Thus, so far as the idea of "knowledge" is concerned, Reitzenstein has not been successful in showing any dependence of Paul upon the mystery religions. But how is it with regard to the doctrine of the "Spirit"? In 1 Cor. ii. 14, 15, the "spiritual man" is contrasted with the "psychic man." The spiritual man is the man who has the Spirit of God; the psychic man is the man who has only a human soul. It is not really correct to say that the spiritual man, according to Paul, is a man not who has the Spirit but who is the Spirit. Paul avoids such an expression for the same reason that prevents his speaking of the "deification" of the Christian. Everywhere in Paul the personal distinction between the believer and the Christ who dwells in him is carefully preserved. His "mysticism" (if the word may be used thus loosely) is never pantheistic. Here already is to be found a most vital difference between Paul and Hermes Trismegistus. But this observation constitutes a digression. It is necessary to return to 1 Cor. ii. 14, 15. The spiritual man, according to that passage, is the man who has the Spirit of God; the psychic man is the man who has only a human soul. Reitzenstein apparently insists that the "only" in this sentence should be left out. The psychic man, according to Paul, he says, has a soul; the spiritual man has no "soul" but has the divine Spirit instead. But such a representation is not really Pauline.[195] Paul clearly teaches that the human soul continues to exist even after the divine Spirit has entered in. "The Spirit himself," he says, "beareth witness with our spirit, that we are children of God" (Rom. viii. 16). Here "our spirit" clearly means "our soul," and is expressly distinguished from the divine Spirit. At every point, then, the attempt to find a pantheistic mysticism in Paul breaks down before the intensely personal character of his religion. The relation of Paul to the risen Christ, intimate as it is, mediated as it is by the all-pervasive Spirit, is a relation of one person to another. [195] See especially Vos, "The Eschatological Aspect of the Pauline Conception of the Spirit," in _Biblical and Theological Studies by the Members of the Faculty of Princeton Theological Seminary_, 1912, pp. 248-250. But it is still necessary to return to the Pauline contrast between the "spiritual man" and the "psychic man." Reitzenstein lays great stress upon that contrast. He regards it as lying at the heart of Paul's religion, and he thinks that he can explain it from the Hellenistic mystery religions. Apparently the method of Reitzenstein can be tested at this point if it can be tested at all. If it does not succeed in explaining the Pauline doctrine of the Spirit, upon which the chief stress is laid, probably it will explain nothing at all.
