Eunomius, at one time Bishop of Cyzicus, came into prominence about 355 a.d. Like Arius, he taught that the Son was a creature, though the first and most perfect of God’s creatures; His office being to guide other creatures to knowledge of the source of their existence. Religion then in his view consisted in a right and complete intellectual apprehension of a metaphysical principle, and no more. The generation of the Son he regarded as an event in time, not supra-temporal. The point where Eunomius went beyond Arius was the assertion of the comprehensibility for the human mind of the Divine Essence. Those, he said, who declared God to be in His Essence incomprehensible, who taught that He could only know in part and by token, preached an unknown God, and denied all possible knowledge of God, and therefore, since without knowledge of God there could be no Christianity, did not even deserve the name of Christians.
