'For the weapons of our
warfare are not carnal, but mighty through God to the pulling down
of strong holds;
Casting down reasonings and
every high thing that exalts itself against the knowledge of God,
and bringing into captivity
every thought to the obedience of Christ'
2
Cor.10.4-5
Athanasius on Apollinaris, his former friend and his disciples, whom he does not name. Apollinarism sees the mind of Christ as only Divine, with no place for a human soul, it is heretical. This docetic teaching is contemporary. Further notes and details in this edition.
The main opponent of early docetism was Ignatius of Antioch.
