As I exhorted you to stay at Ephesus when I was going into Macedonia, that you might charge certain men not to teach a different doctrine,
Not to teach a different doctrine ...  The false doctrine in evidence here "seems to have arisen mainly, if not entirely, from Jewish sources."[15] Apparently, some new phases of Jewish error had surfaced at Ephesus, indicating the passage of some time, intervening between this and Paul's earlier letters; but there is absolutely no indication that some remote later period in the late first or early second centuries is in view. The only thing proved by this is that "Paul's forebodings for the church in Ephesus (Acts 20:29,30) were at that time being fulfilled."[16] Wesley's quaint interpretation here is, "Let them put nothing in the place of it (the gospel), and add nothing to it."[17]
