Catherine’s still more pessimistic figure of the body as a prison-house and furnace of purification for the soul, is no doubt the resultant of suggestions received, probably in part through intermediary literature, from the following three passages:--(1) Plato, in his _Cratylus_ (400 B.C.), makes Socrates say: “Some declare that the body (_sōma_) is the grave (_sēma_) of the soul, as she finds herself at present. The Orphite poets seem to have invented the appellation: they held that the soul is thus paying the penalty of sin, and that the body is an enclosure which may be likened to a prison, in which the soul is enclosed until the penalty is paid.” (2) St. Matt. v, 25, 26, gives Our Lord’s words: “Be thou reconciled with thine adversary whilst he is still with thee on the way … lest the Judge hand thee over to the prison-warder, and thou be cast into prison.… Thou shalt not go forth thence, until thou hast paid the uttermost farthing.” And (3) St. Paul declares, 1 Cor. iii, 15: “Every man’s work shall be tested by fire. If a man’s work be burnt, he shall suffer loss; yet he himself shall be saved, yet so as by fire.” These three passages combined will readily suggest, to a soul thirsting for purification and possessed of an extremely sensitive psycho-physical organization with its attendant liability to fever heats, the picture of the body as a flame-full prison-house,--a purgatory of the soul. 2. _St. Paul’s conception of “Spirit.”_ A very difficult complication and varying element is introduced into St. Paul’s Anthropology by the term into which he has poured all that is most original, deepest, most deliberate and abiding in his teaching,--the Spirit, “Pneuma.” For somewhat as he uses the term “Sarx,” the flesh, both in its loose popular signification of “mankind in general”; and in a precise, technical sense of “the matter which composes the earthly body”; so also he has, occasionally, a loose popular use of the term “spirit,” when it figures as but a fourth parallel to “mind,” “heart,” and “conscience”; and, usually, a very strict and technical use of it, when it designates the Spirit, God Himself.
