Q. 1. Can you summarize what was the heresy of apollinarism?
A. 1. The heresy of "Apollinarism" was proposed by Apollinaris of Laodicea who died in 390 AD.
In 381 AD, the First Council of Constantinople declared Apollinarism as a heresy.
This heresy promoted that Jesus had a human body and lower soul (the seat of the emotions) but a divine mind. Apollinaris further taught that the souls of men were propagated by other souls, as well as their bodies.
