Vos: "soteric tissue derives its pattern from the eschatological"
“What gives dogmatic coloring to his teaching is largely derived from its antithetical structure, as exhibited in the comprehensive antitheses of the First Adam and the Last Adam, sin and righteousness, the flesh and the Spirit, law and faith, and these are precisely the historic reflections of the one great transcendental antithesis between this world and the world-to-come. It is no wonder that such energetic eschatological thinking tended towards consolidation in and orb of compact theological structure. For in it the world-process is viewed as a unit. The end is placed in the light of the beginning, and all intermediate developments are construed with reference to the purpose a quo (from which, or ultimate purpose; crb) and the terminus ad quem (final finishing point). Eschatology, in other words, even that of the most primitive kind, yields ipso facto (by that very fact) a philosophy of history, be it of the most rudimentary sort. And every philosophy of history bears in itself the seed of a theology.
“...the Pauline outline of history possessed in the Messianic concept a centralizing factor of extraordinary potency, an element whereby the antitheses above named were dissolved into an exceptionally harmonious synthesis...all eschatological interpretation of history, when united to a strong religious mentality cannot but produce the finest practical theological fruitage. To take God as source and end of all that exists and happens, and to hold such a view suffused with the warmth of genuine devotion, stands not only related to theology as the fruit stands to the tree: it is by reason of its essence a veritable theological tree of life.” -- Geerhardus Vos, “The Pauline Eschatology”, pp. 60-61
