Deuteronomy gained its full articulation in conflict with Canaanite impurity; the Johannine writings take shape during the earlier battles of the long war with Gnosticism--the most terrible foe ever, so far, encountered by the Catholic Church, and conquered by her in open and fair fight. Also these writings lay much stress upon Knowing and the Truth: 'this is life eternal, to know Thee, the only true God and Jesus Christ whom Thou hast sent' (xvii. 3); symbolism and mysticism prevail very largely; and, in so far as they are not absorbed in an Eternal Present, the reception of truth and experience is not limited to Christ's earthly sojourn--'the Father will give you another Helper, the spirit of truth who will abide with you forever' (xiv. 16). Yet here the knowing and the truth are also deeply ethical and social: 'he who doeth the truth cometh to the light' (iii. 21); and Christ has a fold, and other sheep not of this fold--them also He must bring, there will be one fold, one Shepherd; indeed, ministerial gradations exist in this one Church (so in xiii. 5-10; xx. 3-8; xxi. 7-19). And the Mysticism here is but an emotional intuitive apprehension of the great historical figure of Jesus, and of the most specifically religious of all facts--of the already overflowing operative existence, previous to all our action, of God, the Prevenient Love. 'Not we loved God (first), but He (first) loved us,' 'let us love Him, because He first loved us,' 'no man can come to Me, unless the Father draw him'--a drawing which awakens a hunger and thirst for Christ and God (1 John iv. 10, 19; John vi. 44; iv. 14; vi. 35).
