Galatians 4:16

Your enemy. — “The enemy” was the name by which St. Paul was commonly referred to by the party hostile to him in the next century. It is quite possible that the phrase “your enemy” ought to be placed, as it wore, in inverted commas, and attributed to the Judaising sectaries — ”your enemy,” as these false teachers call me.

Because I tell you the truth. — It would seem that something had happened upon St. Paul’s second visit to Galatia (the visit recorded in Acts 18:23) which had caused a change in their feelings towards him. His plain speaking had given offence.
