(1) He existed before anything other than himself came into being. The Father is a single one, like a number, for he is the first one and the one who is only himself. Yet he is not like a solitary individual. Otherwise, how could he be a father? For whenever there is a "father," the name "son" follows. But the single one, who alone is the Father, is like a root, with tree, branches and fruit. It is said of him that he is a father in the proper sense, since he is inimitable and immutable. Because of this, he is single in the proper sense, and is a god, because no one is a god for him nor is anyone a father to him. For he is unbegotten, and there is no other who begot him, nor another who created him. For whoever is someone's father or his creator, he, too, has a father and creator. It is certainly possible for him to be father and creator of the one who came into being from him and the one whom he created, for he is not a father in the proper sense, nor a god, because he has someone who begot him and who created him. It is, then, only the Father and God in the proper sense that no one else begot. As for the Totalities, he is the one who begot them and created them. He is without beginning and without end.

(55) And now being to speak of the Holy Trinity, we must first say, that there is one God, and he is called the Father and Creator of all Things, who is Almighty, and All in All, whose are all Things, and in whom and from whom all Things proceed, and in whom they remain eternally. And then we say, that he is Three, and has from Eternity generated his Son out of himself, who is his Heart, Light, and Love; and yet they are not two, but one eternal Essence. And further we say, as the holy Scripture tells us, that there is a Holy Spirit, which proceeds from the Father and the Son, and that there is but one Essence in the Father, Son, and Holy Ghost, which is rightly spoken.

(11) Wherefore also the apostle designates as "the express image (karakthra) of the glory of the Father " the Son, who taught the truth respecting God, and expressed the fact that the Almighty is the one and only God and Father, "whom no man knoweth but the Son, and he to whom the Son shall reveal Him." That God is one is intimated by those "who seek the face of the God of Jacob;" whom being the only God, our Saviour and God characterizes as the Good Father. And "the generation of those that seek Him" is the elect race, devoted to inquiry after knowledge. Wherefore also the apostle says, "I shall profit you nothing, unless I speak to you, either by revelation, or by knowledge, or by prophecy, or by doctrine."

(1) Just as the Father exists in the proper sense, the one before whom there was no one else, and the one apart from whom there is no other unbegotten one, so too the Son exists in the proper sense, the one before whom there was no other, and after whom no other son exists. Therefore, he is a firstborn and an only Son, "firstborn" because no one exists before him and "only Son" because no one is after him. Furthermore, he has his fruit, that which is unknowable because of its surpassing greatness. Yet he wanted it to be known, because of the riches of his sweetness. And he revealed the unexplainable power, and he combined with it the great abundance of his generosity.
