Matthew 16:13

Christ puts this question to His disciples, that from their answer we may learn that there were at that time among the Jews various opinions concerning Christ; and to the end that we should always investigate what opinion men may form of us; that if any ill be said of us, we may cut off the occasions of it; or if any good, we may multiply the occasions of it.

By asking, Whom do men say that the Son of Man is? He implied that something ought to be thought respecting Him beyond what appeared, for He was the Son of Man. And in thus enquiring after men's opinion respecting Himself, we are not to think that He made confession of Himself; for that which He asked for was something concealed, to which the faith of believers ought to extend itself. We must hold that form of confession, that we so mention the Son of God as not to forget the Son of Man, for the one without the other offers us no hope of salvation; and therefore He said emphatically, Whom do men say that the Son of Man is?

Wherefore hath he mentioned the founder of the city? Because there was another besides, Caesarea Stratonis. But not in that, but in this doth He ask them, leading them far away from the Jews, so that being freed from all alarm, they might speak with boldness all that was in their mind. And wherefore did He not ask them at once their own opinion, but that of the people? In order that when they had told the people's opinion, and then were asked, "But whom say ye that I am?" by the manner of His inquiry they might be led up to a sublimer notion, and not fall into the same low view as the multitude. Accordingly He asks them not at all in the beginning of His preaching, but when He had done many miracles, and had discoursed with them of many and high doctrines, and had afforded so many clear proofs of His Godhead, and of His unanimity with the Father, then He puts this question to them. And He said not, "Whom say the Scribes and Pharisees that I am?" often as these had come unto Him, and discoursed with Him; but, "Whom do men say that I am?" inquiring after the judgment of the people, as unbiassed. For though it was far meaner than it should be, yet was it free from malice, but the other was teeming with much wickedness. And signifying how earnestly He desires His Economy to be confessed, He saith, "The Son of Man;" thereby denoting His Godhead, which He doth also in many other places. For He saith, "No man hath ascended up to Heaven, but the Son of Man, which is in Heaven." And again, "But when ye shall see the Son of Man ascend up, where He was before."

This Philip was the brother of Herod, the tetrarch of Ituræa, and the region of Trachonitis, who gave to the city, which is now called Panæas, the name of Cæsarea in honour of Tiberius Cæsar. Beautifully is the question put, Whom do men say that the Son of Man is? For they who speak of the Son of Man, are men: but they who understood His divine nature are called not men but Gods. He says not, Whom, do men say that I am? but, Whom do men say that the Son of Man is? that He should not seem to ask ostentatiously concerning Himself. Observe, that wherever the Old Testament has 'Son of Man,' the phrase in the Hebrew is 'Son of Adam,'

He enquires the opinions of His disciples and of those without, not because He was ignorant of them; His disciples He asks, that He may reward with due reward their confession of a right faith, and the opinions of those without He enquires, that having the wrong opinions first set forth, it might be proved that the disciples had received the truth of their confession not from common opinion, but out of the hidden treasure of the Lord's revelation.
