Luke 3:6

The expression of Scripture, "And all flesh shall see the salvation of God," may without difficulty be understood as if it were said, "And every man shall see the Christ of God." And He certainly was seen in the body, and shall be seen in the body when He judges quick and dead. And that Christ is the salvation of God, many other passages of Scripture witness, but especially the words of the venerable Simeon, who, when he had received into his hands the infant Christ, said, "Now lettest Thou Thy servant depart in peace, according to Thy word: for mine eyes have seen Thy salvation."

(ubi sup.) That is, of the Father, who sent His Son as our Saviour. But the flesh is here taken for the whole man.

(ubi sup.) 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 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. 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 of the law changed into easiness of faith. For it is no longer toils and labors, saith he, but grace, and forgiveness of sins, affording great facility of salvation. Next he states the cause of these things, saying, "All flesh shall see the salvation of God;" no longer Jews and proselytes only, but also all earth and sea, and the whole race of men. Because by "the crooked things" he signified our whole corrupt life, publicans, harlots, robbers, magicians, as many as having been perverted before afterwards walked in the right way: much as He Himself likewise said, "publicans and harlots go into the kingdom of God before you," because they believed. And in other words also again the prophet declared the self-same thing, thus saying, "Then wolves and lambs shall feed together." For like as here by the hills and valleys, he meant that incongruities of character are blended into one and the same evenness of self-restraint, so also there, by the characters of the brute animals indicating the different dispositions of men, he again spoke of their being linked in one and the same harmony of godliness. Here also, as before, stating the cause. That cause is, "There shall be He that riseth to reign over the Gentiles, in Him shall the Gentiles trust:" much the same as here too he said, "All flesh shall see the salvation of God," everywhere declaring that the power and knowledge of these our Gospels would be poured out to the ends of the world, converting the human race, from a brutish disposition and a fierce temper to something very gentle and mild.
