Haydock's Catholic Bible Commentary: John
Ver. 11. His own. This regards principally the Jews. Jesus came to them as into his own family, but they did not receive him. It may likewise be extended to the Gentiles, who had groaned so long a time in darkness, and only seemed to wait for the rising sun of justice to run to its light. They likewise did not receive him. These words, though apparently general, must be understood with restriction; as there were some, though comparatively few, of both Jews and Gentiles, who embraced the faith. (Calmet)
Ver. 12. He gave to them power to be made the adoptive sons of God, and heirs of the kingdom of heaven. They are made the children of God by believing and by a new spiritual birth in the sacrament of baptism, not of blood; (literally, not of bloods) not by the will, and desires of the flesh, not by the will of men, nor by human generation, as children are first born of their natural parents, but of God, by faith and divine grace. (Witham)
Ver. 14. And the word was made flesh. This word, or Son of God, who was in the beginning, from all eternity, at the time appointed by the divine decrees, was made flesh, i.e. became man, by a true and physical union of his divine person, (from which the divine nature was inseparable) to our human nature, to a human soul, and a human body, in the womb, and of the substance, of his virgin Mother. From the moment of Christ's incarnation, as all Christians are taught to believe, he that was God from eternity, became also true man. In Jesus Christ, our blessed Redeemer, we believe one divine Person with two natures, and two wills; the one divine, the other human: by which substantial union, one and the same Person became truly both God and man; not two persons, or two sons, as Nestorius, the heretic, pretended. By this union, and a mutual communication of the proprieties of each nature, it is true to say, that the Son of God, remaining unchangeably God, was made man; and therefore that God was truly conceived and born of the virgin Mary, who, on this account, was truly the Mother of God: that God was born, suffered, and died on the cross, to redeem and save us. The word, in this manner made man, dwelt in us, or among us, by this substantial union with our human nature, not morally only, nor after such a manner, as God is said to dwell in a temple; nor as he is in his faithful servants, by a spiritual union, and communication of his divine graces; but by such a real union, that the same person is truly both God and man. --- And we saw his glory, manifested to the world by many signs and miracles; we in particular, who were present at his transfiguration. (Matthew xvii.) --- Full of grace and truth. These words, in the construction, are to be joined in this manner: the word dwelt in us, full of grace and truth; and we have seen his glory, &c. This fulness of grace in Christ Jesus, infinitely surpassed the limited fulness, which the Scripture attributes to St. Stephen, (Acts vi. 8.) or to the blessed virgin Mother: (Luke i. 28.) they are said to be full of grace, only because of an extraordinary communication and greater share of graces than was given to other saints. But Christ, even as man, had a greater abundance of divine graces: and being truly God as well as man, his grace and sanctity were infinite, as was his person. --- As of the only begotten of the Father.[3]
If we consider Christ in himself, and not only as he was made known to men by outward signs and miracles, St. Chrysostom and others take notice that the word as, no ways diminisheth the signification; and that the sense is, we have seen the glory of him, who is truly from all eternity the only begotten Son of the Father: who, as the Scriptures assure us, is his true, his proper Son, his only begotten, who was sent into the world, who descended from heaven, and came from the Father, and leaving the world, returned where he was before, returned to his Father. We shall meet with many such Scripture texts, to shew him to be the eternal Son of his eternal Father; or to shew that the Father was always his Father, and the Son always his Son: as it was the constant doctrine of the Catholic Church, and as such declared in the general council of Nice, that this, his only Son, was born or begotten of the Father before all ages ... God from God, the true God from the true God. It was by denying this truth, "that the Son was the Son always, and the Father always, and from all eternity, the Father;" that the blaspheming Arius began his heresy in his letter to Eusebius of Nicomedia, against his bishop of Alexandria, St. Alexander. See the letter copied by St. Epiphanius, Hær. 69. p. 731. Ed. Petavii. (Witham) --- Dwelt among us. In a material body, like ours, clothed with our nature. He is become mortal, and like us in every thing, but sin and concupiscence. The Greek literally translated, is, he has pitched his tent amongst us, like a stranger and passenger, who makes no long stay in one place. The body in Scripture, is sometimes called a tent or tabernacle, in which the soul dwells, as 2 Peter i. 14. (Calmet)
Ver. 15. Is preferred before me.[4] Literally, is made before me. The sense, says St. Chrysostom is, that he is greater in dignity, deserves greater honour, &c. though born after me, he was from eternity. (Witham)
Ver. 16. And of his fulness we all have received; not only Jews, but also all nations. --- And grace for grace.[5] It may perhaps be translated grace upon grace, as Mr. Blackwall observes, and brings a parallel example in Greek out of Theognis, p. 164. It implies abundance of graces, and greater graces under the new law of Christ than in the time of the law of Moses; which exposition is confirmed by the following verse. (Witham) --- Before the coming of the Messias all men had the light of reason. The Greeks had their philosophy, the Jews the law and prophets. All this was a grace and favour bestowed by God, the author of all good. But since the word was made flesh, God has made a new distribution of graces. He has given the light of faith, and caused the gospel of salvation to be announced to all men; he has invited all nations to the faith and knowledge of the truth. Thus he has given us one grace for another; but the second is infinitely greater, more excellent, and more abundant than the first. The following verse seems to insinuate, that the evangelist means the law by the first grace, and the gospel by the second. Compare likewise Romans i. 17. The Jews were conducted by faith to faith; by faith in God and the law of Moses, to the faith of the gospel, announced by Christ. (Calmet)
Ver. 18. No man hath seen God. No mortal in this life by a perfect union and enjoyment of him. Nor can any creature perfectly comprehend his infinite greatness: none but his only begotten divine Son, who is in the bosom of his Father, not only by an union of grace, but by an union and unity of substance and nature; of which Christ said, (John xiv. 11.) I am in the Father, and the Father in me. (Witham)
Ver. 19. The Jews sent, &c. These men, who were priests and Levites, seem to have been sent and deputed by the sanhedrim, or great council at Jerusalem, to ask of John the Baptist, who was then in great esteem and veneration, whether he was not their Messias; who, as they knew by the predictions of the prophets, was to come about that time. John declared to them he was not. To their next question, if he was not Elias? He answered: he was not: because in person he was not; though our Saviour (Matthew xi. 14.) says he was Elias: to wit, in spirit and office only. Their third question was, if he was a prophet? He answered, no. Yet Christ (Matthew xi.) tells us, he was a prophet, and more than a prophet. In the ordinary acceptation only, they were called prophets who foretold things to come: John then, with truth, as well as humility, could say he was not a prophet; not being sent to foretell the coming of the Messias, but to point him out as already come, and present with the Jews. (Witham)
Ver. 23. The voice of one crying in the wilderness. See Matthew iii. 3.; Mark i. 3.; Luke iii. 4.; and Isaias xl. 3. by all which John was his immediate precursor. (Witham)
Ver. 26. Hath stood. St. John the Baptist, by these words, which he spoke to the priests and Levites, sent to him by the Pharisees, did not mean to tell them, that Jesus was either at the present time standing amongst them, or that he had ever been in the presence of the self same people; but they may be understood two different ways, either with regard to his divinity; and in that sense, Jesus was always by his divine presence amongst them; or in regard to his humanity; either that he lived in the same country, and among their countrymen, or, that he stood actually amongst them, because Jesus was accustomed yearly to go up to Jerusalem on the festival of the Pasch. (Denis the Carthusian)
