procedure as it lies exposed to us in the pages of Scripture. Here the working-out of the Divine purpose supplies the fundamental principle to which all else, even the progressive stages of revelation itself, is subsidiary; and advances in revelation are ever closely connected with the advancing accomplishment of the redemptive purpose. We may understand also, however, from the same central fact, why it is that the doctrine of the Trinity lies in the New Testament rather in the form of allusions than in express teaching, why it is rather everywhere presupposed, coming only here and there into incidental expression, than formally inculcated. It is because the revelation, having been made in the actual occurrences of redemption, was already the common property of all Christian hearts. In speaking and writing to one another, Christians, therefore, rather spoke out of their common Trinitarian consciousness, and reminded one another of their common fund of belief, than instructed one another in what was already the common property of all. We are to look for, and we shall find, in the New Testament allusions to the Trinity, rather evidence of how the Trinity, believed in by all, was conceived by the authoritative teachers of the church, than formal attempts, on their part, by authoritative declarations, to bring the church into the understanding that God is a Trinity. The fundamental proof that God is a Trinity is supplied thus by the fundamental revelation of the Trinity in fact: that is to say, in the incarnation of God the Son and the outpouring of God the Holy Spirit. In a word, Jesus Christ and the Holy Spirit are the fundamental proof of the doctrine of the Trinity. This is as much as to say that all the evidence of whatever kind, and from whatever source derived, that Jesus Christ is God manifested in the flesh, and that the Holy Spirit is a Divine Person, is just so much evidence for the doctrine of the Trinity; and that when we go to the New Testament for evidence of the Trinity we are to seek it; not merely in the scattered allusions to the Trinity as such, numerous and instructive as they are, but primarily in the whole mass of evidence which the New Testament provides of the Deity of Christ and the Divine personality of the Holy Spirit. When we have said this, we have said in effect that the whole mass of the New Testament is evidence for the Trinity. For the New Testament is saturated with evidence of the Deity of Christ and the Divine personality of the Holy Spirit. Precisely what the New Testament is, is the documentation of the religion of the incarnate Son and of the outpourcd Spirit, that is to say, of the r eligion of the Trinity, and what we mean by the doctrine of the Trinity is nothing but the formulation in exact language of the conception of God presupposed in the religion of the incarnate Son and outpoured Spirit. We may analyze this conception and adduce proof for every constituent element of it from the New Testament declarations. We may show that the New Testament everywhere insists on the unity of the Godhead; that it constantly recognizes the Father as God, the Son as God and the Spirit as God; and that it cursorily presents these three to us as distinct Persons. It is not necessary, however, to enlarge here on facts so obvious. We may content ourselves with simply observing that to the New Testament there is but one only living and true God; but that to it Jesus Christ and the Holy Spirit are each God in the fullest sense of the term; and yet Father, Son and Spirit stand over against each other as I, and Thou, and He. In this composite fact the New Testament gives us the doctrine of the Trinity. For the doctrine of the Trinity is but the statement in well guarded language of this composite fact. Thr oughout the whole course of the many efforts to formulate the doctrine exactly, which have followed one another during the entire history of the church, indeed, the principle which has ever determined the result has always been determination to do justice in conceiving the rel ations of God the Father, God the Son and God the Spirit, on the one hand to the unity of God, and, on the other, to the true Deity
