(f) Eusebius of Cæsarea, Creed, in Socrates, Hist. Ec., I, 8. (MSG, 67:69.) Cf. Hahn, § 188.
This creed was presented at the Council of Nicæa by the historian Eusebius, who took the lead of the middle party at the council. He stated that it had long been in use in his church.
We believe in one God, Father Almighty, the maker of all things visible and invisible; and in one Lord Jesus Christ, the Logos of God, God of God, Light of Light, Life of Life, only begotten Son, the first-born of all creation, begotten of His Father before all ages, by whom, also, all things were made, who for our salvation became flesh, who lived among men, and suffered and rose again on the third day, and ascended to the Father, and will come again in glory to judge the living and the dead. We believe also in one Holy Spirit. We believe that each of these [i.e., three] is and subsists;[103] the Father truly Father, the Son truly Son; the Holy Spirit truly Holy Spirit; as our Lord also said, when He sent His disciples to preach: “Go teach all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit” [Matt. 28:19].
(g) Council of Nicæa A. D. 325, Creed, in Socrates, Hist. Ec., I, 8. (MSG, 67:68.) Cf. Hahn, § 142.
The creed of Nicæa is to be carefully distinguished from what is commonly called the Nicene creed. The actual creed put forth at the [pg 306] council is as follows. The discussion by Loofs, Dogmengeschichte, § 32, is brief but especially important, as he shows that the creed was drawn up under the influence of the Western formulæ.
We believe in one God, Father Almighty, maker of all things visible and invisible; and in one Lord Jesus Christ, the Son of God, begotten of His Father, only begotten, that is of the ousia of the Father, God of God, Light of Light, true God of true God; begotten, not made, of one substance[104] with the Father, by whom all things were made, both things in heaven and things in earth, who for us men and for our salvation, came down from heaven and was made [became] flesh and was made [became] man, suffered and rose again on the third day, ascended into the heavens and comes to judge living and dead. And in the Holy Ghost.
But those who say there was when He was not, and before being begotten He was not, and He was made out of things that were not[105] or those who say that the Son of God was from a different substance [hypostasis] or being [ousia] or a creature, or capable of change or alteration, these the Catholic Church anathematizes.
