12. Now it came to pass etc. After the condition of the parents has been described, there is described here second the angelic announcement, and first, as regards the circumstances attending the angelic announcement; second, as regards the circumstances attending the announced offspring, at the words: For he shall be great before the Lord etc.
Now three things were attendant upon the promise, namely the execution of the priestly office, the apparition of the heavenly messenger, the announcement of the future conception. Concerning the first, there: It came to pass, while he executed the priesthood etc.; concerning the second, there: And there appeared to him an Angel of the Lord; concerning the third, there: And the Angel said to him.
First therefore is described the execution of the priestly office in the due manner, because according to the congruence of order, the requirement of custom, and the attendance of the devout multitude.
13. (Verse 8). Therefore, indicating the due execution according to the congruence of order, he says: It came to pass, while he executed the priesthood etc.; whence that which is said of Aaron in Ecclesiasticus forty-five applies to him: "The Lord gave him to exercise the priesthood and to have praise, and to glorify the people in his name" etc. And he says: In order, because that ought especially to be done in an orderly manner; First Corinthians fourteen: "Let all things be done honestly and according to order among you." Now order is rightly preserved when the mind of the priest worthily attends the divine presence; and therefore he says: In order, according to what is said of Christ in Hebrews nine, that "he entered into heaven, that he might now appear before the face of God for us."
14. (Verse 9). He also indicates it as due according to the requirement of custom, when he says: According to the custom of the priesthood, his lot was to offer incense. For this custom, that the priest should enter not by usurpation but by lot or election, is right; because it is said in Hebrews five: "Neither does anyone take the honor to himself" etc. Against which it is said of Uzziah in Second Chronicles twenty-six, that wishing to offer incense, he was struck with leprosy; and the sons of Korah were consumed by fire, Numbers sixteen. But this one went forth by lot; whence that of Wisdom three: "For there shall be given to him a chosen gift of faith and a most acceptable lot in the temple of God." He went forth, I say, to offer incense, having entered into the temple of the Lord; Leviticus sixteen: "Taking the censer, drawing incense with his hand, he shall enter beyond the veil into the holy place, so that, the aromatics being placed upon the fire, the vapor may cover the oracle which is over the testimony, and he shall not die."
15. (Verse 10). Thirdly, he indicates it was done in the due manner on account of the attendance of the multitude, when he says: And the whole multitude of the people was outside, praying at the hour of incense. All were obliged to attend and pray together, according to what is said in Acts one: "All were persevering unanimously in prayer." And they stood outside out of reverence, as that publican in Luke eighteen: "The publican, standing afar off, did not dare" etc. And this at the hour of incense, because that was the fitting hour; Second Maccabees one: "All the priests were making prayer while the sacrifice was being consumed"; in which is signified that all our prayer ought to be offered through Christ, who "is heard in all things for his reverence," Hebrews five.
16. (Vers. 11.). And there appeared to him an Angel etc. Here is touched upon secondly the apparition of the heavenly messenger, and this as venerable, as admirable, and as terrible. - Now it is shown to be venerable in its setting: on account of which he says: And there appeared to him an Angel of the Lord, standing at the right side of the altar of incense, which was indeed a place of great reverence: whence, in Leviticus 10, Nadab and Abihu were slain on account of irreverence toward the place; and immediately it is added: "I will be sanctified in those who draw near to me." And he was standing at the right, to signify that he was of the heavenly citizens: Proverbs 3: "Length of days is in her right hand"; and in the Psalm: "The Lord said to my Lord: Sit at my right hand." And therefore he was standing, not sitting, to show that he was a messenger: whence below he says: "I am Gabriel, who stand before God."
17. (Vers. 12.). It is shown to be admirable in appearance: and therefore he says: And Zacharias was troubled upon seeing him, namely from wonder: Esther 15: "I saw you, lord, as an Angel of God, and my heart was troubled from fear of your glory. For you are exceedingly wonderful, lord, and your face is full of graces." For the angelic appearance is wondrous to those in the flesh, because it is unusual: whence the Angel said to Manoah, Judges 13: "Why do you ask my name, which is wonderful?"
18. It is shown to be terrible from the encounter: and therefore he says: And fear fell upon him, in which is signified the vehemence of fear, as in Daniel 10: "But I, Daniel alone, saw the vision. Moreover the men who were with me did not see it, but an exceeding great terror fell upon them, and they fled into hiding. But I, being left alone, saw this great vision, and there remained no strength in me." Furthermore, the Angels appeared terrible because they were not yet reconciled to us; whence they were superior to us and appeared as superiors, and therefore they struck fear: Ambrose: "We are accustomed to be troubled and alienated from our senses when we are overwhelmed by the encounter of a superior power."
19. (Vers. 13.). And the Angel said to him. Here is touched upon thirdly the announcement of the future conception, as strengthening the irascible power, as instructive of the rational power, and as consoling the concupiscible power. - It is shown to be strengthening in that he says: Fear not, Zacharias, for your prayer has been heard. If God hears men, then one must hope in him, and therefore give thanks, not be afraid; Genesis 15: "Fear not, Abram: I am your protector." And that it has been fully heard, the sign is the sending of a messenger: Tobit 3: "At that time the prayers of both were heard. And the Angel Raphael was sent" etc. Similarly the Angel said in Daniel 10: "Do not fear, Daniel, for from the first day that you set your heart to understand, that you might afflict yourself in the sight of your God, your words have been heard."
20. The announcement is described as instructive, whereby he foretells the offspring and predicts the name. And your wife Elizabeth shall bear you a son, and you shall call his name John: she shall bear, I say, to you, because from you and for your consolation, according to what was promised to Abraham in Genesis 15: "He who shall come forth from your body, him you shall have as heir." And he adds the name of the same, according to that passage in Isaiah 49, which is spoken in the person of John himself: "The Lord called me from the womb, from the bowels of my mother he was mindful of my name."
21. (Verse 14). It is described lastly as consoling in the words: And you shall have joy and exultation: Proverbs 23: "The father of the just exults with joy," that is, Zacharias, the father of John; and "he who has begotten a wise son shall rejoice in him," because Proverbs 10: "A wise son makes the father glad." - Nor shall that joy be singular, but common. And therefore he says: Many shall rejoice at his birth: Proverbs 29: "In the multitude of the just the people shall rejoice"; Jeremiah 33: "It shall be to me a name and a joy and a praise and an exultation to all the nations of the earth." Ambrose: "The birth of the saints brings joy to many, because it is a common good. For justice is a common virtue." "Rejoice therefore, you just, in the Lord; praise befits the upright."
22. (Verse 15). For he shall be great before the Lord. Above, the angelic announcement was described with respect to the attendant circumstances on its own part; here it is described with respect to the circumstances on the part of what is promised. For the son to be born is commended in three respects, namely in life, grace and doctrine. And the first regards action, the second regards affection, the third regards intellect; the first, at: He shall be great before the Lord; the second, at: And he shall be filled with the Holy Spirit: the third, at: And many of the children of Israel etc.
23. Therefore the son to be born, whom he declared to be the father's joy, he first commends in life with respect to the existence of virtue and with respect to the evidence of holiness. -- The existence of virtue he touches upon when he says: He shall be great before the Lord, as in Job 1: "That man was great among all the people of the East," not among sinners, who are great in the sight of men, but among the just, so that at his birth that passage below in chapter 7 could be said: "A great prophet has risen among us," etc. Truly a great Prophet, because according to the praise of the Savior in Matthew 11, he is a Prophet, "and more than a Prophet," and so great that the Savior says in the same place: "Among those born of women," etc.
24. The evidence of holiness he touches upon in what he says: And he shall drink neither wine nor strong drink: in which is designated the austerity of life, which is a sign of interior holiness, according to that passage in Galatians 5: "Those who are Christ's have crucified their flesh," etc. By these two things he excludes every drink that can intoxicate. "For it is fitting that a vessel consecrated to heavenly grace abstain from the enticements of the world"; whence it is said to Aaron and his sons in Leviticus 10: "Wine and everything that can intoxicate you shall not drink when you enter the tabernacle of the testimony, lest you die." This was also prohibited to the Nazirites from the time of their consecration, Numbers 6. This was a great thing in blessed John, that with such great innocence there was such great abstinence.
25. Secondly, he is commended in grace with respect to its consummation and acceleration. On account of the consummation he says: He shall be filled with the Holy Spirit, so that of him can be said that passage from Ecclesiasticus 15:
"And he shall fill him with the Spirit of wisdom and understanding," etc. For only the Holy Spirit fills the capacity of the soul, according to that passage in Wisdom 1: "The Spirit of the Lord has filled the whole world." And this is what the Apostle prayed for, in Ephesians 3: "That you may be filled unto all the fullness of God."
26. On account of the acceleration he says: Even from his mother's womb. In testimony of which it is said below in the same chapter: "The infant leaped for joy in my womb." Whence Ambrose says: "Not yet was there in him the spirit of life, and already there was the spirit of grace"; not, I say, was it there according to appearance, yet the vital spirit was there according to existence. A similar thing preceded in Jeremiah 1: "Before I formed you in the womb, I knew you, and before you came forth from the womb, I sanctified you."
27. (Verse 16). Thirdly, he commends him in doctrine with respect to the efficacy of usefulness and with respect to the eminence of authority. On account of the efficacy of usefulness he says: And he shall convert many of the children of Israel to the Lord their God. And this is the greatest usefulness: James, last chapter: "He who causes a sinner to be converted from the error of his way shall save his soul from death and shall cover a multitude of sins." This is what the Lord especially seeks, that they be converted to him; Zechariah 1: "Be converted to me, says the Lord of hosts, and I will be converted to you, says the Lord of hosts." Be converted to me, namely through penance, and I will be converted to you, through pardon: Jeremiah 3: "Be converted, O returning children, and I will heal your backslidings."
28. (Verse 17). On account of the excellence of authority, he adds: And he shall go before him in the spirit and power of Elijah. The spirit and power of Elijah is described in Sirach forty-eight: "Elijah arose like fire, and his word burned like a torch"; and of John it is said in John five: "He was a burning and shining lamp"; and therefore, on account of the great conformity, he is called Elijah: Matthew eleven: "And if you are willing to receive it, he is Elijah"; and also seventeen: "Elijah has already come," etc. And the execution of authority is added in what is said: To turn the hearts of the fathers to the children, that is, the understanding of the Patriarchs to their imitators. Bede: "He turns the hearts of the fathers to the children when he pours into the people by preaching the spiritual understanding of the Saints." This had been foretold concerning Elijah in the last chapter of Malachi: "Behold, I will send you Elijah the prophet, before the great and terrible day of the Lord comes. And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest perhaps I come and strike the earth with anathema." And so that he may be shown in all things conformed to Elijah, he adds: And the unbelieving to the prudence of the just, that is, to faith, which is their prudence, through which they believe themselves to be justified; Romans three: "We reckon that a man is justified by faith without the works of the Law"; whence Habakkuk two: "He who is unbelieving, his soul shall not be right in himself, but the just shall live by his faith." — And because this conversion was preparing for the reception of Christ's coming, therefore he adds: To prepare for the Lord a perfect people. For thus it had been foretold concerning him in Isaiah forty: "The voice of one crying in the desert: Prepare the way of the Lord, make straight in the wilderness the paths of our God." When the path is straight, then it makes one perfect: Proverbs four: "But the path of the just, like a shining light, proceeds and increases even to the perfect day"; John, however, was shining like a lamp and was leading the people by the hand to see the true and perfect light. The authority, therefore, and office of John was to run before and to foretell Christ: whence concerning him is understood that passage in Malachi three: "Behold, I send my Angel, and he shall prepare the way before my face." Whence his preaching was prefigured in the preaching of Moses in Exodus nineteen: "Be prepared for the third day," so that we take day for year, because in the third year after the preaching of John, Christ preached openly. Thus Samuel began in 1 Kings seven: "Prepare your hearts for the Lord," etc.; thus also every preacher: whence Bede: "He who preaches faith and works, what else does he do but prepare the way for the coming Lord to the hearts of his hearers?"
Third, the confirmation of the promise is described in four ways.
29. And Zacharias said etc. The Evangelist described above the conception of the precursor with respect to the condition of the parents and the angelic promise; here he describes with respect to the confirmation of the promise, which he describes in this order. For first is introduced the doubt of the priest; second, the authority of the messenger, at the place: And the Angel answering; third, the sign of authority, at the place: And behold, you shall be silent; fourth, the evidence of the sign, at the place: And the people were waiting.
30. (Verse 18.). He therefore introduces the doubt of the priest, when he says: And Zacharias said to the Angel: How shall I know this? that is, by what sign shall I be made certain? First Corinthians chapter one: "The Jews require signs." — Indeed note that some seek signs for the sake of the publication of the divine promise, as Abraham: Genesis chapter fifteen: "Lord God, how can I know that I shall possess the land?" — Some refuse on account of the obstinacy of their own sin, as Ahaz: Isaiah chapter seven: "Ask for yourself a sign from the Lord your God." — But some seek on account of hesitation of mind, as Zacharias; whence he adds the reason for doubting: For I am an old man, and my wife is advanced in her days; and so there is incapacity on the part of both parents, and so it is no longer the time for begetting, but rather, according to that passage of Ecclesiastes chapter three, "it is a time to be far from embraces"; and therefore he doubted and hesitated. But not so Abraham, of whom it is said in Romans chapter four: "He was not weakened in faith, nor did he consider his own body as dead, when he was nearly a hundred years old, and the dead womb of Sarah. In the promise also of God he did not hesitate through distrust, but was strengthened in faith, giving glory to God, knowing most fully that whatever He promised, God is able also to do." Whence Abraham believed, because he considered the divine power; but Zacharias hesitated, because he considered human incapacity. In this we are instructed that in miracles one must look to the higher causes.
31. (Verse 19.). And the Angel answering etc. Here is noted the authority of the messenger with respect to the contemplative power and with respect to the administrative. With respect to the contemplative he says: I am Gabriel, who stand before God: Daniel 7: "Ten thousand times a hundred thousand stood before him"; and among these was Gabriel. And therefore in 3 Kings 10 the queen of Sheba said in a figure to Solomon: "Blessed are your men, and blessed are these your servants, who stand before you and hear your wisdom." This Micaiah saw, in the last chapter of 3 Kings: "I saw," he said, "the Lord sitting upon his throne, and all the host of heaven standing by him on the right hand and on the left." Therefore dignity is noted in standing before God, and authority in announcing is also noted in this. - With respect to the ministry of mission he says: And I was sent to speak to you and to announce these good tidings to you. Hence he was of the number of those about whom it is said in Hebrews 1: "Are they not all ministering spirits sent forth for ministry" etc.; sent, I say, both to speak and to evangelize. For in speaking the expression of truth is to be understood: Daniel 9: "Behold, the man Gabriel, whom I had seen in the vision at the beginning, flying swiftly, touched me at the time of the evening sacrifice and instructed me and spoke to me." But in evangelization the announcement of goodness is to be understood. For the Gospel is a good announcement: Zechariah 1: "And the Lord answered the Angel who spoke in me good words, consoling words." Hence one ought to say to him that word from 3 Kings 1: "Come in, for you are a mighty man and bring good tidings." For Gabriel is interpreted as the strength of God, and therefore he was sent to strengthen the fearful priest.
32. (Vers. 20.). And behold, you shall be silent etc. Here is touched upon the sign of authority, and he gives a sign of penalty on account of the vice of unbelief. He therefore sets forth the sign of silence up to the appointed time, until the day when these things shall come to pass: so that thus he might say that word of the Psalm: "But I, as a deaf man, heard not; and as a mute man not opening" etc. Nor is it a wonder if he was made mute on account of his own unbelief, since the unbelief of others made Ezekiel mute: Ezekiel 3: "You shall be mute and not as a man who rebukes, because they are a provoking house." — And therefore he adds the reason for the silence, namely the vice of unbelief: Because you did not believe my words, which shall be fulfilled in their time. Conversely, it is said below in the same chapter concerning Mary: "Blessed are you who believed, because those things shall be accomplished that were spoken to you by the Lord." Before the punishment he did not believe, but afterward, because, as is said in Isaiah 28, "affliction alone shall give understanding to the hearing." Therefore the words of God's messengers are not to be despised, because God punishes the unbelieving: Exodus 23: "Behold, I send my Angel"; and it follows: "Observe him and hear his voice, and do not think him one to be despised, for he will not forgive when you have sinned"; Hebrews 2: "For if the word spoken through Angels was made steadfast, and every transgression and disobedience received a just recompense of reward, how shall we escape if we have neglected so great a salvation? Which, having at first begun to be declared by the Lord, was confirmed unto us by those who heard him, God also bearing witness by signs and wonders and various miracles and distributions of the Holy Spirit according to his will." And therefore there is no place for unbelief.
