2 John 1:10 - Coke's Commentary on the Holy Bible

If there come any unto you,— If any one come unto you. Doddridge. Polycarp is said to have reported, that St. John, on going into the bath at Ephesus to washhimself,seeingCerinthusthere,he immediately hastened out of the bath; saying, "that he was afraid the bath should fall down, when Cerinthus, the enemy of truth, was there;"and Polycarp himself is reported to have treated Marcion with no more civility. Whence we may learn what caution the apostles made use of to avoid intercourse or commerce with those who adulterated the truth. The Jews were forbidden by their rabbis to say, "God speed" to, or to come within four cubits of, a heretic or excommunicated person. Our apostle, however, must not here be understood as excluding the common offices of humanity to such persons; for that is contrary to all the general precepts of benevolence found in the gospel: but, to have received a seducing teacher into their houses, and have given him suitable accommodations, would have been shewing him such regard, and affording him such countenance, as indeed in some measure would have made them answerable for the mischief he might do in the church; such favours being not merely offices of common humanity, but of patronage and friendship; and in the general, at least, a testimony of their approbation, as well as kindness. See 2 John 1:11.
