John 8:12

Having absolved the woman from her Sill, lest some should doubt, seeing that He was really man, His power to forgive sins, He deigns to give further disclosure of His divine nature; Then spoke Jesus again to them, saying, I am. the Light of the world.

Where it is to be observed, He does not say, I am the light of Angels, or of heaven, but the Light of the world, i.e. of mankind who live in darkness, as we read, To give light to them that sit in darkness, and in the shadow of death.

As they had brought Galilee as an objection against Him, and doubted His being one of the Prophets, as if that was all He claimed to be, Me wished to show that He was not one of the Prophets, but the Lord of the whole earth: Then spoke Jesus again to them, saying, I am the Light of the world: not of Galilee, or of Palestine, or of Judea.

The Manichaeans suppose the sun of the natural world to be our Lord Christ; but the Catholic Church reprobates such a notion for our Lord Christ was not made the sun, but the sun was made by Him: inasmuch as all things were made by Him. And for our sake did He come to be under the sun being the light which made the sun: He hid Himself under the cloud of the flesh, not to obscure, but to temper His light. Speaking then through the cloud of the flesh, the Light unfailing, the Light of wisdom says to men, I am the Light of the world.

You may bring these words against Nestorius: for our Lord does not say, In Me is the light of the world, but, I am the Light of the world: He who appeared man, was both the Son of God, and the Light of the world; not, as Nestorius fondly holds, the Son of God dwelling in a mere man.

He withdraws you however from the eyes of the flesh, to those of the heart, in that He adds, He that follows Me shall not walk in darkness, but shall have the light of life. He thinks it not enough to say shall have light, but adds, of life. These words of our Lord agree with those of the Psalm, In Your light shall we see light; for with you is the well of life. For bodily uses, light is one thing, and a well another; and a well ministers to the mouth, light to the eyes. With God the light and the well are the same. He who shines upon you, that you may see Him, the Same flows to you, that you may drink Him. What He promises is put in the future tense; what we ought to do in the present. He that follows Me, He says, shall have; i.e. by faith now, in sight hereafter. The visible sun accompanies you, only if you go westward, whither it go also; and even if you follow it, it will forsake you, at its setting. Your God is every where wholly; He will not fall from you, if you fall not from Him. Darkness is to be feared, not that of the eyes, but that of the mind; and if of the eyes, of the inner not the outer eyes; not those by which white and black, but those by which just and unjust, are discerned.

Walk not in darkness, i.e. spiritually abide not in error. Here He tacitly praises Nicodemus and the officers, and censures those who had plotted against Him; as being in darkness and error, and unable to come to the light.

18. To neglect these things any further, and to persevere in the former error, what is it else than to fall under the Lord’s rebuke, who in the psalm reproveth, and says, “What hast thou to do to declare my statutes, or that thou shouldest take my covenant into thy mouth, seeing thou hatest instruction and castest my words behind thee? When thou sawest a thief, thou consentedst with him, and hast been partaker with adulterers.” For to declare the righteousness and the covenant of the Lord, and not to do the same that the Lord did, what else is it than to cast away His words and to despise the Lord’s instruction, to commit not earthly, but spiritual thefts and adulteries? While any one is stealing from evangelical truth the words and doings of our Lord, he is corrupting and adulterating the divine precepts, as it is written in Jeremiah. …

11. Why do you rush into the darkness of jealousy? why do you enfold yourself in the cloud of malice? why do you quench all the light of peace and charity in the blindness of envy? why do you return to the devil, whom you had renounced? why do you stand like Cain? For that he who is jealous of his brother, and has him in hatred, is bound by the guilt of homicide, the Apostle John declares in his epistle, saying, “Whosoever hateth his brother is a murderer; and ye know that no murderer hath life abiding in him.” And again: “He that saith he is in the light, and hateth his brother, is in darkness even until now, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.” Whosoever hates, says he, his brother, walketh in darkness, and knoweth not whither he goeth. …

In Isaiah: “Be comforted, ye weakened hands; and ye weak knees, be strengthened. Ye who are of a timorous heart, fear not. Our God will recompense judgment, He Himself will come, and will save us. Then shall be opened the eyes of the blind, and the ears of the deaf shall hear. Then the lame man shall leap as a stag, and the tongue of the dumb shall be intelligible; because in the wilderness the water is broken forth, and the stream in the thirsty land.” Also in that place: “Not an elder nor an angel, but the Lord Himself shall deliver them; because He shall love them, and shall spare them, and He Himself shall redeem them.” Also in the same place: “I the Lord God have called Thee in righteousness, that I may hold Thine hand, and I will comfort Thee; and I have given Thee for a covenant of my people, for a light of the nations; to open the eyes of the blind, to bring forth them that are b …

The Saviour is here called simply light. But in the Catholic Epistle of this same John we read that God is light. This, it has been maintained, furnishes a proof that the Son is not in substance different from the Father. Another student, however, looking into the matter more closely and with a sounder judgment, will say that the light which shines in darkness and is not overtaken by it, is not the same as the light in which there is no darkness at all. The light which shines in darkness comes upon this darkness, as it were, and is pursued by it, and, in spite of attempts made upon it, is not overtaken. But the light in which there is no darkness at all neither shines on darkness, nor is at first pursued by it, so as to prove victor and to have it recorded that it was not overtaken by its pursuer. …

1. What is it, Brethren, which we have heard the Lord saying, “He that believeth on Me, believeth not on Me, but on Him that sent Me”? It is good for us to believe on Christ, especially seeing that He hath also Himself expressly said this which ye have now heard, that is, that “He had come a Light into the world, and whosoever believeth on Him shall not walk in darkness, but shall have the light of life.” Good then it is to believe on Christ; and a great evil it is not to believe on Christ. But because Christ the Son is, Whatsoever He is, of the Father, but the Father is not of the Son, but is the Father of the Son; He recommends to us indeed faith in Himself, but refers the honour to His Original.

4. But in order that she may do this, hear what she says, what she supplicates, what she prays for. Pray thou for what thou hearest; pray for it when thou hearest it; let these words be the voice of us all: “O send out Thy Light and Thy Truth. They have led me, and brought me on unto Thy holy hill, and into Thy Tabernacles” ( ver. 3 ). For that very “Light” and “Truth” are indeed two in name; the reality expressed is but One. For what else is the “Light” of God, except the “Truth” of God? Or what else is the “Truth” of God, except the “Light” of God? And the one Person of Christ is both of these. …

6. “O God, Thou shalt turn us again, and make us alive” ( ver. 6 ). Not as if we ourselves of our own accord, without Thy mercy, turn unto Thee, and then Thou shalt make us alive: but so that not only our being made alive is from Thee, but our very conversion, that we may be made alive. “And Thy people shall rejoice in Thee.” To their own evil they shall rejoice in themselves: to their own good they shall rejoice in Thee. For when they wished to have joy of themselves, they found in themselves woe: but now because God is all our joy, he that will rejoice securely, let him rejoice in Him who cannot perish. For why, my brethren, will ye rejoice in silver? Either thy silver perisheth, or thou: and no one knows which first: yet this is certain, that both shall perish; which first, is uncertain. …

Do not hold aloof from the Church; for nothing is stronger than the Church. The Church is thy hope, thy salvation, thy refuge. It is higher than the heaven, it is wider than the earth. It never waxes old, but is always in full vigour. Wherefore as significant of its solidity and stability Holy Scripture calls it a mountain: or of its purity a virgin, or of its magnificence a queen; or of its relationship to God a daughter; and to express its productiveness it calls her barren who has borne seven: in fact it employs countless names to represent its nobleness. …

But when you hear that “In Him was Life,” do not imagine Him a compound Being, since farther on he says of the Father also, “As the Father hath Life in Himself, so hath He given to the Son also to have Life” ( John v. 26 ); now as you would not on account of this expression say that the Father is compounded, so neither can you say so of the Son. Thus in another place he says, that “God is Light” ( 1 John i. 5 ), and elsewhere (it is said), that He “dwelleth in light unapproachable” ( 1 Tim. vi. 16 ); yet these expressions are used not that we may suppose a compounded nature, but that by little and little we may be led up to the highest doctrines. For since one of the multitude could not easily have understood how His life was Life Impersonate, he first used that humbler expression, and afterwards leads them (thus) trained to the higher doctrine. …

“And why, pray, did He not speak on these matters with Nathanael, to whom He testified of the truth, nor extend His discourse to any length?” Because even he came not with such zeal as did Nicodemus. For Nicodemus made this his work, and the season which others used for rest he made a season for hearing; but Nathanael came at the instance of another. Yet not even him did Jesus entirely pass by, for to him He saith, “Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of Man.” ( c. i. 51 .) But to Nicodemus He spake not so, but conversed with him on the Dispensation and on eternal life, addressing each differently and suitably to the condition of his will. …

Chap. viii. ver. 12 . “I am the light of the world.” Not “of Galilee,” not of Palestine, nor of Judæa. What then say the Jews?

[1.] What I have often said, I will now say, that Christ looketh not so much to His own honor as to our salvation; not how He may utter some sublime saying, but how something able to draw us to Him. On which account His sublime and mighty sayings are few, and those also hidden, but the humble and lowly are many, and abound through His discourses. For since by these men were the rather brought over, in these He continueth; and He doth not on the one hand utter these universally, lest the men that should come after should receive damage, nor, on the other hand, doth He entirely withhold those, lest the men of that time should be offended. Since they who have passed from lowmindedness unto perfection, will be able from even a single sublime doctrine to discern the whole, but those who were ever lowminded, unless they had often heard these lowly sayings, would not have come to Him at all. …
