First Reading — Hebrews 3:7-14
Cyril of Jerusalem
On 3:13
Take also another like expression. "To this day whenever Moses is read a veil lies over their minds." Does "to this day" mean "up to the time that Paul wrote the words and no longer"? Does it not mean until this present day and indeed to the very end? And if Paul should say, "We are come all the way to you with the gospel of Christ, having hope, when your faith is increased, to preach the gospel in lands beyond you," you can see clearly that the phrase "all the way" sets no limit but indicates what lies beyond. With what meaning, therefore, ought you to recall the words "till he has put all enemies"? Just the same as in another saying of Paul, "But exhort each other daily, as long as it is called 'today,' " which clearly means for all time. For as we must not talk of a beginning of the days of Christ, so never suffer anyone to speak of an end of his kingdom. For Scripture says, "his kingdom is an everlasting kingdom."
On 3:13
"Give us this day our superessential bread." Ordinary bread is not "superessential," but this holy bread is superessential in the sense of being ordained for the essence of the soul. Not of this bread is it said that it "passes into the stomach and is discharged into the drain." No, it is absorbed into your whole system to the benefit of both soul and body. By "this day" he means "daily," as in Paul's "while it is called 'today.' "
Responsorial Psalm — Psalm 95:6-7c, 8-9, 10-11
Ambrose of Milan
On 94:10–11
"See, O people, the grace of Christ about you. Even while you are harassed on earth, you have possessions in heaven. There, then, let your heart be, where your possession is." This is the rest that is due the just and is denied the unworthy. Wherefore says the Lord, "As I swore in my wrath, that they shall not enter into my rest." For they who have not known the ways of the Lord shall not enter into the rest of the Lord, but to the individual who has fought the good fight and has finished his course it is said, "Turn to your rest." It is a blessed rest to pass by the things of the world and to find repose in the celestial fellowship of the mysteries that are above the world. This is the rest toward which the prophet hastened, saying, "Who will give me wings like a dove and I will fly and be at rest?" The holy person knows that his rest is in heaven, and to this rest he says his soul must turn. Therefore his soul was in its rest, to which he says it must return. This is the rest of the great sabbath, in which each of the saints is above the sensible things of the world, devoting himself entirely to deep and invisible mystery and cleaving to God. This is that rest of the sabbath on which God rested from all the works of his world.
Gospel — Mark 1:40-45
John Chrysostom
On 1:40
(Hom. 25. in Matt) Further, the reason why He touches the leper, and did not confer health upon him by word alone, was, that it is said by Moses in the Law, that he who touches a leper, shall be unclean till the evening; that is, that he might shew, that this uncleanness is a natural one, that the Law was not laid down for Him, but on account of mere men. Furthermore, He shews that He Himself is the Lord of the Law; and the reason why He touched the leper, though the touch was not necessary to the working of the cure, was to shew that He gives health, not as a servant, but as the Lord.
On 1:40
(non occ.) For the leper every where proclaimed his wonderful cure, so that all ran to see and to believe on the Healer; thus the Lord could not preach the Gospel, but walked in desert places; wherefore there follows, And they came together to him from all places.
On 1:42
(Hom. 25. in Matt) Moreover, by this, not only did He not take away the opinion of Him entertained by the leper, but He confirmed it; for He puts to flight the disease by a word, and what the leper had said in word, He filled up in deed; wherefore there follows, And when he had spoken, immediately, &c.
On 1:44
(Hom. 25) As if He said, It is not yet time that My works should be preached, I require not thy preaching. By which He teaches us not to seek worldly honour as a reward for our works. It goes on: But go thy way, shew thyself to the chief of the priests. Our Saviour sent him to the priest for the trial of his cure, and that he might not be cast out of the temple, but still be numbered with the people in prayer. He sends him also, that he might fulfil all the parts of the Law, in order to stop the evil-speaking tongue of the Jews. He Himself indeed completed the work, leaving them to try it.
