For he that biddeth him God speed is partaker of his evil deeds.

People's New Testament

1:11 For he that biddeth him God speed is partaker of his evil deeds. He that gives him these prayerful greetings and encouragement becomes a partaker, to that extent, in his evil deeds.

Wesley's Notes

1:11 For he that biddeth him God speed - That gives him any encouragement, is accessory to his evil deeds.

Jamieson-Fausset-Brown Bible Commentary

11. 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.

Matthew Henry's Concise Commentary

1:7-11 The deceiver and his deceit are described: he brings some error concerning the person or office of the Lord Jesus. Such a one is a deceiver and an antichrist; he deludes souls, and undermines the glory and kingdom of the Lord Christ. Let us not think it strange, that there are deceivers and opposers of the Lord Christ's name and dignity now, for there were such, even in the apostles' times. The more deceivers and deceits abound, the more watchful the disciples must be. Sad it is, that splendid attainments in the school of Christ, should ever be lost. The way to gain the full reward is, to abide true to Christ, and constant in religion to the end. Firm cleaving to Christian truth unites us to Christ, and thereby to the Father also; for they are one. Let us equally disregard such as abide not in the doctrine of Christ, and those who transgress his commands. Any who did not profess and preach the doctrine of Christ, respecting him as the Son of God, and salvation by him from guilt and sin, were not to be noticed and countenanced. Yet in obeying this command, we must show kindness and a good spirit to those who differ from us in lesser matters, but hold firmly the all-important doctrines of Christ's person, atonement, and holy salvation.

Matthew Henry's Whole Bible Commentary

Verses 10-11

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!
