Introduction
As for what we can say about the things which are exalted, what is fitting is that we begin with the Father, who is the root of the Totality, the one from whom we have received grace to speak about him.

The Father
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.
Not only is he without end - He is immortal for this reason, that he is unbegotten - but he is also invariable in his eternal existence, in his identity, in that by which he is established, and in that by which he is great. Neither will he remove himself from that by which he is, nor will anyone else force him to produce an end which he has not ever desired. He has not had anyone who initiated his own existence. Thus, he is himself unchanged, and no one else can remove him from his existence and his identity, that in which he is, and his greatness, so that he cannot be grasped; nor is it possible for anyone else to change him into a different form, or to reduce him, or alter him or diminish him, - since this is so in the fullest sense of the truth - who is the unalterable, immutable one, with immutability clothing him.
Not only is he the one called "without a beginning" and "without an end," because he is unbegotten and immortal; but just as he has no beginning and no end as he is, he is unattainable in his greatness, inscrutable in his wisdom, incomprehensible in his power, and unfathomable in his sweetness.
