First Reading — Romans 11:29-36
Irenaeus
On 11:32
This, therefore, was the [object of the] long-suffering of God, that man, passing through all things, and acquiring the knowledge of moral discipline, then attaining to the resurrection from the dead, and learning by experience what is the source of his deliverance, may always live in a state of gratitude to the Lord, having obtained from Him the gift of incorruptibility, that he might love Him the more; for "he to whom more is forgiven, loveth more:" and that he may know himself, how mortal and weak he is; while he also understands respecting God, that He is immortal and powerful to such a degree as to confer immortality upon what is mortal, and eternity upon what is temporal; and may understand also the other attributes of God displayed towards himself, by means of which being instructed he may think of God in accordance with the divine greatness. For the glory of man [is] God, but [His] works [are the glory] of God; and the receptacle of all His wisdom and power [is] man. Just as the physician is proved by his patients, so is God also revealed through men. And therefore Paul declares, "For God hath concluded all in unbelief, that He may have mercy upon all;" not saying this in reference to spiritual Aeons, but to man, who had been disobedient to God, and being cast off from immortality, then obtained mercy, receiving through the Son of God that adoption which is [accomplished] by Himself. For he who holds, without pride and boasting, the true glory (opinion) regarding created things and the Creator, who is the Almighty God of all, and who has granted existence to all; [such an one, ] continuing in His love and subjection, and giving of thanks, shall also receive from Him the greater glory of promotion, looking forward to the time when he shall become like Him who died for him, for He, too, "was made in the likeness of sinful flesh," to condemn sin, and to cast it, as now a condemned thing, away beyond the flesh, but that He might call man forth into His own likeness, assigning him as [His own] imitator to God, and imposing on him His Father's law, in order that he may see God, and granting him power to receive the Father; [being] the Word of God who dwelt in man, and became the Son of man, that He might accustom man to receive God, and God to dwell in man, according to the good pleasure of the Father.
On 11:33
It does not follow because men are endowed with greater and less degrees of intelligence, that they should therefore change the subject-matter [of the faith] itself, and should conceive of some other God besides Him who is the Framer, Maker, and Preserver of this universe, (as if He were not sufficient for them), or of another Christ, or another Only-begotten. But the fact referred to simply implies this, that one may [more accurately than another] bring out the meaning of those things which have been spoken in parables, and accommodate them to the general scheme of the faith; and explain [with special clearness] the operation and dispensation of God connected with human salvation; and show that God manifested longsuffering in regard to the apostasy of the angels who transgressed, as also with respect to the disobedience of men; and set forth why it is that one and the same God has made some things temporal and some eternal, some heavenly and others earthly; and understand for what reason God, though invisible, manifested Himself to the prophets not under one form, but differently to different individuals; and show why it was that more covenants than one were given to mankind; and teach what was the special character of each of these covenants; and search out for what reason "God hath concluded every man in unbelief, that He may have mercy upon all;" and gratefully describe on what account the Word of God became flesh and suffered; and relate why the advent of the Son of God took place in these last times, that is, in the end, rather than in the beginning [of the world]; and unfold what is contained in the Scriptures concerning the end [itself], and things to come; and not be silent as to how it is that God has made the Gentiles, whose salvation was despaired of, fellow-heirs, and of the same body, and partakers with the saints; and discourse how it is that "this mortal body shall put on immortality, and this corruptible shall put on incorruption;" and proclaim in what sense [God] says, "That is a people who was not a people; and she is beloved who was not beloved;" and in what sense He says that "more are the children of her that was desolate, than of her who possessed a husband." For in reference to these points, and others of a like nature, the apostle exclaims: "Oh! the depth of the riches both of the wisdom and knowledge of God; how unsearchable are His judgments, and His ways past finding out!" But [the superior skill spoken of] is not found in this, that any one should, beyond the Creator and Framer [of the world], conceive of the Enthymesis of an erring Aeon, their mother and his, and should thus proceed to such a pitch of blasphemy; nor does it consist in this, that he should again falsely imagine, as being above this [fancied being], a Pleroma at one time supposed to contain thirty, and at another time an innumerable tribe of Aeons, as these teachers who are destitute of truly divine wisdom maintain; while the Catholic Church possesses one and the same faith throughout the whole world, as we have already said.
On 11:34
For in no other way could we have learned the things of God, unless our Master, existing as the Word, had become man. For no other being had the power of revealing to us the things of the Father, except His own proper Word. For what other person "knew the mind of the Lord," or who else "has become His counsellor?" Again, we could have learned in no other way than by seeing our Teacher, and hearing His voice with our own ears, that, having become imitators of His works as well as doers of His words, we may have communion with Him, receiving increase from the perfect One, and from Him who is prior to all creation.
On 11:36
They moreover affirm that the Saviour is shown to be derived from all the Aeons, and to be in Himself everything by the following passage: "Every male that openeth the womb." For He, being everything, opened the womb of the enthymesis of the suffering Aeon, when it had been expelled from the Pleroma. This they also style the second Ogdoad, of which we shall speak presently. And they state that it was clearly on this account that Paul said, "And He Himself is all things;" and again, "All things are to Him, and of Him are all things;" and further, "In Him dwelleth all the fulness of the Godhead;" and yet again, "All things are gathered together by God in Christ." Thus do they interpret these and any like passages to be found in Scripture.
Responsorial Psalm — Psalm 69:30-31, 33-34, 36
Clement of Rome
On 68:30–32
Brothers, the Lord of the universe has need of nothing; he requires nothing of anyone, except that confession be made to him. For David, the chosen one, says, "I will confess to the Lord, and it shall please him more than a young bullock with horns and hoofs. Let the poor see it and be glad." And again he says, "Sacrifice to God a sacrifice of praise, and render to the All-High your vows; and call on me in the day of affliction, and I will deliver you, and you shall glorify me." "For a contrite spirit is a sacrifice to God."
Gospel — Luke 14:12-14
Origen
On 14:13
But mystically, he who shuns vain-glory calls to a spiritual banquet the poor, that is, the ignorant, that he may enrich them; the weak, that is, those with offended consciences, that he may heal them; the lame, that is, those who have wandered from reason, that he may make their paths straight; the blind, that is, those who discern not the truth, that they may behold the true light. But it is said, They cannot recompense thee, i. e. they know not how to return an answer.
