5- Widely Known Heresies Concerning the Nature of Christ: 2: The Heresy of Apollinarius

B) The Heresy of Apollinarius:

Apollinarius preached the Divine Nature of Christ, but did not believe in His complete human nature; he considered that the human nature of Christ was not in need of a soul and thus He was without soul because God the Logos provided the needed life. As this implied that the human nature of Christ was incomplete, the Holy Ecumenical Council of Constantinople held in 381 AD condemned Apollnarius and rejected his idea declaring it a heresy.
