Take any of the dogmatic systems that have resulted from the latest Protestant dissolvent analysis--that of Kaftan, the follower of Ritschl, for example--and note the extent to which eschatology is reduced. And his master, Albrecht Ritschl, himself says: "The question regarding the necessity of justification or forgiveness can only be solved by conceiving eternal life as the direct end and aim of that divine operation. But if the idea of eternal life be applied merely to our state in the next life, then its content, too, lies beyond all experience, and cannot form the basis of knowledge of a scientific kind. Hopes and desires, though marked by the strongest subjective certainty, are not any the clearer for that, and contain in themselves no guarantee of the completeness of what one hopes or desires. Clearness and completeness of idea, however, are the conditions of comprehending anything--_i.e._, of understanding the necessary connection between the various elements of a thing, and between the thing and its given presuppositions. The Evangelical article of belief, therefore, that justification by faith establishes or brings with it assurance of eternal life, is of no use theologically, so long as this purposive aspect of justification cannot be verified in such experience as is possible now" (_Rechtfertigung und Versöhnung_, vol. iii., chap. vii., 52). All this is very rational, but ... In the first edition of Melanchthon's _Loci Communes_, that of 1521, the first Lutheran theological work, its author omits all Trinitarian and Christological speculations, the dogmatic basis of eschatology. And Dr. Hermann, professor at Marburg, the author of a book on the Christian's commerce with God (_Der Verkehr des Christen mit Gott_)--a book the first chapter of which treats of the opposition between mysticism and the Christian religion, and which is, according to Harnack, the most perfect Lutheran manual--tells us in another place,[18] referring to this Christological (or Athanasian) speculation, that "the effective knowledge of God and of Christ, in which knowledge faith lives, is something entirely different. Nothing ought to find a place in Christian doctrine that is not capable of helping man to recognize his sins, to obtain the grace of God, and to serve Him in truth. Until that time--that is to say, until Luther--the Church had accepted much as _doctrina sacra_ which cannot absolutely contribute to confer upon man liberty of heart and tranquillity of conscience." For my part, I cannot conceive the liberty of a heart or the tranquillity of a conscience that are not sure of their perdurability after death. "The desire for the soul's salvation," Hermann continues, "must at last have led men to the knowledge and understanding of the effective doctrine of salvation." And in his book on the Christian's commerce with God, this eminent Lutheran doctor is continually discoursing upon trust in God, peace of
