Rise of the Monophysite churches of the Near East
The Coptic descendants of the old Egyptians set up a patriarch of their own at Alexandria. He also became the recognized head of the Abyssinian church. Most of the Armenians withdrew from fellowship with the Orthodox and organized their own hierarchy.
Council of Constantinople
Since Apollinaris’ doctrine marred the perfection of his humanity, it was condemned at the Council of Constantinople in 381. This same Council asserted the divinity of the Holy Spirit. From that time the Athanasian doctrine of the Trinity has held the orthodox position in Christianity.
Donatist controversy
Synods were held at Carthage at which an anti-Roman position was ratified. But the Roman influence was the stronger, and in the end, Augustine fixed the position of the Catholic Church by affirming that once a person was baptized they could be readmitted regardless of their sin by the simple laying on of hands.
