Luke 3:5

The Word came, and the voice followed. For the Word first works inward, then follows the office of the voice, as it is said, And he went into all the country about Jordan.

Jordan is the same as descending, for there descends from God a river of healing water. But what parts would John be traversing but the country lying about Jordan, that the penitent sinner might soon arrive at the flowing stream, humbling himself to receive the baptism of repentance. For it is added, preaching the baptism of repentance for the remission of sins.

It is plain to every reader that John not only preached the baptism of repentance, but to some also he gave it, yet his own baptism he could not give for the remission of sins.

For as the sacrifice had not yet been offered up, nor had the holy Spirit descended, how could remission of sins be given? What is it then that St. Luke means by the words, for the remission of sins, seeing the Jews were ignorant, and knew not the weight of their sins? Because this was the cause of their evils, in order that they might be convinced of their sins and seek a Redeemer, John came exhorting them to repentance, that being thereby made better and sorrowful for their sins, they might be ready to receive pardon. Rightly then after saying, that he came preaching the baptism of repentance, he adds, for the remission of sins. As if he should say, The reason by which he persuaded them to repent was, as, that thereby they would the more easily obtain despair. For the hill produces no fruit.

Or you may understand the mountains and hills to be the hostile powers, which have been overthrown by the coming of Christ.

But as the hills differ from mountains in respect of height, in other things are the same, so also the adverse powers agree indeed in purpose, but are distinguished from one another in the enormity of their offenses.

Or, the valley when filled increases, but the mountains and hills when brought low decrease, because the Gentiles by faith in Christ receive fullness of grace, but the Jews by their sin of treachery have lost that wherein they boasted. For the humble receive a gift because the hearts of the proud they keep afar off.

Or by these words he declares the difficulties of the law to be turned into the easiness of faith; as if he said, No more toils and labors await us, but grace and remission of sins make an easy way to salvation.

Or, He orders the valleys to be filled, the mountains and hills to be cast down, to show that the rule of virtue neither fails from want of good, nor transgresses from excess.

But the crooked places are become straight, when the hearts of the wicked, perverted by a course of injustice, are directed to the rule of justice. But the rough ways are changed to smooth, when fierce and savage dispositions by the influence of Divine grace return to gentleness and meekness.

He then adds the cause of these things, saying, And all flesh shall see, &c. showing that the virtue and knowledge of the Gospel shall be extended even to the end of the world, turning mankind from savage manners and perverse wills to meekness and gentleness. Not only Jewish converts but all mankind shall see the salvation of God.

That is, of the Father, who sent His Son as our Savior. But the flesh is here taken for the whole man.

Or else, All flesh, i.e. Every man can not see the salvation of God in Christ in this life. The Prophet therefore stretches his eye beyond to the last day of judgment, when all men both the elect and the reprobate shall equally see Him.

But with regard to the countenance of Peter and the rest of the apostles, he tells us that “fourteen years after he went up to Jerusalem,” in order to confer with them about the rule which he followed in his gospel, lest perchance he should all those years have been running, and be running still, in vain, (which would be the case) of course, if his preaching of the gospel fell short of their method. So great had been his desire to be approved and supported by those whom you wish on all occasions to be understood as in alliance with Judaism! When indeed he says, that “neither was Titus circumcised,” he for the first time shows us that circumcision was the only question connected with the maintenance of the law, which had been as yet agitated by those whom he therefore calls “false brethren unawares brought in.” These persons went no further than to insist on a continuance of the law, reta …

7. And the day arrived on which, in very deed, I was to be released from the Professorship of Rhetoric, from which in intention I had been already released. And done it was; and Thou didst deliver my tongue whence Thou hadst already delivered my heart; and full of joy I blessed Thee for it, and retired with all mine to the villa. What I accomplished here in writing, which was now wholly devoted to Thy service, though still, in this pause as it were, panting from the school of pride, my books testify, those in which I disputed with my friends, and those with myself alone before Thee; and what with the absent Nebridius, my letters testify. …

20. But with respect to the mention of Herod, it is well understood that some are apt to be in fluenced by the circumstance that Luke has told us how, in the days of John’s baptizing, and at the time when the Lord, being then a grown man, was also baptized, Herod was tetrarch of Galilee; whereas Matthew tells us that the boy Jesus returned from Egypt after the death of Herod. Now these two accounts cannot both be true, unless we may also suppose that there were two different Herods. But as no one can fail to be aware that this is a perfectly possible case, what must be the blindness in which those persons pursue their mad follies, who are so quick to launch false charges against the truth of the Gospels; and how miserably inconsiderate must they be, not to reflect that two men may have been called by the same name? Yet this is a thing of which examples abound on all sides. …

But Luke expresses somewhat further: not repeating the exordium, and so passing on, but setting down likewise all the prophecy. “For every valley,” saith he, “shall be filled; and every mountain and hill shall be brought low; and the crooked shall be made straight, and the rough ways smooth; and all flesh shall see the salvation of God.” Dost thou perceive how the prophet hath anticipated all by his words; the concourse of the people, the change of things for the better, the easiness of that which was preached, the first cause of all that was occurring, even if he hath expressed it rather as in figure, it being in truth a prophecy which he was uttering? Thus, when he saith, “Every valley shall be filled, and every mountain and hill shall be brought low, and the rough ways shall be made smooth;” he is signifying the exaltation of the lowly, the humiliation of the self-willed, the hardness …
