First Reading — Jeremiah 23:1-6
Leo the Great
On 23:5–6
There was only one remedy in the secret of the divine plan that could help the fallen living in the general ruin of the entire human race. This remedy was that one of the sons of Adam should be born free and innocent of original transgression, to prevail for the rest by his example and by his merits. This was not permitted by natural generation. There could be no clean offspring from our faulty stock by this seed. The Scripture says, "Who can make a clean thing conceived of an unclean seed? Isn't it you alone?" David's Lord was made David's Son, and from the fruit of the promised branch sprang. He is one without fault, the twofold nature coming together into one person. By this one and the same conception and birth sprung our Lord Jesus Christ, in whom was present both true Godhead for the performance of mighty works and true manhood for the endurance of sufferings.
Responsorial Psalm — Psalm 23:1-3, 3-4, 5, 6
Hippolytus of Rome
On 22:1
And, moreover, the ark made of imperishable wood was the Saviour Himself. For by this was signified the imperishable and incorruptible tabernacle of (the Lord) Himself, which gendered no corruption of sin. For the sinner, indeed, makes this confession: "My wounds stank, and were corrupt, because of my foolishness." But the Lord was without sin, made of imperishable wood, as regards His humanity; that is, of the virgin and the Holy Ghost inwardly, and outwardly of the word of God, like an ark overlaid with purest gold.
Second Reading — Ephesians 2:13-18
Irenaeus
On 2:13
And everywhere, when [referring to] the passion of our Lord, and to His human nature, and His subjection to death, he employs the name of Christ, as in that passage: "Destroy not him with thy meat for whom Christ died." And again: "But now, in Christ, ye who sometimes were far off are made nigh by the blood of Christ." And again: "Christ has redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth upon a tree." And again: "And through thy knowledge shall the weak brother perish, for whom Christ died; " indicating that the impassible Christ did not descend upon Jesus, but that He Himself, because He was Jesus Christ, suffered for us; He, who lay in the tomb, and rose again, who descended and ascended,-the Son of God having been made the Son of man, as the very name itself doth declare. For in the name of Christ is implied, He that anoints, He that is anointed, and the unction itself with which He is anointed. And it is the Father who anoints, but the Son who is anointed by the Spirit, who is the unction, as the Word declares by Isaiah, "The Spirit of the Lord is upon me, because He hath anointed me," -pointing out both the anointing Father, the anointed Son, and the unction, which is the Spirit.
On 2:13
If, then, any one allege that in this respect the flesh of the Lord was different from ours, because it indeed did not commit sin, neither was deceit found in His soul, while we, on the other hand, are sinners, he says what is the fact. But if he pretends that the Lord possessed another substance of flesh, the sayings respecting reconciliation will not agree with that man. For that thing is reconciled which had formerly been in enmity. Now, if the Lord had taken flesh from another substance, He would not, by so doing, have reconciled that one to God which had become inimical through transgression. But now, by means of communion with Himself, the Lord has reconciled man to God the Father, in reconciling us to Himself by the body of His own flesh, and redeeming us by His own blood, as the apostle says to the Ephesians, "In whom we have redemption through His blood, the remission of sins; " and again to the same he says, "Ye who formerly were far off have been brought near in the blood of Christ; " and again, "Abolishing in His flesh the enmities, [even] the law of commandments [contained] in ordinances." And in every Epistle the apostle plainly testifies, that through the flesh of our Lord, and through His blood, we have been saved.

On 2:17
This is also made clear from the words of the Lord, who did truly reveal the Son of God to those of the circumcision-Him who had been foretold as Christ by the prophets; that is, He set Himself forth, who had restored liberty to men, and bestowed on them the inheritance of incorruption. And again, the apostles taught the Gentiles that they should leave vain stocks and stones, which they imagined to be gods, and worship the true God, who had created and made all the human family, and, by means of His creation, did nourish, increase, strengthen, and preserve them in being; and that they might look for His Son Jesus Christ, who redeemed us from apostasy with His own blood, so that we should also be a sanctified people,-who shall also descend from heaven in His Father's power, and pass judgment upon all, and who shall freely give the good things of God to those who shall have kept His commandments. He, appearing in these last times, the chief cornerstone, has gathered into one, and united those that were far off and those that were near; that is, the circumcision and the uncircumcision, enlarging Japhet, and placing him in the dwelling of Shem.
Gospel — Mark 6:30-34
Augustine of Hippo
On 6:30
(de Con. Evan. 2. 45) This is said to have taken place, after the passion of John, therefore what is first related took place last, for it was by these events that Herod was moved to say, This is John the Baptist, whom I beheaded.
