Who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some.
Ver. 18. Have erred] Gr. ηστοχησαν, have missed the mark, as unskilful archers, or as inconsiderate mariners, by misreckoning of a point, they have missed the haven and run upon the rocks.
That the resurrection is past] These were (likely) the progenitors of Marcion, who taught that there was no resurrection of the body to be believed, but of the soul only from sin. (Epiph. Haeres. 43.) This heresy is now revived among us, and raked again out of the grave; as many other also are and will be, by this lawless liberty.
And overthrow the faith of some.] Not the grace, but the profession of faith; and this they are ever doing at (the word, ανατρεπουσι is in the present tense), that they may undo their disciples; by digging at the foundation thus, that they may demolish the whole fabric.
