First Reading — Jonah 3:1-5, 10
Clement of Rome
On 3:4–5
Let us turn to every age that has passed, and learn that, from generation to generation, the Lord has granted a place of repentance to all such as would be converted unto Him... Jonah proclaimed destruction to the Ninevites; but they, repenting of their sins, propitiated God by prayer, and obtained salvation, although they were aliens [to the covenant] of God.
On 3:10
These things, dearly beloved, we are writing, not only to warn you but also to remind ourselves; for we are in the same arena, and the same contest lies before us. For this reason let us abandon empty and silly concerns and come to the glorious and holy rule of our tradition. Let us see what is good and pleasing and acceptable in the sight of our Maker. Let us fix our gaze on the blood of Christ and realize how precious it is to his Father, seeing that it was poured out for our salvation and brought the grace of conversion to the whole world. Let us look back over all the generations and learn that from generation to generation the Lord has given an opportunity of repentance to all who would return to him. Noah preached penance, and those who heeded were saved. Then Jonah announced destruction to the Ninevites and they repented of their sins, besought God in prayer and, estranged though they were from God, obtained salvation.
Responsorial Psalm — Psalm 25:4-5, 6-7, 8-9
Ambrose of Milan
On 24:4
Now the ways of the Lord are, we may say, certain courses taken in a good life, guided by Christ, who says, "I am the way, and the truth and the life." The way, then, is the surpassing power of God, for Christ is our way, and a good way, too, is he, a way that has opened the kingdom of heaven to believers. Moreover, the ways of the Lord are straight, as it is written: "Make your ways known to me, O Lord." Chastity is a way, faith is a way, abstinence is a way. There is, indeed, a way of virtue, and there is a way of wickedness; for it is written, "And see if there is any way of wickedness in me."
Second Reading — 1 Corinthians 7:29-31
Irenaeus
On 7:31
As to their malignantly asserting that if heaven is indeed the throne of God, and earth His footstool, and if it is declared that the heaven and earth shall pass away, then when these pass away the God who sitteth above must also pass away, and therefore He cannot be the God who is over all; in the first place, they are ignorant what the expression means, that heaven is [His] throne and earth [His] footstool. For they do not know what God is, but they imagine that He sits after the fashion of a man, and is contained within bounds, but does not contain. And they are also unacquainted with [the meaning of] the passing away of the heaven and earth; but Paul was not ignorant of it when he declared, "For the figure of this world passeth away." In the next place, David explains their question, for he says that when the fashion of this world passes away, not only shall God remain, but His servants also, expressing himself thus in the 101st Psalm: "In the beginning, Thou; O Lord, hast founded the earth, and the heavens are the works of Thy hands. They shall perish, but Thou shalt endure, and all shall wax old as a garment; and as a vesture Thou shalt change them, and they shall be changed: but Thou art the same, and Thy years shall not fail. The children of Thy servants shall continue, and their seed shall be established for ever;" pointing out plainly what things they are that pass away, and who it is that doth endure for ever God, together with His servants. And in like manner Esaias says: "Lift up your eyes to the heavens, and look upon the earth beneath; for the heaven has been set together as smoke, and the earth shall wax old like a garment, and they who dwell therein shall die in like manner. But my salvation shall be for ever, and my righteousness shall not pass away."
On 7:31
For since there are real men, so must there also be a real establishment (plantationem), that they vanish not away among non-existent things, but progress among those which have an actual existence. For neither is the substance nor the essence of the creation annihilated (for faithful and true is He who has established it), but "the fashion of the world passeth away;" that is, those things among which transgression has occurred, since man has grown old in them. And therefore this [present] fashion has been formed temporary, God foreknowing all things; as I have pointed out in the preceding book, and have also shown, as far as was possible, the cause of the creation of this world of temporal things. But when this [present] fashion [of things] passes away, and man has been renewed, and flourishes in an incorruptible state, so as to preclude the possibility of becoming old, [then] there shall be the new heaven and the new earth, in which the new man shall remain [continually], always holding fresh converse with God. And since (or, that) these things shall ever continue without end, Isaiah declares, "For as the new heavens and the new earth which I do make, continue in my sight, saith the Lord, so shall your seed and your name remain."
Gospel — Mark 1:14-20
Bede the Venerable
On 1:14
(ubi sup.) John being put in prison, fitly does the Lord begin to preach: wherefore there follows, Preaching the Gospel, &c. For when the Law ceases, the Gospel arises in its steps.
On 1:14
(ubi sup.) Let no one, however, suppose that the putting of John in prison took place immediately after the forty days’ temptation and the fast of the Lord; for whosoever reads the Gospel of John will find, that the Lord taught many things before the putting of John in prison, and also did many miracles; for you have in his Gospel, This beginning of miracles did Jesus; (John 2:11) and afterwards, for John was not yet cast into prison. (John 3:24) Now it is said, that when John read the books of Matthew, Mark, and Luke, he approved indeed the text of the history, and affirmed that they had spoken truth, but said that they had composed the history of only one year after John was cast into prison, in which year also he suffered. Passing over then the year of which the transactions had been published by the three others, he related the events of the former period, before John was cast into prison. When therefore Mark had said that Jesus came into Galilee, preaching the Gospel of the kingdom, he subjoins, saying, Since the time is fulfilled, &c.
On 1:14
(ubi sup.) Repent, therefore, and believe; that is, renounce dead works; for of what use is believing without good works? The merit of good works does not, however, bring to faith, but faith begins, that good works may follow.
On 1:18
(in Marc. i. 6) Now fishers and unlettered men are sent to preach, that the faith of believers might be thought to lie in the power of God, not in eloquence or in learning. It goes on to say, and immediately they left their nets, and followed him.
On 1:19
(ubi sup.) It may be asked, how he could call two fishers from each of the boats, (first, Peter and Andrew, then having gone a little further, the two others, sons of Zebedee,) when Luke says that James and John were called to help Peter and Andrew, and that it was to Peter only that Christ said, Fear not, from this time thou shalt catch men; (Luke 5:10) he also says, that at the same time, when they had brought their ships to land, they followed him. We must therefore understand that that transaction which Luke intimates happened first, and afterwards that they, as their custom was, had returned to their fishing. So that what Mark here relates happened afterwards; for in this case they followed the Lord, without drawing their boats ashore, (which they would have done had they meant to return,) and followed Him, as one calling them, and ordering them to follow.
