First Reading — Exodus 22:20-26
Clement of Alexandria
On 22:25
There is a great deal about sharing and exchanging, but it is enough to say that the law forbids lending at interest to a brother. By brother it means not merely one born of the same parents but a member of the same tribe or one of the same faith, who shares in the same Logos. The law does not deem it right to collect interest on the capital. It seeks to enable free giving to those in need, with hands and minds wide open. God is the creator of this free gift. It is he who shares his goods, exacting as the only reasonable interest the most precious things human beings possess: gentleness, goodness, high-mindedness, repute, glory.
Responsorial Psalm — Psalm 18:2-3, 3-4, 47, 51
Irenaeus
On 17:43
For [the word] "son," as one before me has observed, has a twofold meaning: one [is a son] in the order of nature, because he was born a son; the other, in that he was made so, is reputed a son, although there be a difference between being born so and being made so. For the first is indeed born from the person referred to; but the second is made so by him, whether as respects his creation or by the teaching of his doctrine. For when any person has been taught from the mouth of another, he is termed the son of him who instructs him, and the latter [is called] his father. According to nature, then -that is, according to creation, so to speak-we are all sons of God, because we have all been created by God. But with respect to obedience and doctrine we are not all the sons of God: those only are so who believe in Him and do His will. And those who do not believe, and do not obey His will, are sons and angels of the devil, because they do the works of the devil. And that such is the case He has declared in Isaiah: "I have begotten and brought up children, but they have rebelled against Me." And again, where He says that these children are aliens: "Strange children have lied unto Me." According to nature, then, they are [His] children, because they have been so created; but with regard to their works, they are not His children.
Second Reading — 1 Thessalonians 1:5c-10
Tertullian
On 1:9
Whence is proved that they have ever been depicted, out of the volume of the divine Scriptures, as guilty of the crime of idolatry; whereas our "less"-that is, posterior-people, quitting the idols which formerly it used slavishly to serve, has been converted to the same God from whom Israel, as we have above related, had departed. For thus has the "less"-that is, posterior-people overcome the"greater people," while it attains the grace of divine favour, from which Israel has been divorced.
On 1:9
For we read: "How ye turned from idols to serve the living and true God, and to wait for His Son from heaven, whom He raised from the dead, even Jesus." And again: "For what is our hope, or joy, or crown of rejoicing? Are not even ye in the presence of our Lord God, Jesus Christ, at His coming? " Likewise: "Before God, even our Father, at the coming of the Lord Jesus Christ, with the whole company of His saints.
Gospel — Matthew 22:34-40
Origen
On 22:34
Jesus had put the Sadducees to silence, to shew that the tongue of falsehood is silenced by the brightness of truth. For as it belongs to the righteous man to be silent when it is good to be silent, and to speak when it is good to speak, and not to hold his) peace; so it belongs to every teacher of a the Not indeed to be silent, but to be silent as far as any good purpose is concerned.
On 22:34
All who thus ask questions of any teacher to try him, and not to learn of him, we must regard as brethren of this Pharisee, according to what is said below, Inasmuch as ye have done it unto one of the least of mine, ye have done it unto me. (Matt. 25:40.)
On 22:34
Or otherwise; With all thy heart, that is, in all recollection, act, thought; with all thy soul, to be ready, that is, to lay it down for God’s religion; with all thy mind, bringing forth nothing but what is of God. And consider whether you cannot thus take the heart of the understanding, by which we contemplate things intellectual, and the mind of that by which we utter thoughts, walking as it were with the mind through each expression, and uttering it. If the Lord had given no answer to the Pharisee who thus tempted Him, we should have judged that there was no commandment greater than the rest. But when the Lord adds, This is the first and great commandment, we learn how we ought to think of the commandments, that there is a great one, and that there are less down to the least. And the Lord says not only that it is a great, but that it is the first commandment, not in order of Scripture, but in supremacy of value. They only take upon them the greatness and supremacy of this precept, who not only love the Lord their God, but add these three conditions. Nor did He only teach the first and great commandment, but added that there was a second like unto the first, Thou shall love thy neighbour as thyself. But if Whoso loveth iniquity hath hated his own soul, (Ps. 11:5.) it is manifest that he does not love his neighbour as himself, when he does not love himself.
On 22:36
He said Master tempting Him, for none but a disciple would thus address Christ. Whoever then does not learn of the Word, nor yields himself wholly up to it, yet calls it Master, he is brother to this Pharisee thus tempting Christ. Perhaps while they read the Law before the Saviour’s coming, it was a question among them which was the great commandment in it; nor would the Pharisee have asked this, if it had not been long time enquired among themselves, but never found till Jesus came and declared it.
On 22:40
Or, because he that has fulfilled the things that are written concerning the love of God and our neighbour, is worthy to receive from God the great reward, that he should be enabled to understand the Law and the Prophets.
