Emperors Arcadius and Honorius issue a new law exiling Apollinarians from Constantinople and confiscating all their meeting places.
According to this new law:
"We command the teachers of the Apollinarians to withdraw with all haste from the habitations of Our dear City [Constantinople]. If they fail to depart and remain in hiding in order to keep holding secret assemblies, then those places or houses in which they have gathered together shall be confiscated." [CTh 16.5.33]
Followers of the teachings of Apollinaris of Laodicea deny that Jesus had a human mind like other human beings. Jesus may have had a human body and soul, but his mind must have been divine.
Apollinarism is thus a form of monophysitism, the heretical idea that Jesus only had "one nature" (divine) instead of two natures (human and divine). Apollinarism was condemned as a heresy in 381.
