2 John 1:10

“If there come any unto you, etc.] Under the character of a preacher; and bring not this doctrine; or does not preach the doctrine of Christ, as before explained, but despises it, and preaches a contrary one: receive him not into [your] house; neither into the house of God, suffer him not to preach there; nor into your own house, give him no entertainment there: false teachers always tried to creep into houses, where they served their own turn every way, both by feeding their bellies, and spreading their pernicious doctrines; and therefore such should: be avoided, both publicly and privately; their ministry should not be attended on in the church, or house of God; and they should not be…”

“If there come any--as a teacher or brother. The Greek is indicative, not subjunctive; implying that such persons do actually come, and are sure to come; when any comes, as there will. True love is combined with hearty renunciation and separation from all that is false, whether persons or doctrines. receive him not . . . neither bid him God speed--This is not said of those who were always aliens from the Church, but of those who wish to be esteemed brethren, and subvert the true doctrine [GROTIUS]. The greeting salutation forbidden in the case of such a one is that usual among Christian brethren in those days, not a mere formality, but a token of Christian brotherhood.”

“If there come any unto you - Any professed teacher of religion. There can be no doubt that she to whom this Epistle was written was accustomed to entertain such teachers.

“1:10-11 Believers should not invite that person, who does not teach the truth about Christ, into their homes. The early churches met in homes (see Acts 2:46; 5:42; 8:3; 12:5, 12; Col 4:15; Phlm 1:2), so this could refer to inviting false teachers to a meeting of the church. It could also refer to giving any form of hospitality to false teachers, which would help their mission. The only way to deal with them was to not accept them into the fellowship.”
