The Great Commentary of Cornelius à Lapide
John 14:7
If ye had known Me, &c. Christ meets an objection. The disciples might have objected, "Thou, 0 Christ, declarest that Thou art the way, but the Father is the goal to which thou goest. But we do not know the Father, wherefore neither do we know the goal to which both Thou and we are going. Cause us therefore to know the Father. Again, if the Father is the goal, Thou the way, how sayest Thou, I am the way, the truth, and the life? That is both the way and the goal?" Christ answers that both are true. "For I," saith He, "have one essence with the Father, one and the same Godhead. Wherefore, if ye had known Me clearly and fully, ye would have known My Father also;" for the Apostles knew indeed and believed that Christ was the Son of God, but they did not as yet believe that He was consubstantial with the Father; but they did know this after they had received the Holy Ghost. Wherefore He adds,
And from henceforth ye shall know Him, and have seen Him. Ye shall know is the reading of the Vulgate, of S. Chrysostom, and S. Hilary. He means, Ye shall know the Father at Pentecost by the illumination of the Holy Ghost; yea, ye have already seen Him in Me, for he who seeth Me seeth My Father also, as Christ subjoins. The Greek, Syriac, and Arabic read γινώσκετε, ye know, in the present tense. "Even now ye know the Father, because ye have seen Him in Me working so many miracles. For although ye have not seen Him as He is in His Essence and Godhead, ye have seen Him veiled in My humanity, as with a cloud, by means of the signs and miracles, which, like thunderings and lightnings, come forth from It." So S. Cyril. Ver. 8. Philip saith unto Him, &c. Philip did not understand Christ's answer; how, namely, he who knows Christ knows also the Father. He urges therefore Christ to show them the Father Himself. "Thou sayest that the Father is in Thee, as it were lies hid in Thee. Open Thyself, and shew Him to us."
And it sufficeth us. 1st. Says S. Chrysostom, we desire nothing else but to be shown the Father.
2d. S. Cyril, It sufficeth us, viz., for blessedness, that we should be delivered from all trouble and sorrow; for since the Father is God He will bless us.
3d. It sufficeth us, for confounding the Jews, who deny that Thou art the Son of God.
4th. And more simply, as though it were said, "instead of all the reasons which Thou, 0 Christ, bringest together, to console us in our sorrow for Thy death, we ask one, that Thou wouldst show us the Father. This one will suffice us instead of all the rest."
Anagogically. Hear S. Augustine, "With that joy which shall fill us with His countenance nothing more will be required." This Philip well understood when he said, Lord, show us the Father, and it sufficeth us. But he did not yet understand that he might say, Lord, show us Thyself, and it sufficeth us. But that he might understand this, he received the answer, Have I been so long time with you? &c.
Herein is that saying of S. Augustine true, "Thou sufficest for God, let God be sufficient for thee." For God is Saddai, i.e., sufficiency, abundance of all good things." Wherefore the Psalmist says, "We shall be satisfied when Thy glory shall appear" (Psa 16:15); and, "They shall be inebriated from the richness of Thy house, and Thou shalt give them drink from the torrent of Thy pleasure" (Psa 35:9); and, "Whom have I in heaven but Thee? and there is none upon earth that I desire besides Thee. My flesh and my heart faileth; but God is the strength of my heart, and my portion for ever" (Ps l73:25-26).
The reason à priori is, because God made man after His own image and likeness, wherefore He gave him an infinite capacity, and infinite desires, such as cannot be satisfied with any finite goods. Therefore it is necessary that God alone, who is infinite Good, should fill and satisfy that capacity. As S. Augustine says (lib. 1, Conf. c. 1), "0 Lord, thou hast made us for Thyself, and our heart is restless until it rests in Thee." And the same saith (in Ps. lxii.), "Lovest thou riches? God Himself will be thy riches. Lovest thou a fountain of good? What is more excellent than wisdom? What more full of light? Whatever here can be loved, He who made all things shall be Thine instead of all things." Ver. 9. Jesus saith to him, Have I been so long time three years and a half conversing with you I have taught you who I am, and yet ye have not known Me? The Greek S. Chrysostom and S. Cyril make thou hast not known Me in the sing., that indeed I am not only man, but the Son of God; not diverse in essence and existence from Him, but consubstantial with God the Father. For therefore having seen Me, you still desire to see the Father, because you think that I have a nature wholly different from the Father. As though Philip said, I have seen Jesus the Son of God: it remains for me to see His Father, as being different from Him, as is the case with men. This was the root of Philip's mistake, which Christ removes by what follows.
Philip, he that seeth Me, seeth, &c. "Since I and the Father are plainly one and the same in the essence of Godhead one, I say, not only in likeness, but one indivisibly, therefore he who sees Me in the Humanity which I have assumed, inasmuch as he sees Me, sees My Father also, for I and My Father are one." Where observe, in Christ the Humanity was seen per se, but the Godhead per accidens. For It was seen not as It is in Itself, but through the Humanity, even as the soul is seen by means of the body in which it moves and operates. Wherefore he who with his bodily eye (with regard to which principally Philip asked, and Christ answered) beheld this Man, namely Jesus, per se, beheld indirectly, and per accidens His Godhead, because this Man was truly God. I am speaking as regards the essence of the Godhead, which is common to the Father and the Son. For as regards Person, it was indeed the Person of the Son which assumed human nature, not the Person of the Father. Wherefore he who directly saw this Man (Christ), directly saw the Person of God the Son lying hid in the manhood, but not the Person of God the Father, except by concomitance, as I shall show in ver. 10. Wherefore he who sees or recognises the Godhead of the Son, recognises also the Godhead of the Father, because They are one and the same. So S. Augustine, Cyril, Chrysostom, Hilary, and other Fathers passim. From this passage they prove against the Arians, 1. That Jesus was really God, so that those who saw that Man likewise saw God. 2. That there was one Person of the Father, another of the Son, which the Sabellians denied. For diversity of Persons is denoted by the words Me and Father. 3. That the Son is Consubstantial with the Father. For unless They were Consubstantial, the Son might be seen without seeing the Father: and vice versa, the Father might be seen without beholding the Son, even as happens with men. "You err therefore, 0 Philip, when having seen Me, you desire to see the Father, as though you were about to see another God, and another Deity, when there is but one and the same. How then sayest thou, Show us the Father, when I have shown Him unto thee in Myself?"
This is the true sense in which Christ answers directly the question and meaning of Philip. But because Christ, taking occasion, as He is wont, from the question to rise and to carry His hearers with Him to a loftier height, this passage may, as to its second intention, be taken to apply to the perfect and proper cognition of the Father and the Son, whether by faith or by sight. As it were, He who seeth Me according to the Divinity, seeth also the Father. Because, although He is distinct from Me, yet am I in Him and He in Me by identity of nature. Wherefore He who sees, i.e., who believes, that I am the Son of God, also sees, i.e. believes, that God is my Father. And he who through the beatific vision intuitively beholds Me, intuitively beholds the Father also. So S. Cyril, Augustine, Chrysostom, Maldonatus, and others. Also Suarez, who shows from this passage that the Blessed who see the Divine Essence see also Three Persons in It.
