Emperor Constantine and the Theology of Christianity from his Autocracy to the Second Ecumenical Council

Abstract

Since his autocracy to his death, Constantine the Great helped the Christianity to be the main religion to all over the empire. This period of time many heresies appeared. They put the unity of Christianity and its teaching in a great danger. Educated people as Arius, Apollinarius, Marcellus, Eunomius and Macedonius tried to explain the nature of God, His actions and His names according to human relationships, their thoughts and their beliefs. The result was a catastrophe, because new heresies were introduced to the Empire. Orthodox Fathers, as Athanasius the Great and Cappadocians Fathers tried to disprove the heresies with success. Upon to these fathers teaching, the First and the Second Ecumenical Councils managed to base their doctrines and to preserve the true teaching and doctrines of Christianity.
