For in calling him his dearly beloved son, he intimates that he knew him intimately, and was acquainted with all his affairs; and farther, he speaks of him as faithful in the Lord He gives also two things in charge to Timothy — first, to recall to the recollection of the Corinthians those things which they should of themselves have had in remembrance, and in this he tacitly reproves them; and secondly, to testify to them, how uniform and steady his manner of teaching was in every place. Now it is probable that he had been assailed by the calumnies of the false apostles, as though he assumed more authority over the Corinthians than he did over others, or as though he conducted himself in a very different way in other places; for it is not without good reason that he wishes this to be testified to them.
