passage for exhorting ministers to concord. Meanwhile, however, he indirectly reproves those ambitious teachers, who, by giving occasion for contentions, discovered thereby that they were not the servants of Christ, but the slaves of vain-glory — that they did not employ themselves in planting and watering, but in rooting up and burning.
Every man will receive his own reward Here he shows what is the end that all ministers should have in view — not to catch the applause of the multitude, but to please the Lord. This, too, he does with the view of calling to the judgment-seat of God those ambitious teachers, who were intoxicated with the glory of the world, and thought of nothing else; and at the same time admonishing the Corinthians, as to the worthlessness of that empty applause which is drawn forth by elegance of expression and vain ostentation. He at the same time discovers in these words the fearlessness of his conscience, inasmuch as he ventures to look forward to the judgment of God without dismay. For the reason why ambitious men recommend themselves to the esteem of the world is, that they have not learned to devote themselves to God, and that they do not set before their eyes Christ’s heavenly kingdom. Accordingly, as soon as God comes to be seen, that foolish desire of gaining man’s favor disappears.
