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!
