And the Joannine writings compare this higher mental knowledge to the lower, sensible perception: “He who cometh from heaven, witnesseth to what he hath seen and heard,” iii, 31; “when He shall become manifest, we shall see Him as He is,” 1 John iii, 2. And they have three special terms, in common with Gnosticism, for the object of such knowledge: Life, Light, and Fulness (_Plerōma_),--the latter, as a technical term, appearing in the New Testament only in John i, 16, and in the Epistles to the Colossians and Ephesians. Catherine, also, is ever experiencing and conceiving the mental apprehensions of faith, as so many quasi-sensible, ocular, perceptions; and Life and Light are constantly mentioned, and Fulness is, at least, implied in the psycho-physical concomitants or consequences of her thinkings. On the other hand, she does not follow John in the intensely dualistic elements of his teaching,--the sort of determinist, all but innate, distinction between “the darkness,” “the men who loved the darkness rather than the light,” and the Light itself and those who loved it, i, 4, 5; iii, 19,--children of God and children of the devil--the latter all but incapable of being saved, viii, 38-47; x, 26; xi, 52; xiv, 17. Rather is she like him in his all but complete silence as to “the anger of God,”--a term which he uses once only, iii, 36, as against the twenty-two instances of it in St. Paul. And she is full to overflowing of the great central, profoundly un- and anti-Gnostic, sensitively Christian teachings of St. John: as to the Light, the only-begotten Son, having been given by God, because God so loved the world; as to Jesus having loved his own even to the end; as to the object of Christ’s manifestation of His Father’s name to men, being that God’s love for Christ, and indeed Christ Himself, might be within them; and as to how, if they love Him, they will keep His commandments,--His commandment to love each other as He has loved them, iii, 21; iii, 16; xiii, 1; xvii, 26; xiv, 15; xv, 17. In this last great declaration especially do we find the very epitome of Catherine’s life and spirit, of her who can never think of Him as Light and Knowledge only, but ever insists on His being Fire and Love as well; and who has but one commandment, that of Love-impelled, Love-seeking loving. (5) And lastly, in relation to organized, Ecclesiastical Christianity, the Joannine writings dwell, as regards the more general principles, on points which, where positive, are simply presupposed by Catherine; and, where negative, find no echo within her.
