First Reading — Zechariah 9:9-10
Justin Martyr
On 9:9
"And that expression, 'binding his foal to the vine, and the ass's foal to the vine tendril,' was a declaring beforehand both of the works wrought by Him at His first advent, and also of that belief in Him which the nations would repose. For they were like an unharnessed foal, which was not bearing a yoke on its neck, until this Christ came, and sent His disciples to instruct them; and they bore the yoke of His word, and yielded the neck to endure all [hardships], for the sake of the good things promised by Himself, and expected by them. And truly our Lord Jesus Christ, when He intended to go into Jerusalem, requested His disciples to bring Him a certain ass, along with its foal, which was bound in an entrance of a village called Bethphage; and having seated Himself on it, He entered into Jerusalem. And as this was done by Him in the manner in which it was prophesied in precise terms that it would be done by the Christ, and as the fulfilment was recognised, it became a clear proof that He was the Christ. And though all this happened and is proved from Scripture, you are still hard-hearted. Nay, it was prophesied by Zechariah, one of the twelve [prophets], that such would take place, in the following words: 'Rejoice greatly, daughter of Zion; shout, and declare, daughter of Jerusalem; behold, thy King shall come to thee, righteous, bringing salvation, meek, and lowly, riding on an ass, and the foal of an ass.' Now, that the Spirit of prophecy, as well as the patriarch Jacob, mentioned both an ass and its foal, which would be used by Him; and, further, that He, as I previously said, requested His disciples to bring both beasts; [this fact] was a prediction that you of the synagogue, along with the Gentiles, would believe in Him. For as the unharnessed colt was a symbol of the Gentiles even so the harnessed ass was a symbol of your nation. For you possess the law which was imposed [upon you] by the prophets."
Responsorial Psalm — Psalm 145:1-2, 8-9, 10-11, 13-14
Gregory of Nyssa
On 144:3
Now if any one should ask for some interpretation, description and explanation of the divine essence, we are not going to deny that we are unlearned in this kind of wisdom, acknowledging only so much as this, that it is not possible that which is by nature infinite should be comprehended in any conception expressed by words. The fact that the divine greatness has no limit is proclaimed by prophecy, which declares expressly that of his splendor, his glory and his holiness, "there is no end." If his surroundings have no limit, much more is he himself in his essence, whatever it may be, comprehended by no limitation in any way. If then interpretation by way of words and names implies by its meaning some sort of comprehension of the subject, and if, on the other hand, that which is unlimited cannot be comprehended, no one could reasonably blame us for ignorance, if we are not bold in respect of what none should venture on. For by what name can I describe the incomprehensible? By what speech can I declare the unspeakable? Accordingly, since the Deity is too excellent and lofty to be expressed in words, we have learned to honor in silence what transcends speech and thought. If he who "thinks more highly than he ought to think" tramples on this cautious speech of ours making a jest of our ignorance of things incomprehensible, and recognizes a difference of unlikeness in that which is without figure, or limit, or size or quantity (I mean in the Father, the Son and the Holy Spirit) and brings forward to reproach our ignorance that phrase that is continually alleged by the disciples of deceit, " 'You worship you know not what,' if you know not the essence of that which you worship," we shall follow the advice of the prophet. We shall not fear the reproach of fools or be led by their reviling to talk boldly of things unspeakable. That unpracticed speaker Paul we make our teacher in the mysteries that transcend knowledge. He is so far from thinking that the divine nature is within the reach of human perception that he calls even the judgments of God "unsearchable" and his ways "past finding out." He affirms that the things promised to them that love him, for their good deeds done in this life, are above comprehension so that it is not possible to behold them with the eye, or to receive them by hearing or to contain them in the heart.
On 144:3
Instead of speaking of him [God the Father] as "ungenerated," it is permissible to call him the "First Cause" or "Father of the Only-Begotten," or to speak of him as "existing without cause," and many such expressions that lead to the same thought. In that case Eunomius confirms our doctrines by the very arguments in which he brings charges that we do not know any name indicative of the divine nature. We are taught the fact of its existence, while we assert that a name of such breath as to include the unspeakable and infinite nature either does not exist at all or at any rate is unknown to us. Let him then abandon his usual fictive language, and show us the names that signify the real meanings and then proceed further to divide the subject by the divergence of their names. But as long as the statement of the Scripture is correct that Abraham and Moses were not capable of the knowledge of the name, and that "no one has seen God at any time," and that "no one has seen him, nor can see," and that the light around him is unapproachable and "there is no end of his greatness," so long can we say and believe these things. This is similar to an argument that promises any comprehension and expression of the infinite nature by means of the meaning of names to one who thinks that he can enclose the whole sea in his own hand! Just as the hollow of one's hand is comparable to the entire depth of the sea, so is all the power of language comparable to that nature that is unspeakable and incomprehensible.
Second Reading — Romans 8:9, 11-13
Polycarp of Smyrna
On 8:11
"Wherefore, girding up your loins," "serve the Lord in fear" and truth, as those who have forsaken the vain, empty talk and error of the multitude, and "believed in Him who raised up our Lord Jesus Christ from the dead, and gave Him glory," and a throne at His right hand. To Him all things in heaven and on earth are subject. Him every spirit serves. He comes as the Judge of the living and the dead. His blood will God require of those who do not believe in Him. But He who raised Him up from the dead will raise up us also, if we do His will, and walk in His commandments, and love what He loved, keeping ourselves from all unrighteousness, covetousness, love of money, evil speaking, false witness; "not rendering evil for evil, or railing for railing," or blow for blow, or cursing for cursing, but being mindful of what the Lord said in His teaching: "Judge not, that ye be not judged; forgive, and it shall be forgiven unto you; be merciful, that ye may obtain mercy; with what measure ye mete, it shall be measured to you again;" and once more, "Blessed are the poor, and those that are persecuted for righteousness' sake, for theirs is the kingdom of God."
Gospel — Matthew 11:25-30
Hilary of Poitiers
On 11:25
The hidden things of heavenly words and their power are hid from the wise, and revealed to the babes; babes, that is, in malice, not in understanding; hid from the wise because of their presumption of their own wisdom, not because of their wisdom.
On 11:25
The justice of this the Lord confirms by the sentence of the Father’s will, that they who disdain to be made babes in God, should become fools in their own wisdom; and therefore He adds, Even so, Father; for so it seemed good before thee.
On 11:27
Or that we may not think that there is any thing less in Him than in God, therefore He says this.
On 11:27
And also in the mutual knowledge between the Father and the Son, He teaches us that there is nothing in the Son beyond what was in the Father, for it follows, And none knoweth the Son but the Father, nor does any man know the Father but the Son.
On 11:27
For this mutual knowledge proclaims that they are of one substance, since He that should know the Son, should know the Father also in the Son, since all things were delivered to Him by the Father.
On 11:28
He calls to Him those that were labouring under the hardships of the Law, and those who are burdened with the sins of this world.
On 11:28
He holds forth the inducements of a pleasant yoke, and a light burden, that to them that believe He may afford the knowledge of that good which He alone knoweth in the Father.
On 11:28
And what is more pleasant than that yoke, what lighter than that burden? To be made better, to abstain from wickedness, to choose the good, and refuse the evil, to love all men, to hate none, to gain eternal things, not to be taken with things present, to be unwilling to do that to another which yourself would be pained to suffer.
