Let us consider briefly, first, what we learn from this Gospel about the nature of God, and then its teaching upon human salvation.
There are three notable expressions about God the Father in the Gospel and First Epistle of St. John: "God is Love"; "God is Light"; and "God is Spirit." The form of the sentences teaches us that these three qualities belong so intimately to the nature of God that they usher us into His immediate presence. We need not try to get behind them, or to rise above them into some more nebulous region in our search for the Absolute. Love, Light, and Spirit are for us names of God Himself. And observe that St. John does not, in applying these semi-abstract words to God, attenuate in the slightest degree His personality. God is Love, but He also exercises love. "God so loved the world." And He is not only the "white radiance" that "for ever shines"; He can "draw" us to Himself, and "send" His Son to bring us back to Him.
The word "Logos" does not occur in any of the discourses. The identification of Christ with the "Word" or "Reason" of the philosophers is St. John's own. But the statements in the prologue are all confirmed by our Lord's own words as reported by the evangelist. These fall under two heads, those which deal with the relation of Christ to the Father, and those which deal with His relation to the world. The pre-existence of Christ in glory at the right hand of God is proved by several declarations: "What if ye shall see the Son of Man ascending where He was before?" "And now, O Father, glorify Me with Thine own self, with the glory which I had with Thee before the world was." His exaltation above time is shown by the solemn statement, "Before Abraham was, I am." And with regard to the world, we find in St. John the very important doctrine, which has never made its way into popular theology, that the Word is not merely the Instrument in the original creation,—"by (or through) Him all things were made,"—but the central Life, the Being in whom life existed and exists as an indestructible attribute, an underived prerogative,[60] the Mind or Wisdom who upholds and animates the universe without being lost in it. This doctrine, which is implied in other parts of St. John, seems to be stated explicitly in the prologue, though the words have been otherwise interpreted. "That which has come into existence," says St. John, "was in Him life" ([Greek: ho gegonen, en autô zôê ên.]) That is to say, the Word is the timeless Life, of which the temporal world is a manifestation. This doctrine was taught by many of the Greek Fathers, as well as by Scotus Erigena and other speculative mystics. Even if, with the school of Antioch and most of the later commentators, we transfer the words [Greek: ho gegonen] to the preceding sentence, the doctrine that Christ is the life as well as the light of the world can be proved from St. John.[61] The world is the poem of the Word to the glory of the Father: in it, and by means of it, He displays in time all the riches which God has eternally put within Him.
In St. John, as in mystical theology generally, the Incarnation, rather than the Cross, is the central fact of Christianity. "The Word was made flesh, and tabernacled among us," is for him the supreme dogma. And it follows necessarily from the Logos doctrine, that the Incarnation, and all that followed it, is regarded primarily as a revelation of life and light and truth. "That eternal life, which was with the Father, has been manifested unto us," is part of the opening sentence of the first Epistle.[62] "This is the message which we have heard of Him and announce unto you, that God is Light, and in Him is no darkness at all." In coming into the world, Christ "came unto His own." He had, in a sense, only to show to them what was there already: Esaias, long before, had "seen His glory, and spoken of Him." The mysterious estrangement, which had laid the world under the dominion of the Prince of darkness, had obscured but not quenched the light which lighteth every man—the inalienable prerogative of all who derive their being from the Sun of Righteousness. This central Light is Christ, and Christ only. He alone is the Way, the Truth, the Life, the Door, the Living Bread, and the True Vine. He is at once the Revealer and the Revealed, the Guide and the Way, the Enlightener and the Light. No man cometh unto the Father but by Him.
The teaching of this Gospel on the office of the Holy Spirit claims special attention in our present inquiry. The revelation of God in Christ was complete: there can be no question that St. John claims for Christianity the position of the one eternally true revelation. But without the gradual illumination of the Spirit it is partly unintelligible and partly unobserved.[63] The purpose of the Incarnation was to reveal God the Father: "He that hath seen Me hath seen the Father." In these momentous words (it has been said) "the idea of God receives an abiding embodiment, and the Father is brought for ever within the reach of intelligent devotion.[64]" The purpose of the mission of the Comforter is to reveal the Son. He takes the place of the ascended Christ on earth as a living and active principle in the hearts of Christians. His office it is to bring to remembrance the teachings of Christ, and to help mankind gradually to understand them. There were also many things, our Lord said, which could not be said at the time to His disciples, who were unable to bear them. These were left to be communicated to future generations by the Holy Spirit. The doctrine of development had never before received so clear an expression; and few could venture to record it so clearly as St. John, who could not be suspected of contemplating a time when the teachings of the human Christ might be superseded.
Let us now turn to the human side of salvation, and trace the upward path of the Christian life as presented to us in this Gospel. First, then, we have the doctrine of the new birth: "Except a man be born anew (or, from above), he cannot see the kingdom of God." This is further explained as a being born "of water and of the Spirit"—words which are probably meant to remind us of the birth of the world-order out of chaos as described in Genesis, and also to suggest the two ideas of purification and life. (Baptism, as a symbol of purification, was, of course, already familiar to those who first heard the words.) Then we have a doctrine of faith which is deeper than that of the Synoptists. The very expression [Greek: pisteuein eis], "to believe on," common in St. John and rare elsewhere, shows that the word is taking a new meaning. Faith, in St. John, is no longer regarded chiefly as a condition of supernatural favours; or, rather, the mountains which it can remove are no material obstructions. It is an act of the whole personality, a self-dedication to Christ. It must precede knowledge: "If any man willeth to do His will, he shall know of the teaching," is the promise. It is the "credo ut intelligam" of later theology. The objection has been raised that St. John's teaching about faith moves in a vicious circle. His appeal is to the inward witness; and those who cannot hear this inward witness are informed that they must first believe, which is just what they can find no reason for doing. But this criticism misses altogether the drift of St. John's teaching. Faith, for him, is not the acceptance of a proposition upon evidence; still less is it the acceptance of a proposition in the teeth of evidence. It is, in the first instance, the resolution "to stand or fall by the noblest hypothesis"; that is (may we not say?), to follow Christ wherever He may lead us. Faith begins with an experiment, and ends with an experience.[65] "He that believeth in Him hath the witness in himself"; that is the verification which follows the venture. That even the power to make the experiment is given from above; and that the experience is not merely subjective, but an universal law which has had its supreme vindication in history,—these are two facts which we learn afterwards. The converse process, which begins with a critical examination of documents, cannot establish what we really want to know, however strong the evidence may be. In this sense, and in this only, are Tennyson's words true, that "nothing worthy proving can be proven, nor yet disproven."
Faith, thus defined, is hardly distinguishable from that mixture of admiration, hope, and love by which Wordsworth says that we live. Love especially is intimately connected with faith. And as the Christian life is to be considered as, above all things, a state of union with Christ, and of His members with one another, love of the brethren is inseparable from love of God. So intimate is this union, that hatred towards any human being cannot exist in the same heart as love to God. The mystical union is indeed rather a bond between Christ and the Church, and between man and man as members of Christ, than between Christ and individual souls. Our Lord's prayer is "that they all may be one, even as Thou, Father, art in Me, and I in Thee, that they also may be one in us." The personal relation between the soul and Christ is not to be denied; but it can only be enjoyed when the person has "come to himself" as a member of a body. This involves an inward transit from the false isolated self to the larger life of sympathy and love which alone makes us persons. Those who are thus living according to their true nature are rewarded with an intense unshakeable conviction which makes them independent of external evidences. Like the blind man who was healed, they can say, "One thing I know, that whereas I was blind, now I see." The words "we know" are repeated again and again in the first Epistle, with an emphasis which leaves no room for doubt that the evangelist was willing to throw the main weight of his belief on this inner assurance, and to attribute it without hesitation to the promised presence of the Comforter. We must observe, however, that this knowledge or illumination is progressive. This is proved by the passages already quoted about the work of the Holy Spirit. It is also implied by the words, "This is life eternal, that they should know Thee, the only true God, and Jesus Christ whom Thou hast sent." Eternal life is not [Greek: gnôsis], knowledge as a possession, but the state of acquiring knowledge ([Greek: hina gignôskôsin]). It is significant, I think, that St. John, who is so fond of the verb "to know," never uses the substantive [Greek: gnôsis].
The state of progressive unification, in which we receive "grace upon grace," as we learn more and more of the "fulness" of Christ, is called by the evangelist, in the verse just quoted and elsewhere, eternal life. This life is generally spoken of as a present possession rather than a future hope. "He that believeth on the Son hath everlasting life"; "he is passed from death unto life"; "we are in Him that is true, even Jesus Christ. This is the true God, and eternal life." The evangelist is constantly trying to transport us into that timeless region in which one day is as a thousand years, and a thousand years as one day.
St. John's Mysticism is thus patent to all; it is stamped upon his very style, and pervades all his teaching. Commentators who are in sympathy with this mode of thought have, as we might expect, made the most of this element in the Fourth Gospel. Indeed, some of them, I cannot but think, have interpreted it so completely in the terms of their own idealism, that they have disregarded or explained away the very important qualifications which distinguish the Johannine theology from some later mystical systems. Fichte, for example, claims St. John as a supporter of his system of subjective idealism (if that is a correct description of it), and is driven to some curious bits of exegesis in his attempt to justify this claim. And Reuss (to give one example of his method) says that St. John cannot have used "the last day" in the ordinary sense, "because mystical theology has nothing to do with such a notion.[66]" He means, I suppose, that the mystic, who likes to speak of heaven as a state, and of eternal life as a present possession, has no business to talk about future judgment. I cannot help thinking that this is a very grave mistake. There is no doubt that those who believe space and time to be only forms of our thought, must regard the traditional eschatology as symbolical. We are not concerned to maintain that there will be, literally, a great assize, holden at a date and place which could be announced if we knew it. If that is all that Reuss means, perhaps he is right in saying that "mystical theology has nothing to do with such a notion." But if he means that such expressions as those referred to in St. John, about eternal life as something here and now, imply that judgment is now, and therefore not in the future, he is attributing to the evangelist, and to the whole array of religious thinkers who have used similar expressions, a view which is easy enough to understand, but which is destitute of any value, for it entirely fails to satisfy the religious consciousness. The feeling of the contrast between what ought to be and what is, is one of the deepest springs of faith in the unseen. It can only be ignored by shutting our eyes to half the facts of life. It is easy to say with Browning, "God's in His heaven: all's right with the world," or with Emerson, that justice is not deferred, and that everyone gets exactly his deserts in this life; but it would require a robust confidence or a hard heart to maintain these propositions while standing among the ruins of an Armenian village, or by the deathbed of innocence betrayed. There is no doubt a sense in which it may be said that the ideal is the actual; but only when we have risen in thought to a region above the antitheses of past, present, and future, where "is" denotes, not the moment which passes as we speak, but the everlasting Now in the mind of God. This is not a region in which human thought can live; and the symbolical eschatology of religion supplies us with forms in which it is possible to think. The basis of the belief in future judgment is that deep conviction of the rationality of the world-order, or, in religious language, of the wisdom and justice of God, which we cannot and will not surrender. It is authenticated by an instinctive assurance which is strongest in the strongest minds, and which has nothing to do with any desire for spurious "consolations";[67] it is a conviction, not merely a hope, and we have every reason to believe that it is part of the Divine element in our nature. This conviction, like other mystical intuitions, is formless: the forms or symbols under which we represent it are the best that we can get. They are, as Plato says, "a raft" on which we may navigate strange seas of thought far out of our depth. We may use them freely, as if they were literally true, only remembering their symbolical character when they bring us into conflict with natural science, or when they tempt us to regard the world of experience as something undivine or unreal.
It is important to insist on this point, because the extreme difficulty (or rather impossibility) of determining the true relations of becoming and being, of time and eternity, is constantly tempting us to adopt some facile solution which really destroys one of the two terms. The danger which besets us if we follow the line of thought natural to speculative Mysticism, is that we may think we have solved the problem in one of two ways, neither of which is a solution at all. Either we may sublimate our notion of spirit to such an extent that our idealism becomes merely a sentimental way of looking at the actual; or, by paring down the other term in the relation, we may fall into that spurious idealism which reduces this world to a vain shadow having no relation to reality. We shall come across a good deal of "acosmistic" philosophy in our survey of Christian Platonism; and the sentimental rationalist is with us in the nineteenth century; but neither of the two has any right to appeal to St. John. Fond as he is of the present tense, he will not allow us to blot from the page either "unborn to-morrow or dead yesterday." We have seen that he records the use by our Lord of the traditional language about future judgment. What is even more important, he asserts in the strongest possible manner, at the outset both of his Gospel and Epistle, the necessity of remembering that the Christian revelation was conveyed by certain historical events. "The Word was made flesh, and tabernacled among us, and we have seen His glory." "That which was from the beginning, that which we have heard, that which we have seen with our eyes, that which we beheld, and our hands handled, concerning the Word of Life … that which we have seen and heard declare we unto you." And again in striking words he lays it down as the test whereby we may distinguish the spirit of truth from Antichrist or the spirit of error, that the latter "confesseth not that Jesus Christ is come in the flesh." The later history of Mysticism shows that this warning was very much needed. The tendency of the mystic is to regard the Gospel history as only one striking manifestation of an universal law. He believes that every Christian who is in the way of salvation recapitulates "the whole process of Christ" (as William Law calls it)—that he has his miraculous birth, inward death, and resurrection; and so the Gospel history becomes for the Gnostic (as Clement calls the Christian philosopher) little more than a dramatisation of the normal psychological experience.[68] "Christ crucified is teaching for babes," says Origen, with startling audacity; and heretical mystics have often fancied that they can rise above the Son to the Father. The Gospel and Epistle of St. John stand like a rock against this fatal error, and in this feature some German critics have rightly discerned their supreme value to mystical theology.[69] "In all life," says Grau, "there is not an abstract unity, but an unity in plurality, an outward and inward, a bodily and spiritual; and life, like love, unites what science and philosophy separate." This co-operation of the sensible and spiritual, of the material and ideal, of the historical and eternal, is maintained throughout by St. John. "His view is mystical," says Grau, "because all life is mystical." It is true that the historical facts hold, for St. John, a subordinate place as evidences. His main proof is, as I have said, experimental. But a spiritual revelation of God without its physical counterpart, an Incarnation, is for him an impossibility, and a Christianity which has cut itself adrift from the Galilean ministry is in his eyes an imposture. In no other writer, I think, do we find so firm a grasp of the "psychophysical" view of life which we all feel to be the true one, if only we could put it in an intelligible form.[70]
