Abstract

Researchers agree on ascribing the De incarnatione Christi contra Apollinarium and the De salutari epiphania contra Apollinarium to two different authors, who probably shared the same theological education. The latter not only uses a mature theological style but shows a better knowledge of Apollinarius of Laodicea and his disciples’ writings. Even though the two authors try to demonstrate the presence of a perfect humanity in Christ, against Apollinarian thought, we can find some important differences in their works concerning the topic of the impeccabilitas of Christ and the relationship between sin and freedom. They explain in a different way the theory of salvation according to Apollinarius: while according to the author of De incarnatione Christi contra Apollinarium the man can save himself through the imitation of Christ, for the other writer salvation has been accomplished only because Christ is devoid of any trace of sin.
