Letter of Eusebius. (Epistola Eusebii.) 43

3. "We believe in One God, the Father Almighty, the Maker of all things visible and invisible. And in One Lord Jesus Christ, the Word of God, God from God, Light from Light, Life from Life, Son Only-begotten, first-born of every creature, before all the ages, begotten from the Father, by Whom also all things were made; Who for our salvation was made flesh, and lived among men, and suffered, and rose again the third day, and ascended to the Father, and will come again in glory to judge the quick and dead. And we believe also in One Holy Ghost:" "believing each of these to be and to exist, the Father truly Father, and the Son truly Son, and the Holy Ghost truly Holy Ghost, as also our Lord, sending forth His disciples for the preaching, said, "Go teach all nations, baptizing them in the Name of the Father and of the Son, and of the Holy Ghost." Concerning Whom we confidently affirm that so we hold, and so we think, and so we have held aforetime, and we maintain this faith unto the death, anathematizing every godless heresy. That this we have ever thought from our heart and soul, from the time we recollect ourselves, and now think and say in truth, before God Almighty and our Lord Jesus Christ do we witness, being able by proofs to shew and to convince you, that, even in times past, such has been our belief and preaching."
