18. And it came to pass, as he was alone praying, his disciples were with him: and he asked them, saying, Whom say the people that I am?
19. They answering said, John the Baptist; but some say, Elias; and others say, that one of the old prophets is risen again.
20. He said to them, But whom say you that I am? Peter answering said, The Christ of God.
21. And he straitly charged them, and commanded them to tell no man that thing;
22. Saying, The Son of man must suffer many things, and be rejected of the elders and Chief Priests and Scribes, and be slain, and be raised the third day.
CYRIL; Our Lord having retired from the multitude, and being in a place apart, was engaged in prayer. As it is said, And it came to pass, as he was alone praying. For He ordained Himself as an example of this, instructing His disciples by an easy' method of teaching. For I suppose the rulers of the people ought to be superior also in good deeds, to those that are under them, ever holding converse with them in all necessary things, and treating of those things in which God delights.
THEOPHYL; Now the disciples were with the Lord, but He alone prayed to the Father, since the saints may be joined to the Lord in the bond of faith and love, but the Son alone is able to penetrate the incomprehensible secrets of the Father's will. Every where then He prays alone, for human wishes comprehend not the counsel of God, nor can any one be a partaker with Christ of the deep things of God.
CYRIL; Now His engaging in prayer might perplex His disciples. For they saw Him praying like a man, Whom before they had seen performing miracles with divine power. In order then to banish all perplexity of this kind, He asks them this question, not because He did not know the reports which they had gathered from without, but that He might rid them of the opinion of the many, and instill into them the true faith. Hence it follows, And he asked them, saying, Whom say the people that I am?
THEOPHYL; Rightly does our Lord, when about to inquire into the faith of the disciples, first inquire into the opinion of the multitudes, lest their confession should appear not to be determined by their knowledge, but to be formed by the opinion of the generality, and they should be considered not to believe from experience, but like Herod to be perplexed by different reports which they heard.
AUG. Now it may raise a question, that Luke says that our Lord asked His disciples, Whom do men say that I am? at the same time that He was alone praying, and they also were with Him; whereas Mark says, that they were asked this question by our Lord on the way; but this is difficult only to him who never prayed on the way.
AMBROSE; But it is no trifling opinion of the multitude which the disciples mention, when it is added, But they answering said, John the Baptist, (whom they knew to be beheaded;) but some say, Elias, (whom they thought would come,) but others say that one of the old Prophets is risen again. But to make this inquiry belongs to a different kind of wisdom from ours, for if it were enough for the Apostle Paul to know nothing but Christ Jesus, and Him crucified, what more can I desire to know than Christ?
CYRIL; But mark the subtle skill of the question. For he directs them first to the praises of strangers, that having overthrown these, He might beget in them the right opinion. So when the disciples had given the opinion of the people, He asks them their own opinion; as it is added, And He said to them, Whom say you that I am? How marked is you! He excludes them from the other, that they may avoid their opinions; as if He said, you who by my decree are called to the Apostleship, the witnesses of my miracles, whom do you say that I am? But Peter anticipated the rest, and becomes the mouthpiece of the whole company, and launching forth into the eloquence of divine love, utters the confession of faith, as it is added, Peter answering said, The Christ of God. He says not merely that He was Christ of God, but now He uses the article. Hence it is in the Greek. For many divinely accounted persons are in diverse ways called Christs, for some were anointed kings, some prophets. But we through Christ have been anointed by the holy Spirit, have obtained the name of Christ. But there is only one who is the Christ of God and the Father, He alone as it were having His own Father who is in heaven. And so Luke agrees indeed in the same opinion as Matthew, who relates Peter to have said, You are Christ, the Son of the living God, but speaking briefly Luke says that Peter answered, the Christ of God.
AMBROSE; In this one name there is the expression both of His divinity and incarnation, and the belief of His passion. He has therefore comprehended every thing, having expressed both the nature and tile name wherein is all virtue.
CYRIL; But we must observe, that Peter most wisely confessed Christ to be one, against those who presumed to divide Immanuel into two Christs. For Christ did not inquire of them, saying, Whom do men say the divine Word is? but the Son of man, whom Peter confessed to be the Son of God. Herein then is Peter to be admired, and thought worthy of such chief honor, seeing that Him whom he marveled at in our form, he believed to be the Christ of the Father, that is to say, that the Word which proceeded of the Father's Substance was become man.
AMBROSE; But our Lord Jesus Christ was as at first unwilling to be preached, lest an uproar should arise; as it follows, And he straitly charged them, and commanded them to tell no man any thing. For many reasons He commands His disciples to be silent; to deceive the prince of this world, to reject boasting, to teach humility. Christ then would not boast, and cost you boast who are of ignoble birth? Likewise He did it to prevent rude and as yet imperfect disciples from being oppressed with the wonder of this awful announcement. They are then forbid to preach Him as the Son of God, that they might afterwards preach Him crucified.
CHRYS. Timely also was our Lord's command that no one should tell that He was Christ, in order that when offenses should be taken away and the sufferings of the cross completed, a proper opinion of Him might be firmly rooted in the minds of the hearers. For that which has once taken root and afterwards been torn up, when fresh planted will scarcely ever be preserved. But that which when once planted continues undisturbed, grows up securely. For if Peter was offended merely by what he heard, what would be the feelings of those many who, after they had heard that He was the Son of God, saw Him crucified, and spit upon?
CYRIL; It was the duty then of the disciples to preach Him throughout the world. For this was the work of those who were chosen by Him to the office of the Apostleship. But as holy Scripture bears witness, There is a time for every thing. For it was fitting that the cross and resurrection should be accomplished, an d then should follow the preaching of the Apostles; as it is spoken, saying, The Son of man must needs suffer many things.
AMBROSE; Perhaps because the Lord knew that the disciples would believe even the difficult mystery of the Passion and Resurrection, He wished to be Himself the proclaimer of His own Passion and Resurrection.
