Matt. XXII. 34-36.
“But when the Pharisees had heard that He had put the Sadducees to silence, they were gathered together; and one of them, which was a lawyer, asked Him a question, tempting Him, and saying, Master, which is the great commandment in the law?”
Again does the evangelist express the cause, for which they ought to have held their peace, and marks their boldness by this also. How and in what way? Because when those others were put to silence, these again assail Him. For when they ought even for this to hold their peace, they strive to urge further their former endeavors, and put forward the lawyer, not desiring to learn, but making a trial of Him, and ask, “What is the first commandment?”
For since the first commandment was this, “You shall love the Lord your God,” thinking that He would afford them some handle, as though He would amend it, for the sake of showing that Himself too was God, they propose the question. What then says Christ? Indicating from what they were led to this; from having no charity, from pining with envy, from being seized by jealousy, He says, “You shall love the Lord your God. This is the first and great commandment. And the second is like this, You shall love your neighbor as yourself.”
But wherefore “like this?” Because this makes the way for that, and by it is again established; “For every one that does evil hates the light, neither comes to the light;” and again, “The fool has said in his heart, There is no God.” And what in consequence of this? “They are corrupt, and become abominable in their ways.” And again, “The love of money is the root of all evils; which while some coveted after they have erred from the faith;” and, “He that loves me, will keep my commandment.”
But His commandments, and the sum of them, are, “You shall love the Lord your God, and your neighbor as yourself.” If therefore to love God is to love one's neighbor, “For if you love me,” He says, “O Peter, feed my sheep,” but to love one's neighbor works a keeping of the commandments, with reason does He say, “On these hang all the law and the prophets.”
So therefore what He did before, this He does here also. I mean, that both there, when asked about the manner of the resurrection, He also taught a resurrection, instruct ing them beyond what they inquired; and here, being asked the first commandment, He rehearses the second also, which is not much inferior to that (for though second, it is like that), intimating to them, whence the question had arisen, that it was from hatred. “For charity envies not.” By this He shows Himself to be submissive both to the law and to the prophets.
But wherefore does Matthew say that he asked, tempting Him, but Mark the contrary? “For when Jesus,” he says, “saw that he answered discreetly, He said unto him, You are not far from the kingdom of God.”
They are not contradicting each other, but indeed fully agreeing. For he asked indeed, tempting, at the beginning, but being benefitted by the answer, was commended. For not at the beginning did He commend him, but when he had said, “That to love his neighbor is more than whole burnt sacrifices,” then He says, “You are not far from the kingdom;” because he overlooked low things, and embraced the first principle of virtue. For indeed all those are for the sake of this, as well the Sabbath as the rest.
And not even so did He make His commendation perfect, but yet deficient. For His saying, “You are not far off,” indicates that he is yet falling short, that he might seek after what was deficient.
But if, when He said, “There is one God, and there is none other but He,” He commended him, wonder not, but by this too observe, how He answers according to the opinion of them that come unto Him. For although men say ten thousand things about Christ unworthy of His glory, yet this at any rate they will not dare to say, that He is not God at all. Wherefore then does He praise him that said, that beside the Father, there is no other God?
Not excepting Himself from being God; away with the thought; but since it was not yet time to disclose His Godhead, He suffers him to remain in the former doctrine, and praises him for knowing well the ancient principles, so as to make him fit for the doctrine of the New Testament, which He is bringing in its season.
And besides, the saying, “There is one God, and there is none other but He,” both in the Old Testament and everywhere, is spoken not to the rejection of the Son, but to make the distinction from idols. So that when praising this man also, who had thus spoken, He praises him in this mind.
Then since He had answered, He asks also in turn, “What think ye of Christ, whose Son is He? They say unto Him, The Son of David.”
See after how many miracles, after how many signs, after how many questions, after how great a display of His unanimity with the Father, as well in words, as in deeds; after having praised this man that said, that there is one God, He asks the question, that they may not be able to say, that He did miracles indeed, yet was an adversary to the law, and a foe to God.
Therefore, after so many things, He asks these questions, secretly leading them on to confess Him also to be God. And the disciples He asked first what the others say, and then themselves; but these not so; for surely they would have said a deceiver, and a wicked one, as speaking all things without fear. So for this cause He inquires for the opinion of these men themselves.
For since He was now about to go on to His passion, He sees forth the prophecy that plainly proclaims Him to be Lord; and not as having come to do this without occasion, nor as having made this His aim, but from a reasonable cause.
For having asked them first, since they answered not the truth concerning Him (for they said He was a mere man), to overthrow their mistaken opinion, He thus introduces David proclaiming His Godhead. For they indeed supposed that He was a mere man, wherefore also they said, “the Son of David;” but He to correct this brings in the prophet witnessing to His being Lord, and the genuineness of His Sonship, and His equality in honor with His Father.
And not even at this does He stop, but in order to move them to fear, He adds what follows also, saying, “Till I make Your enemies Your footstool;” that at least in this way He might gain them over.
And that they may not say, that it was in flattery he so called Him, and that this was a human judgment, see what He says, “How then does David in spirit call Him Lord?” See how submissively He introduces the sentence and judgment concerning Himself. First, He had said, “What do you think? Whose Son is He?” so by a question to bring them to an answer. Then since they said, “the Son of David,” He said not, “And yet David says these things,” but again in this order of a question, “How then does David in spirit call Him Lord?” in order that the sayings might not give offense to them. Wherefore neither did He say, What think ye of me, but of Christ. For this reason the apostles also reasoned submissively, saying, “Let us speak freely of the Patriarch David, that he is both dead and buried.”
And He Himself too in like manner for this cause introduces the doctrine in the way of question and inference, saying, “How then does David in spirit call Him Lord, saying, The Lord said unto my Lord, Sit on my right hand, until I make Your foes Your footstool;” and again, “If David then call Him Lord, how is He then his Son,” not taking away the fact that He is his Son, away with the thought; for He would not then have reproved Peter for this, but to correct their secret thoughts. So that when He says, “How is He his Son?” He means this, not so as you say. For they said, that He is Son only, and not also Lord. And this after the testimony, and then submissively, “If David then call Him Lord, how is He his Son?”
