The death of Jesus Christ demonstrated God's salvation; his resurrection proclaimed him alive. As the Christian community moved from the Old Testament, the word of God, to the Christian Bible, different Christologies were connected. Still, in constantly changing contexts, diverse Christological confessions came up within a wider understanding of the apostolic kerygma. Apollinarius confessed that the incarnate Logos is the subject of all Christological statements, and therefore also of all the antitheses that separate God and creatures. Athanasius' anti-Arian exegesis excludes any Christology that confesses two separate subjects and, confesses a duality of them. When Nestorius, after his appointment as patriarch of Constantinople in 428, triggered the dispute about the Marian title mother of God, he entered the fray with homilies in which he called upon the Antiochene Christology familiar to him. Cyril of Alexandria intervened with the journalistic means available at that time. His attitude was heavily biased against Nestorius.
