1 John 1:5

Ver. 5 . “For God,” he says, “is light.”

Whatever, then, our poor ability has attempted to suggest with reference to laying hold of repentance once for all, and perpetually retaining it, does indeed bear upon all who are given up to the Lord, as being all competitors for salvation in earning the favour of God; but is chiefly urgent in the case of those young novices who are only just beginning to bedew their ears with divine discourses, and who, as whelps in yet early infancy, and with eyes not yet perfect, creep about uncertainly, and say indeed that they renounce their former deed, and assume (the profession of) repentance, but neglect to complete it. For the very end of desiring importunes them to desire somewhat of their former deeds ; just as fruits, when they are already beginning to turn into the sourness or bitterness of age, do yet still in some part flatter their own loveliness. …

From the Epistle also of John they forthwith cull (a proof). It is said: “The blood of His Son purifieth us utterly from every sin.” Always then, and in every form, we will sin, if always and from every sin He utterly purifies us; or else, if not always , not again after believing; and if not from sin, not again from fornication. But what is the point whence (John) has started? He had predicated “God” to be “Light,” and that “darkness is not in Him,” and that “we lie if we say that we have communion with Him, and walk in darkness.” “If, however,” he says, “we walk in the light, we shall have communion with Him, and the blood of Jesus Christ our Lord purifieth us utterly from every sin.” Walking, then, in the light, do we sin? and, sinning in the light, shall we be utterly purified? By no means. For he who sins is not in the light, but in darkness. …

1. I know that some will attempt to say that, even according to the declarations of our own Scriptures, God is a body, because in the writings of Moses they find it said, that “our God is a consuming fire;” and in the Gospel according to John, that “God is a Spirit, and they who worship Him must worship Him in spirit and in truth.” Fire and spirit, according to them, are to be regarded as nothing else than a body. Now, I should like to ask these persons what they have to say respecting that passage where it is declared that God is light; as John writes in his Epistle, “God is light, and in Him there is no darkness at all.” Truly He is that light which illuminates the whole understanding of those who are capable of receiving truth, as is said in the thirty-sixth Psalm , “In Thy light we shall see light.” For what other light of God can be named, “in which any one sees light,” save an infl …

Seeing God the Father is invisible and inseparable from the Son, the Son is not generated from Him by “prolation,” as some suppose. For if the Son be a “prolation” of the Father (the term “prolation” being used to signify such a generation as that of animals or men usually is), then, of necessity, both He who “prolated” and He who was “prolated” are corporeal. For we do not say, as the heretics suppose, that some part of the substance of God was converted into the Son, or that the Son was procreated by the Father out of things non-existent, i.e., beyond His own substance, so that there once was a time when He did not exist; but, putting away all corporeal conceptions, we say that the Word and Wisdom was begotten out of the invisible and incorporeal without any corporeal feeling, as if it were an act of the will proceeding from the understanding. …

Jesus taught us who it was that sent Him, in the words, “None knoweth the Father but the Son;” and in these, “No man hath seen God at any time; the only-begotten Son, who is in the bosom of the Father, He hath declared Him.” He, treating of Deity, stated to His true disciples the doctrine regarding God; and we, discovering traces of such teaching in the Scripture narratives, take occasion from such to aid our theological conceptions, hearing it declared in one passage, that “God is light, and in Him there is no darkness at all;” and in another, “God is a Spirit, and they that worship Him must worship Him in spirit and in truth.” But the purposes for which the Father sent Him are innumerable; and these any one may ascertain who chooses, partly from the prophets who prophesied of Him, and partly from the narratives of the evangelists. …

“And the light shineth in darkness and the darkness hath not overtaken it.” We are still enquiring about the light of men, since it is what was spoken of in the preceding verse, and also, I consider, about darkness, which is named as its adversary, the darkness also being, if the definition of it is correct, that of men. The light of men is a generic notion covering two special things; and with the darkness of men it is the same. He who has gained the light of men and shares its beams will do the work of light and know in the higher sense, being illuminated by the light of the higher knowledge. And we must recognize the analogous case of those on the other side, and of their evil actions, and of that which is thought to be but is not really knowledge, since those who exercise it have the reason (Logos) not of light but of darkness. …

2. Your late husband, by whose decease you are now a widow, was truly well known to you, but better known to himself than to you. And how could this be, when you saw his face, which he himself did not see, if it were not that the inner knowledge which we have of ourselves is more certain, since no man “knoweth the things of a man, save the spirit of man which is in man”? but when the Lord cometh, “who both will bring to light the hidden things of darkness and will make manifest the counsels of the hearts,” then shall nothing in any one be concealed from his neighbour; nor shall there be anything which any one might reveal to his friends, but keep hidden from strangers, for no stranger shall be there. …

4. Why, then, is scarcely anything ever said in the Scriptures of wisdom, unless to show that it is begotten or created of God? begotten in the case of that Wisdom by which all things are made; but created or made, as in men, when they are converted to that Wisdom which is not created and made but begotten, and are so enlightened; for in these men themselves there comes to be something which may be called their wisdom: even as the Scriptures foretell or narrate, that “the Word was made flesh, and dwelt among us;” for in this way Christ was made wisdom, because He was made man. …

3. But in respect to bodies, it may be the case that this gold and that gold may be equally true [real], but this may be greater than that, since magnitude is not the same thing in this case as truth; and it is one thing for it to be gold, another to be great. So also in the nature of the soul; a soul is not called great in the same respect in which it is called true. For he, too, has a true [real] soul who has not a great soul; since the essence of body and soul is not the essence of the truth [reality] itself; as is the Trinity, one God, alone, great, true, truthful, the truth. …

12. Let no one say, I do not know what I love. Let him love his brother, and he will love the same love. For he knows the love with which he loves, more than the brother whom he loves. So now he can know God more than he knows his brother: clearly known more, because more present; known more, because more within him; known more, because more certain. Embrace the love of God, and by love embrace God. That is love itself, which associates together all good angels and all the servants of God by the bond of sanctity, and joins together us and them mutually with ourselves, and joins us subordinately to Himself. …

8. How shall I make those whose minds are full of vanity understand that the actions of the prophets were also mystical and prophetic? The vanity of their minds is shown in their thinking that we believe God to have once existed in darkness, because it is written, "Darkness was over the deep." As if we called the deep God, where there was darkness, because the light did not exist there before God made it by His word. From their not distinguishing between the light which is God, and the light which God made, they imagine that God must have been in darkness before He made light, because darkness was over the deep before God said, "Let there be light, and there was light." In the New Testament both these things are ascribed to God. …
