Apollinaris argued
that if Christ were perfect God and perfect man, there would be two
Christs, the Son of God by nature and the Son of God by adoption.
Hence He taught that Christ was partly God and partly man; that He
received from the Virgin His body and the lower, irrational soul which
is the condition of bodily life; while His rational Spirit was
Divine. On this theory the ‘whole man,’ as Hilary
says, was not born of the Virgin. Hilary denies the threefold
division. The soul in every case, Christ’s included, is, he
says, the immediate work of God.
