Mark 1:14

Hearing that John had been delivered into prison, Jesus withdraws into Galilee, in order to show us as well that we must not throw ourselves into temptations, but avoid them, and when we fall into them, endure them.

(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. (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. (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.

After John had been arrested, Jesus came into Galilee, preaching the Gospel of the kingdom of God, etc. With John having been arrested, it was appropriate that he himself began to preach. With the law ceasing, consequently the Gospel arises. If, however, the Savior preaches …

Or, then the beasts dwell with us in peace, as in the ark clean animals with the unclean, when the flesh lusts not against the spirit. After this, ministering Angels are sent to us, that they may give answers and comforts to hearts that watch. When the shadow ceases, the truth comes on; first, John in prison, the Law in Judæa; then, Jesus in Galilee, Paul among the Gentiles preaching the Gospel of the kingdom. For to an earthly kingdom succeeds poverty, to the poverty of Christians is given an everlasting kingdom; but earthly honour is like the foam of water, or smoke, or sleep. For he must repent, who would keep close to eternal good, that is, to the kingdom of God. For he who would have the kernel, breaks the shell; the sweetness of the apple makes up for the bitterness of its root; the hope of gain makes the dangers of the sea pleasant; the hope of health takes away from the painfulness of medicine. They are able worthily to proclaim the preaching of Christ who have deserved to attain to the reward of forgiveness; and therefore after He has said, Repent, He subjoins, and believe the Gospel. For unless ye have believed, ye shall not understand.

And to show us that in persecutions we ought to retire, and not to await them; but when we fall into them, we must sustain them. Or else, the Lord means that the time of the Law is completed; as if He said, Up to this time the Law was at work; from this time the kingdom of God will work, that is, a conversation according to the Gospel, which is with reason likened to the kingdom of heaven. For when you see a man clothed in flesh living according to the Gospel, do you not say that he has the kingdom of heaven, which is not meat and drink, but righteousness and peace and joy in the Holy Ghost? (Rom. 14:17) The next word is, Repent.
