There are a number of passages in the Gospel and First Epistle of St. John which go to show that the author either was, or at least intended to give the impression that he was, an eye-witness of the Life of Christ. We will leave it an open question for the present which of these two alternatives we are to choose. And we will begin by collecting the passages, and justifying the description that has just been given of them. The passages fall into groups; the first small but important, the others larger but, except in a few cases, more indefinite. On the principles of criticism on which we are going, we shall assume that the Gospel and First Epistle that bear the name of St. John are by the same author, and that, so far as the authorship is concerned, what holds good for the one will hold good also for the other. The proof is not absolutely stringent. Identity of style, and close resemblance of ideas, are compatible with duality of authorship, because one writer may imitate another. But in practice, unless the reasons for laying stress upon it are strong and clear, a refinement like this may be left out of account. Of course there is the distinction which Bacon noted between the minds that are quick to observe resemblances and those that are quick to observe differences. This question of the relation of the Gospel of St. John to the First Epistle is a touchstone by which such minds may be distinguished. I allow that the two works may be assigned to different authors[33]. I allow it in the way in which on most questions, if we attempt a nice enumeration of conditions, there is usually some remote possibility to be allowed for. The quotation from Dr. Drummond on the _De Vita Contemplativa_ that I gave in the last lecture may help us to measure how remote the other possibility is. As a practical person, dealing with these questions on a practical scale, I shall venture to assume that the Gospel and the First Epistle are by the same hand. It is of course open to any one to ignore arguments based on this assumption, if he prefers to do so. i. Passages which make a direct claim. I am treading on very familiar ground, but I must ask you to forgive me if I begin by quoting the opening words of the First Epistle: ‘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 (and the life was manifested, and we have seen, and bear witness, and declare unto you the life, the eternal life, which was with the Father, and was manifested unto us); that which we have seen and heard declare we unto you also, that ye also may have fellowship with us: yea, and our fellowship is with the Father, and with his Son Jesus Christ: and these things we write, that our joy may be fulfilled’ (1 John i. 1-3).
