But why is one who comes to baptism bound to confess? For it seems that they need not resort to the power of the keys, since all sins are removed in baptism. The answer is that one is bound at least in general; and he does this, when he renounces Satan and all his pomps. In this way he acknowledges that he is under the yoke of Satan.
(7) But when he saw many... Having showed that many were baptized by John, he now deals with their instruction. In regard to this he does two things: first, he mentions the ones instructed; secondly, their instruction (v. 7c).
He says, therefore: But when he saw many of the Pharisees and Sadducees coming for baptism . It should be noted that among the Jews were certain sects, among which those two were the most prominent: for the Pharisees were so called as though separated from the common life on account of their observances. In many matters they were correct, yet they erred, for it is said that they taught all things happened of necessity. The others, i.e., the Sadducees, were called just on account of certain special observances of the Law; but they did not accept the prophets and did not believe that souls would be raised after the corruption of the body or that they are spirit. But both were conspicuous by their names, because "Phares" signifies division, which is opposed to charity. And they were completely separated from the others, as though they had a superabundant holy Spirit; for this would be good. The others too, i.e., the Sadducees, laid claim to righteousness. Against these Rom (10:3) says: "Being ignorant of the righteousness that comes from God, and seeking to establish their own, they would not submit to God's righteousness." And although they appeared to be more just, they came to John as to a teacher: "Kings shall see and arise; princes, and they shall prostrate themselves; because of the Lord, who is faithful, the holy one of Israel, who has chosen us" (Is 49:7). They, therefore, are instructed in a suitable way.
Hence, who warned you to flee from the wrath to come? And it should be noted that instruction should vary according to the conditions of the audience. For it is enough to speak briefly to the simple about matters of salvation; but to the learned each point should be explained: "I have not been able to speak to you as to spiritual persons, but as to carnal" (2 Cor 3:1). This John did, for he admonished the crowds briefly about penance and announced the kingdom of heaven. These two he explains in detail to the Pharisees. Hence, first he exhorts to penance; secondly, he announces that the kingdom of heaven is near (v. 11). In regard to the first he does two things: first, he gives an inducement to penance; secondly, he removes things which could keep them from penance (v. 9). In regard to the first he does two things: first, he gives the inducement to penance; secondly, he mentions the way of perfect penance (v. 8). Now there are two things that inspire to penance: first, the recognition of one's own sins: "Announce to my people their sins" (Is 58:1); secondly, the fear of God's judgment (v. 7b).
These two John announced; hence he says, You brood of vipers . And it should be noted that in Sacred Scripture one is called a son of another by imitation: "Your father was an Amorite" (Ez 16:45); "you are from your father the devil, and your will is to do your father's desires" (Jn 8:44). They were similar to vipers; therefore he says, You brood of vipers. And they are similar in three ways, according to Chrysostom. For its nature is that when it bites someone, it returns to the water. If it finds water, it does not die; otherwise, it dies. Hence, John considering the intention with which they came to the water of baptism, said, You brood of vipers . But if they were saturated with poison, how did they come for baptism? Because John promised remission of sins, enabling them to enter the water after putting aside their evil intention. Therefore, he says: "Do penance..., and they were baptized by him" (3:2&6). The second property is that in being born, it kills its parents: "Which of the prophets have you not killed?" (Mt 23:31). The third reason is that it is beautiful outwardly but has poison within. These persons are also beautiful outwardly by reason of their pretended righteousness, but within they are infected with sin: "Woe to you, because you are like whitewashed tombs, which outwardly appear beautiful, but within are full of dead men's bones and all uncleanness" (Mt 23:27). According to this, brood of vipers has an evil connotation.
Ambrose explains it another way and says that prudence is ascribed to serpents: "Be prudent as serpents" (Mt 10:16). Hence, John is commending them on their prudence, because they came to be baptized; so he says, brood of vipers . The first thing, therefore, that motivates to penance is the recognition of one's own sin; the second is fear of God's judgment: "By the fear of the Lord a man avoids evil" (Pr 16:6): "Know that there is a judgment" (Jb 19:29). This is why he says, Who warned you to flee from the wrath to come? And it should be noted that Ambrose and Chrysostom explain this about the past, but Rabanus about the future; hence, he says: "Who will show you?" Ambrose explains it thus: Brood of vipers... As if to say: Who has shown you to withdraw from evil? As if to say: No one but God: "O Lord, show us your mercy, and give us your salvation" (Ps 85:7).
According to Chrysostom thus: Brood of vipers , because they retain the will to sin, who warned [showed] you to flee as you wish? It wasn't Isaiah, who said: "Be washed and made clean, and remove the evil of your thoughts from my eyes" (1:16). Nor David, who said: "Wash me thoroughly from my iniquity, and cleanse me from my sin" (Ps 51:2); and later: "The sacrifice acceptable to God is a broken spirit; a broken and contrite heart, O God, you will not despise" (Ps 51:17. Rabanus applies it to the future, as if he were saying: It is good that you are doing penance, because otherwise, who will show... ? "Where shall I go from your spirit? or where shall I flee from your presence?" (Ps 139:7). Anger said of God is not taken for an emotion of the mind, but for its effect; hence, his anger is vengeance.
(8) After mentioning these two things leading to repentance, the evangelist concludes: Bear fruit that befits repentance . Fruit comes after the flowers in a tree, and if the fruit does not follow the flowers, that tree is nothing. For the flower of repentance appears in contrition, but the fruit is in performance. And it should be noted that the fruit of righteousness is one thing and the fruit of repentance another, for more is required of the repentant than of one who does not sin. But the fruit of repentance is threefold: the first is that one punish in himself what he committed: "After you converted me, I did penance; and after I was instructed, I smote upon my thigh," i.e., afflicted my flesh (Jer 31:19). The second is that he flee sins and the occasions of sin; hence, it is said that to make satisfaction is to remove the causes of sin: "Have you sinned, my son? Do so no more, but pray about your former sins... Flee from sin as from a snake" (Sir 21:1-2). The third is that you be as eager to do good as you were to sin: "I am speaking in human terms because of your natural limitations. For just as you once yielded your members to impurity and to greater and greater iniquity, so now yield your members to righteousness and sanctification" (Rom 6:19).
(9) Then he excludes the obstacle to repentance, when he says, And do not presume to say to yourselves: "We have Abraham as our father." The obstacle to repentance is twofold: presuming on oneself and despair about the divine judgment. First, he removes the first; secondly, the second (v. 10).
In regard to the first he does two things: first he excludes the obstacle; secondly, he assigns the reason (9b).
He says, therefore, Do not presume to say to yourselves, We have Abraham as our father." They were of the stock of Abraham according to the flesh; hence, they could believe that no matter how much they sinned, God would have mercy for the sake of Abraham: "Why does your wrath burn hot against your people, O Lord?... Remember Abraham, Isaac and Israel, your servants" (Ex 32:11,13). Therefore, John rejects this: and do not presume to say... This is his way of telling them not to say this, because it will not help them: "It is not the children of the flesh who are the children of God, but the children of the promise are reckoned as descendants" (Rom 9:8). For they gloried greatly in Abraham, but the Lord says: "If you are the sons of Abraham, do the works of Abraham" (Jn 8:39). Against such Chrysostom says: "What does a glorious lineage profit one whose morals degrade him?" The same applies in spiritual matters.
Then he assigns the reason, for I tell you , since it is a greater thing to imitate a great father than to be born of him, God is able from these stones to raise up children to Abraham . It is written in Joshua (c. 4) that when the people of Israel passed across the Jordan on dry ground, Joshua ordered that in memory of the miracle twelve stones outside the river be placed in it. Now John refers to this event, as he baptizes in that place. But this can be understood in two ways:
first, literally, for this is the first foundation of faith, to believe in the omnipotence of God: "I know that you are powerful and no thought is hid from you" (Jb 42:2). —Or by stones we can understand the gentiles, who are called stones for two reasons: first, because they adore stones; secondly, on account of their hardness. And although stones are hard, yet they retain an impression for a long time: and although a building can be slowly made of them, it is strong and durable. Hence, the Gentiles, although they were hard as far as accepting the faith of Christ was concerned, they nevertheless held it firmly. This is signified in Ezekiel (11:19): "I will take a stony heart out of their flesh and give them a heart of flesh; I will put a new spirit within them."
Secondly, according to Jerome, in these words John seems to lead back to the memory of the prophets: "Look to Abraham your father and to Sarah who bore you. Look to the rock from which you were hewn" (Is 51:2). He calls Abraham a rock on account of his inability to reproduce, and Sarah on account of her sterility. As if to say: "God, who made Abraham virile and Sarah fecund, can from these stones raise up children to Abraham.
(10) Even now the axe is laid to the root of the tree . For they could say: "We do not believe that any anger will come upon us; therefore, he removes this by saying, Even now... First, he presents the judgment; secondly, the meaning of the judgment (v. 10b). He says, therefore, Even now... , for there are two reasons why some are not willing to repent:
one is because they do not believe that there is a judgment: "Do not say, I have a sufficiency" (Sir 5:1); "Flee from the face of the sword, because it is the avenger of iniquity; and know that there is a judgment" (Jb 19:29).
The other is because of the delay: "The Lord is not slow about his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance" (2 Pt 3:9).
But John excludes both: first, the first, when he says, Even now the axe ; secondly, the second, when he says, is laid to the root . As if to say: He will not delay. This is understood in three ways:
Chrysostom says that by axe is understood the rigor of divine judgment, which is sometimes designated by axe, sometimes by arrow and by sword: "If a man does not repent, God will whet his sword; he has bent and strung his bow; he has prepared his deadly weapons" (Ps 7:13).
Jerome: "By axe is understood the preaching of the Gospel, because just as by the Gospel teaching some have been brought to life, so its scorners, to death." "Are not my words like fire, and like a hammer that breaks the rock in pieces?" (Jer 23:29); "This child is set for the fall and rising of many in Israel, and for a sign that is spoken against" (Lk 2:34). Even now the axe is laid to the root of the tree . As if to say: It is evident that he is coming.
According to Gregory, by axe is understood our Redeemer, who consists of human and divine nature as of a handle and sword. His human nature, because it waits patiently, is, as it were, held; the divinity cuts as a sword. The axe is laid to the root, because judgment comes through God and men. He says, to the root , for two reasons: first, because in the root is made a general cutting even of that which is in the branches. Secondly, because what is cut off from the root does not germinate. As if to say: the eradication of evils will be universal.
Then he continues and mentions first the universality, saying, every tree . As if to say: As the gentile, so the Jew: "God shows no partiality" (Rom 2:11). Secondly, the guilt, because it does not bear fruit; for punishment comes also for merely omitting: "I was hungry and you did not give me to eat" (Mt 25:42). Thirdly, he mentions two punishments: first, temporal, it is cut down , namely, from this life: "Lo, these three years I have come seeking fruit on this fig tree, and I find none. Cut it down" (Lk 13:7), and after that: "Why should it use up the ground?" This means that it will be cut down along with earthly prosperity Secondly, he mentions the eternal punishment: and thrown into the fire : "Their worm shall not die" (Is 66:24); "Depart, you accursed, into everlasting fire" (Mt 25:41).
(11) I baptize you with water . Above, John exhorted them to do penance, now he intends to do what he had frequently said, namely, to announce the kingdom of heaven. In regard to this he does two things: first, he mentions preparation for the kingdom; secondly, he foretells the kingdom (11b).
That kingdom is Christ, of whom Luke says: "The kingdom of heaven is within you" (17:21). The preparation, of course, is baptism; hence I, indeed , (and this is a marvel to you) baptize in water only, i.e., because I am only a man. Hence, he could merely wash the body and could not give the Holy Spirit, since the payment for sinning had not yet been paid: "Without the shedding of blood there is not forgiveness of sin" (Heb 9:22). Furthermore, the Holy Spirit had not yet descended, nor had Christ sanctified the water by its contact with his flesh. Why then was he baptizing? For three reasons:
first, to anticipate Christ by baptizing: "You will go before the Lord to prepare his ways" (Lk 1:76);
