Haydock's Catholic Bible Commentary: John
Chapter 8
Ver. 1, &c.[1] The last verse of the foregoing chapter, and the eleven verses that follow in this, are not found in the greater part of our present Greek copies, yet they are in some manuscripts and so are retained in the Protestant translation. We read nothing of them in the commentaries of St. Chrysostom or St. Cyril; but St. Jerome (lib. ii. con. Pelag. tom. 4, part 2, p. 521. Ed. Ben.) says, they were found in many both Latin and Greek copies. St. Ambrose (Ep. 52.) says this passage, of the woman taken in adultery, was always famous in the Church. St. Augustine expounds them, tract. in Joan, &c. (Witham)
Ver. 6. Wrote with his finger, as one that was musing about something else. (Witham)
Ver. 7. We cannot with any propriety reprehend or condemn faults in others, if we ourselves be guilty of the same, or other great faults, St. Cyril, in Joan. --- See annotations on Matthew vii, ver. 1.
Ver. 9. Went out one by one,[2] confounded, and as it is in the ordinary Greek copies, convicted by their own conscience. (Witham)
Ver. 11. Hence we may see how impious is the doctrine of those who say that God is the author of sin. Christ did not say to the woman: I do not condemn thy sin; or, go and live now as thou pleasest, I will free thee from all punishment due to any sin thou shalt commit: but he only said, Go, and from henceforth sin no more: thus preserving his amiable virtue of clemency, and still not encouraging vice. (St. Augustine)
Ver. 14. Although I give testimony (or witness) of myself, my testimony is true. He gives them the reason, ver. 16; because he is not alone, but the Father (who also beareth witness) is also with him. (Witham)
Ver. 15. You judge, and also bear testimony concerning other men, according to the flesh, and according to outward shew and appearances only. I judge no one in this manner. And whatever judgment I pass, or if I give testimony, my testimony is true, as coming also from the Father, with whom I am one in nature, though a distinct person: and two, according to the law, are enough to give evidence. (Witham) --- You judge according to the flesh, &c. Because you do not understand the ways of God, and think you only see in me the person of man; therefore I seem to you to be arrogant, bearing witness of myself. Man indeed, who wishes alone to bear testimony of himself, is arrogant, and not to be believed, because all men are frail and liable to be deceived; but light and truth itself can neither deceive nor be deceived. (St. Augustine)
Ver. 16. I am not alone. Christ does not here say that he is the Father and he is the Son, he only says that he is not alone, but that the Father is with him, plainly distinguishing the two Persons. The Father is truly the Father, and the Son truly the Son, not one elder or greater than the other, but both entirely equal in all perfections. One in substance, co-eternal, and of one perfect equality. (St. Augustine)
Ver. 19. Where is thy Father? They knew well enough by other discourses, that he had called and declared God to be his Father; but they had a mind to make him own it again, that they might accuse him as guilty of blasphemy. --- Neither me do you know, nor my Father: you will not own me to have been always his Son, nor him to have been always my Father, but did you know me to be his Son, always proceeding from him, you would know my Father also, and know him as my Father from all eternity. (Witham) --- As in common conversation we often say, "when you have seen one, you have seen the other;" when two persons or things seem perfectly alike as to outward appearances, so here Christ says, If you did know me, you would know my Father also: not that the Father is the Son, or the Son the Father, but because the Father is like the Son. (St. Augustine) --- Here might the Arians, and all who maintain that Christ is a mere creature, blush; for if he were a creature, how can any one who knows him likewise know God? Therefore is Christ consubstantial with the Father, for he who knows the Son, knows the Father also. (Theophylactus)
Ver. 21. I go my way, and you shall seek me, &c. See the foregoing chapter, ver. 34. (Witham)
Ver. 23. I am not of this world: he speaks of his divine person, as the words evidently shew. (Witham)
Ver. 25. Who art thou? Jesus said to them: The beginning,[3] who also speak to you. This text and the construction of it is obscure, both in the Latin and in the Greek. St. Augustine and some of the Latin Fathers, expound it in this manner: I am the beginning of all things, who now being made man, speak to you. But this does not seem the construction, if we consult the Greek text; (where the beginning is not in the nominative, but in the accusative case) and therefore St. Augustine having considered more attentively the Greek, thinks that something must be understood, as believe me to be the beginning: he looks upon this to be the sense and the construction, as being connected with what was said two verses before; to wit, if you believe not that I am he, the true Messias, you shall die in your sins. "That they might," says St. Augustine (tract. 38, num. 11, p. 560) "know what they were to believe," he made them this answer, as if he had said: believe me to be the beginning, the cause, the author of all things, who am now become man, and speak to you. Other later interpreters are of opinion that the beginning is here a Grecism, and signifies the same as at first, or from the beginning. The sense therefore and construction may be, I am, what I said and told you at first, and from the beginning; that is, I am your Messias, the true Son of God, sent into the world, &c. (Witham) --- The Pharisees, indignant at the liberty with which Jesus spoke to them, demand of him in a rage, Who art thou, to speak to us in this imperious manner, to say that we shall die in our sins? Jesus answered them, that he was the Beginning, Author, Creator, and Ruler of all things. This is the more orthodox and more becoming interpretation. Or, I am, in the first place, what I have already told you; viz. (ver. 12.) I am the light of the world; he that followeth me, walketh not in darkness, but shall have the light of life. Or, it may mean, I am what I have always from the beginning told you. I am the Son of God, the Messias, &c. (Calmet)
Ver. 26. And the things I have heard from him, &c. For Christ, to hear from his Father, to see, &c. is the same as to proceed from him, to be of the same nature and substance. See chap. v, ver. 19. (Witham)
Ver. 27. Now they, &c. Some of the more ignorant among the Jews understood not Christ when he clearly enough signified that he was equal to God, and of one and the same nature; but at other times they that heard him, perceived it very well; and so, in this place, they were for stoning him to death. (Witham)
Ver. 28. When you shall have lifted up, &c. That is, have put me to the death of the cross; (see John iii. 14. and xii. 32.) you, that is, many of you, shall know, and believe in me, as your Messias. (Witham)
