The Great Commentary of Cornelius a Lapide: S. John
The drawing then of God signifies the force and efficacy of grace. This drawing is sweet and mild, not compelling the free-will, but alluring, soothing, leading it to believe. It also signifies man’s weakness, and vicious desires, which are repugnant to Christian faith and holiness, so that a man needs not so much to be led as dragged by the vehement impulse of God’s grace to Christian faith and virtue. This is what Christ saith (Matt. xi. 12), “ The kingdom of heaven suffereth violence, and the violent seize it.” For the drunkard ought to do violence to his gullet, the unclean to his lust, the avaricious to his avarice, the ambitious man to his ambition. Therefore the drawing of grace lifts to celestial things the will that is drawn down to the flesh. It allures the resisting, and strengthens the weak will. It makes cheerful the sorrowful, and animates the shrinking will to good. Wherefore the Latin Fathers with S. Augustine constantly use these words of Christ against the Pelagians to prove the necessity of grace. I do not say the same of the Greeks, as SS. Chrysostom and Cyril, and those who followed them, who wrote before Pelagius, and therefore speak sparingly concerning grace, that they may make much of man’s free-will against the Manichees. Whence Theophylact from S. Chrysostom says upon this passage, “ As the magnet attracts only iron, so God draws only those who are fit, those who by using their free-will aright render themselves worthy the grace of God.” This is why S. Chrysostom upon this passage must be read with caution, when he says, that those who are drawn by God merit this by some foreseen good wish of free-will. For if you were to understand this of the first drawing of grace, and of simple free-will, it is Pelagianism. But if you understand it of a further drawing to greater faith and virtue, and concerning free-will already influenced and stirred up by previous grace, it is Catholic doctrine.
Observe, (3.) Some are drawn by God inchoately, or so far as God is concerned, and as far as is sufficient, that they may be converted. And yet these do not come to Christ, nor are they converted, because they are unwilling to follow God when He draws them. And without this drawing it is simply impossible to come to Christ, just as impossible as it is for a man to fly without wings. Concerning this drawing, says Maldonatus, if you ask why one man is drawn to Christ, another not, I answer, because the one was willing to follow Christ when He drew, the other was unwilling. Indeed some who were already believers in Christ taking offence at this eating of His Flesh drew back from Him, as John testifies, verse 67. And express mention is made of Judas the traitor, verse 71. Have I not chosen you twelve , and one of you is a devil ? But others are fully drawn by God, they are drawn wholly to Christ. These follow God when He draws them : and of such Christ here also speaks, as appears in the 37th verse. Every thing which the Father giveth Me shall come to Me . Every one that hath heard and learned of the Father cometh unto Me. For to be drawn of the Father means here the same thing as to hear, be taught, to learn of the Father. “What is to be drawn of the Father but to learn of Him ?” says S. Augustine. So those are wholly drawn to whom God gives grace, not only prevenient, effectual, and congruous (for those of whom we have before spoken, who are drawn inchoately, have sufficient grace only), but also co-operating grace. Congruous grace is so called, because it is conformable to the disposition, affections, and character of those who are drawn. Wherefore God foresees that such persons will in fact freely consent and co-operate, and so be converted, believe, and do good works. Concerning those S. Augustine says, “If thou art not drawn, pray that thou mayest be drawn.” And “why one man is drawn, another not, do not scrutinize, if thou wouldst not err.”
Moreover, this effectual and congruous grace is necessary to conversion , faith, and salvation, not simpliciter, but upon the hypothesis of the foreknowledge of God, by which He foresees that this grace will persuade free-will, so that it shall turn itself to God : but that that other grace which is merely sufficient will not persuade it. Wherefore God equally foresees that we will freely consent to effectual and congruous grace, but that to sufficient and incongruous we shall not consent, and this of simple liberty of will. This is what Christ saith, No one can come to Me , except the Father draw him . Wherefore the great gift of perseverance even unto the end of life is congruous grace, and this is the cause of our eternal salvation, and therefore has not to do with merit, but is the peculiar and chief blessing of God, which He confers upon His predestinated and elect, and divides and distinguishes them from the non-elect and reprobate, as S. Augustine teaches at large (de Predest. Sanct. c. 16), and S. Thomas and the Scholastics from him, and the Council of Trent (Sess. 6, c. 13). Wherefore this grace of congruity ought to be constantly and most humbly asked of God, for on it our eternal salvation hinges, and God has promised that He will give us whatsoever we ask in Christ’s name (John xv. 16).
And I will raise , &c. Christ shows in this the fruit of this drawing of God the Father : “ I will indeed give him who, drawn of the Father, shall come to Me, and believe in and obey Me, this reward, that I will raise him up to eternal life and glory, that is to say, if he persevere in faith and obedience until death.”
Ver. 45. — It is written , &c. He quotes Isa. liv. 13, “All thy children shall be taught of the Lord.” Jeremiah (xxxi. 33) has a similar prophecy, and Joel (ii. 28). Because what Christ said seemed strange to the Jews, No one can come to Me, except My Father draw him , Christ confirms it out of Isaiah and the Prophets, who assert that all the children or disciples of Christ would be taught of God. But to be taught by God is to be drawn by God, for this is the force of the Hebrew limmude.
Now, they will be taught by God in that He will at the external voice of Christ and His disciples teach their minds inwardly, illuminate and inspire them, to believe in and obey Him. Whereas previously in the ancient Law, God taught the people exteriorly rather than interiorly, by prophets, priests, and by the Holy Scriptures . Wherefore “where God is the Teacher,” says S. Leo, “there are the lessons quickly learned.” Hear S. Augustine (in Epist. 1 S. Jo. Tract. 3), “ The sound of our words strikes the ear, the Master is within. I have spoken to all, but to whomsoever that unction speaketh not inwardly, whom the Holy Ghost teacheth not within, such depart untaught. The outward instructions and admonitions are some sort of aid; but it is He who sitteth in heaven who teaches the heart. Wherefore He saith Himself in the Gospel, ‘Call no one your master upon earth, for one is your Master, Christ.’ He indeed speaks to you inwardly when no mortal man is by. Where His inspiration, His unction is not, outward words are an empty breath.”
Every one who hath heard . . . and learned , the Arabic adds, and knoweth. See how He explains the drawing of the Father . He is drawn by the Father who is inwardly taught by Him, i.e., whose understanding is illuminated by the Father, and his will inflamed, that he may believe in and follow Me. And he hath learned, or he does learn, that is, he receives My illumination in his intellect, and My impulse in his will : and he acquiesces, and freely consents. This man comes to Me, i.e., he believes in Me as the Messiah, and obeys Me. For the two feet, not of the body, but of the soul, by which she comes to Christ, are the understanding enlightened by God, and the will impelled and inflamed by Him. Hence S. Augustine (de Predest. Sanct. c. 8) says, “ If every one who hath heard and learned of the Father cometh, assuredly every one who cometh not, hath not heard, nor learned of the Father. For if he had heard and learned, he would come.” He subjoins, “This school is far remote from fleshly sense, in which the Father is heard, and teaches us to come to the Son. There, too, is the Son Himself, because He is His Word, by whom He thus teaches us: and this He does not through the ears of the flesh, but of the heart. There also at the same time, is the Spirit of the Father and the Son. And He neither refrains from teaching, nor does He teach differently. For we have learned that the works of the Trinity are inseparable.” And after an interval, “Why therefore does He not teach all to come to Christ, unless because all whom He teaches, He teaches in mercy? But whom He teacheth not, in judgment He teacheth them not. For He hath mercy upon whom He will, and whom He wills He hardeneth. But He is merciful, and doeth good, and when He hardeneth He requiteth justly. This grace therefore which is secretly given to human hearts by the Divine bounty, is rejected by no hard heart. For for this reason is it given that the hardness of the heart may be first taken away. When therefore the Father is heard and teaches inwardly that we should come to the Son, He takes away the heart of stone, and gives a heart of flesh, as He promised by His prophet. For so He makes the sons of promise vessels of mercy which He has prepared for glory.”
