II John 1:11

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.

The apostle here salutes an honourable matron and her children (Jo2 1:1-3). Recommends to them faith and love (Jo2 1:5, Jo2 1:6). Warns them of deceivers (Jo2 1:7), and to take heed to themselves (Jo2 1:8). Teaches how to treat those who bring not the doctrine of Christ (Jo2 1:10, Jo2 1:11). And, referring other things to personal discourse, concludes the epistle (Jo2 1:12, Jo2 1:13).
