1948 Church History and Modern Revelation

The 1948 Course of Study for the Melchizedek Priesthood Quorums of the Church was the second of four volumes called Church History and Modern Revelation which were all written by Elder Joseph Fielding Smith and "Published by The Council of the Twelve Apostles." Lesson forty-five contains this paragraph::

"We know that when Adam was placed on the earth it was pronounced 'good,' and he, as well as the earth, was not subject to death. There was no 'curse' on the earth. There was no blood in his body, but he had a spiritual body until it was changed by the fall. A spiritual body is one which is not quickened by blood, but by spirit. Before the fall Adam had a physical, tangible body of flesh and bones, but it was not quickened by blood. The partaking of the forbidden fruit caused blood to exist in his body and thus the seeds of mortality were sown and his body then became temporal, or mortal, subject to the vicissitudes of mortal change. The Lord created all things upon this earth physically and immortal, or free from the seeds of death. The fall of Adam brought the change upon the earth and all things upon its face partook of the conditions imposed upon Adam in the fall. (2 Nephi 2:22.)"
