First Reading — Hebrews 1:1-6
Clement of Rome
On 1:3–13
This is the way, dear friends, in which we found our salvation, Jesus Christ, the high priest of our offerings, the protector and helper of our weakness. Through him we fix our gaze on the heights of heaven. In him we see mirrored God's pure and transcendent face. Through him the eyes of our hearts have been opened. Through him our foolish and darkened understanding springs up to the light. Through him the Master has willed that we should taste immortal knowledge. For, since "he reflects the glory of God," "he is as much superior to the angels as the name he has obtained is more excellent than theirs." For thus it is written: "He makes his angels winds, and his servants flames of fire." But of his Son this is what the Master said: "You are my son, today I have begotten you. Ask of me, and I will make the nations your heritage, and the ends of the earth your possession." And again he says to him, "Sit at my right hand till I make your enemies your footstool." Who are meant by "enemies"? Those who are wicked and resist his will.
Responsorial Psalm — Psalm 97:1 and 2b, 6 and 7c, 9
Tertullian
On 96:1
For if the earth has to suffer either joy or injury, it is simply on people's account, that they may suffer the joy or the sorrow through the events that happen to their dwelling place, whereby they will rather have to pay the penalty that, simply on their account, even the earth must suffer. When, therefore, God even threatens the earth, I would prefer saying that he threatens the flesh. So likewise, when he makes a promise to the earth, I would rather understand him as promising the flesh; as in that passage of David: "The Lord is King, let the earth be glad," meaning the flesh of the saints, to which appertains the enjoyment of the kingdom of God.
On 96:3
If, however, those whom God has accepted and the believers shall attain salvation, it is necessary that those whom God has rejected and the unbelieving should incur the opposite issue, even the loss of salvation. Now here is a judgment, and those who hold it out before us belong to the Creator. Whom else than the God of retribution can I understand by the one who shall "beat his servants with stripes," either "few or many," and shall exact from them what he had committed to them? Whom is it suitable for me to obey, but him who remunerates? Your Christ proclaims, "I have come to send fire on the earth." That most lenient being, the Lord who has no hell, not long before had restrained his disciples from demanding fire on the churlish village. Whereas he burned Sodom and Gomorrah with a tempest of fire. Of him the psalmist sang, "A fire shall go out before him and burn up his enemies round about." By Hosea he uttered the threat, "I will send a fire on the cities of Judah"; and by Isaiah, "A fire has been kindled in my anger." He cannot lie. If it is not he who spoke even out of the burning bush, it can be of no importance what fire you insist on being understood.
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.
