John Chrysostom
Catena Aurea · Lukasevangelium 1
And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years. And the angel answering said unto him, I am Gabriel, that stand in the presence of God; and am sent to speak unto thee, and to shew thee these glad tidings. And, behold, thou shalt be dumb, and not able to speak, until the day that these things shall be performed, because thou believest not my words, which shall be fulfilled in their season. And the people waited for Zacharias, and marvelled that he tarried so long in the temple. And when he came out, he could not speak unto them: and they perceived that he had seen a vision in the temple: for he beckoned unto them and remained speechless.
(sup.) 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 thou shalt perceive that thou art rightly punished, I will remove the punishment from thee.” And he points out the cause of the punishment, adding, Because thou believest 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?
