Luke 1:18

Considering his own age, and moreover the barrenness of his wife, Zacharias doubted; as it is said, And Zacharias said to the angel, Whereby shall I know this? as if he said, “How shall this be?” And he adds the reason of his doubting; For I am an old man. An unseasonable time of life, an ill-suited nature; the planter infirm, the soil barren. But it is thought by some a thing unpardonable. in the priest, that he raises a course of objections; for whenever God declares any thing, it becomes us to receive it in faith, and moreover, disputes of this kind are the mark of a rebellious spirit. Hence it follows; And the angel answering said to him, I am Gabriel, who stand before God.

As if he says, “If it were man who promised these miracles, one might with impunity demand a sign, but when an angel promises, it is then not right to doubt. It follows; And I am sent to speak to you.

That when you hear that I am sent from God, you should deem none of the things which are said to you to be of man, for I speak not of myself, but declare the message of Him who sends me. And this is the merit and excellence of a messenger to relate nothing of his own.

Here we must remark, that the angel testifies, that he both stands before God, and is sent to bring good tidings to Zacharias.

For when angels come to us, they so outwardly fulfill their ministry, as at the same time inwardly to be never absent from His sight; since, though the angelic spirit is circumscribed, the highest Spirit, which is God, is not circumscribed. The angels therefore even when sent are before Him, because on whatever mission they go, they pass within Him.

But he gives him the sign which he asks for, that he who spoke in unbelief, might now by silence learn to believe; as it follows; and, behold, you shall be dumb.

That the bonds might be transferred from the powers of generation to the vocal organs. From no regard to the priesthood was he spared, but for this reason was the more smitten, because in a matter of faith he ought to have set an example to others.

Because the word in the Greek may also signify deaf, he well says, Because you believe not, you shall be deaf, and shall not be able to speak. For most reasonably he suffered these two things; as disobedient, he incurs the penalty of deafness; as an objector, of silence.

But the Angel says, And, behold; in other words, “At this instant.” But mark the mercy of God in what follows: Until the day in which these things shall be performed. As if he said, “When by the issues of events I shall have proved my words, and you shall perceive that you are lightly punished, I will remove the punishment from you.” And he points out the cause of the punishment, adding, Because you believe not my words, which shall be fulfilled in their season; not considering His power Who sent me, and before Whom I stand. But if he who was incredulous about a mortal birth is punished how shall he escape vengeance, who speaks falsely of the heavenly and unspeakable birth?

Now while these things were going on within the delay excited surprise among the multitudes who were waiting without, as it follows: And the people waited for Zacharias, an marveled that he tarried. And while various -suspicions were going about, each man repeating them as it pleased him, Zacharias coming forth told by his silence what he secretly endured. Hence it follows, And when he came out, he could not speak.

But Zacharias beckoned to the people, who perhaps inquired the cause of his silence, which, as he was not able to speak, he signified to them by nodding. Hence it follows, And he beckoned to them, and remained speechless.

But a nod is a certain action of the body, without speech endeavoring to declare the will, yet not expressing it.

“He said, I am the voice of one crying in the wilderness: Make straight the way of the Lord, as said Isaiah the prophet.” As He who is peculiarly the Son of God, being no other than the Logos, yet makes use of Logos (reason), for He was the Logos in the beginning, and was with God, the Logos of God, so John, the servant of that Logos, being, if we take the Scripture to mean what it says, no other than a voice, yet uses his voice to point to the Logos. He, then, understanding in this way the prophecy about himself spoken by Isaiah the prophet, says he is a voice, not crying in the wilderness, but “of one crying in the wilderness,” of Him, namely, who stood and cried, “If any man thirst, let him come unto Me and drink.” He it was, too, who said, “Prepare ye the way of the Lord, make His paths straight. …

17. If any one wishes, however, to make up one complete narrative out of all that is said or left unsaid by these two evangelists respectively, on the subject of Christ’s nativity and infancy or boyhood, he may arrange the different statements in the following order: Now the birth of Christ was on this wise. There was, in the days of Herod the king of Judæa, a certain priest named Zacharias, of the course of Abia; and his wife was of the daughters of Aaron, and her name was Elisabeth. And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless. And they had no child, because that Elisabeth was barren, and they both were well stricken in years. …
