This doctrine accurately corresponds with the catholic doctrine of our Lord's Person. The Arian heresy denied the true deity of our Lord. The second great heresy was the Apollinarian, which denied His true and perfect humanity. The orthodox doctrine taught the tripartite nature of man, that is, that there was in man, first, a body, secondly, the animal soul which man possesses in common with the beasts, and which perishes at death, and, lastly, the human spirit which is immortal and by which he maintains communion with God. Now the Apollinarian heresy asserted that Jesus Christ possessed a body and a soul, but denied His possession of a spirit. Its theory was that the Divine nature took the place of a true human spirit in Christ, so that Christ was unlike His brethren in this respect, that when the body died, and the animal soul perished, He had no human spirit by which He might enter into Hades, or dwell in Paradise. The Divine nature was the only portion of the Incarnate Lord which then survived. Against this view the words of St. Peter testified beforehand, teaching, by his adaptation of David's prophecy, that our Lord possessed the fulness of humanity in its threefold division, whereby He was enabled to share the experience and lot of His brethren, not only in this life, but also in the intermediate state of Hades, wherein the spirits of the blessed dead await re-union with their bodies, and expect in hope the second advent of their Lord.[64] [64] See the article on "Apollinaris the Younger" in the _Dict. Christ. Biog._, vol. i., for a concise account of the Apollinarian heresy.
