Paul, the most profound thinker of all the founders of Christianity, very forcibly and clearly expresses this duality when he makes the distinction between “the celestial body” and the “terrestrial.” In mortal life these are united, and death is simply their separation. His disciples have grossly misunderstood and mistaught his explanation. The terrestrial body cannot inherit eternal life, which is the birthright of the celestial. Death is the severance of the cord which unites these bodies in the seemingly indivisible web of earth-life. The terrestrial returns to the elements from which it came; the celestial remains individualized. It is unusual for writers on science at the present day to quote the Bible in support of their theories; but no author before Paul’s time or since has given a more complete philosophy of life, and a key wherewith to unlock the secrets of the grave. DEFINITIONS.--The comparison of terms has led to the strangest processes of reasoning, and the classifications in which some writers delight, have served as a means of intellectual gymnastics, rather than data for clear reasoning. In the threefold division of body, soul and spirit, by using the two last terms, at times as meaning something essentially distinct, and at others, as synonymous with intelligence, and each other; and again making soul and body the same, a most admirable means for the jugglery of disputation is furnished, which has not been left unused, and by which the discussion of this subject has been befogged. There is the physical body, and the spirit to which the manifestations of mind belong. The term soul has no meaning, except as synonymous with body or spirit, and hence is discarded in this discussion.
