Here, I. Upon due warning given concerning seducers, the apostle gives direction concerning the treatment of such. They are not to be entertained as the ministers of Christ. The Lord Christ will distinguish them from such, and so would he have his disciples. The direction is negative. 1. "Support them not: If there come any unto you, and bring not this doctrine (concerning Christ as the Son of God, the Messiah and anointed of God for our redemption and salvation), receive him not into your house." Possibly this lady was like Gaius, of whom we read in the next epistle, a generous housekeeper, and hospitable entertainer of travelling ministers and Christians. These deceivers might possibly expect the same reception with others, or with the best who came there (as the blind are often bold enough), but the apostle allows it not: "Do not welcome them into your family." Doubtless such may be relieved in their pressing necessities, but not encouraged for ill service. Deniers of the faith are destroyers of souls; and it is supposed that even ladies themselves should have good understanding in the affairs of religion. 2. "Bless not their enterprises: Neither bid him God speed. Attend not their service with your prayers and good wishes." Bad work should not be consecrated or recommended to the divine benediction. God will be no patron of falsehood, seduction, and sin. We ought to bid God speed to evangelical ministration; but the propagation of fatal error, if we cannot prevent, we must not dare to countenance. Then,

II.Here is the reason of such direction, forbidding the support and patronage of the deceiver: For he that biddeth him God speed is partaker of his evil deeds. Favour and affection partake of the sin. We may be sharers in the iniquities of others. How judicious and how cautious should the Christian be! There are many ways of sharing the guilt of other people's transgressions; it may be done by culpable silence, indolence, unconcernedness, private contribution, public countenance and assistance, inward approbation, open apology and defence. The Lord pardon our guilt of other persons' sins!

Is partaker of his evil deeds - He that acts towards him as if he considered him a Christian brother, and sound in the faith, puts it in his power to deceive others, by thus apparently accrediting his ministry. No sound Christian should countenance any man as a Gospel minister, who holds and preaches erroneous doctrines; especially concerning the Lord Jesus. Nor can any Christian attend the ministry of such teachers without being criminal in the sight of God. He who attends their ministry is, in effect, bidding them God speed; no matter whether such belong to an established Church, or to any congregation of dissenters from it. But what St. John says here does not mean that we should deny such the common offices of humanity, charity, and mercy. No. In these offices we are equally bound to all men; far less does it intimate that we should persecute such on account of their heretical or heterodox sentiments. No. This right has God given to no man, to no Church, to no state. They who persecute others, even for the worst heretical opinions, may expect the heaviest judgments of Almighty God.

There is a remarkable addition here in several MSS. Of the Vulgate, and in some printed editions. Ecce praedixi vobis, ut in diem Domini nostri Jesu Christi non confundamini. "Behold, I have foretold this to you, that ye may not be confounded in the day of our Lord Jesus Christ."

This addition is found in the edition of Pope Sixtus the Fifth, and in the Complutensian Polyglot; but it is not acknowledged by any of the versions, nor by any Greek MSS.

For he that biddeth him God speed,.... Wishes him well, and success in his ministry, or in a friendly and familiar way converses with him:

is partaker of his evil deeds; he has fellowship with him, instead of reproving or shunning him, as he ought; he is an abettor of him in his principles, and so far joins in the propagation of them, and helps to spread them, and gives too much reason to think he is one with him in them.

By wishing a false brother or teacher "God (or 'good') speed," you imply that he is capable as such of good speed and joy (the literal meaning of the Greek), and that you wish him it while opposing Christ; so you identify yourself with "his evil deeds." The Greek of "partaker" is "having communion with." We cannot have communion with saints and with Antichrist at the same time. Here we see John's naturally fiery zeal directed to a right end. POLYCARP, the disciple of John, told contemporaries of IRENÆUS, who narrates the story on their authority, that on one occasion when John was about to bathe, and heard that Cerinthus, the heretic, was within, he retired with abhorrence, exclaiming, Surely the house will fall in ruins since the enemy of the truth is there.
