It seems evident, from what I have written above, that in the Hymn to Philippians there is an effort of imitation of a general belief that had secret the name of the Supreme God. A way to say that the supreme god was an Unknown God. An Alien God.
It is curious what the
Gospel of Truth says about the Name:
And the name of the Father is the Son. It is he who, in the beginning, gave a name to him who came forth from him - he is the same one - and he begat him for a son. He gave him his name which belonged to him - he, the Father, who possesses everything which exists around him. He possess the name; he has the son. It is possible for them to see him. The name, however, is invisible, for it alone is the mystery of the invisible about to come to ears completely filled with it through the Father`s agency. Moreover, as for the Father, his name is not pronounced, but it is revealed through a son. Thus, then, the name is great.
Who, then, has been able to pronounce a name for him, this great name, except him alone to whom the name belongs and the sons of the name in whom the name of the Father is at rest, and who themselves in turn are at rest in his name, since the Father has no beginning? It is he alone who engendered it for himself as a name in the beginning before he had created the Aeons, that the name of the Father should be over their heads as a lord - that is, the real name, which is secure by his authority and by his perfect power. For the name is not drawn from lexicons nor is his name derived from common name-giving, But it is invisible. He gave a name to himself alone, because he alone saw it and because he alone was capable of giving himself a name. For he who does not exist has no name. For what name would one give him who did not exist? Nevertheless, he who exists also with his name and he alone knows it, and to him alone the Father gave a name. The Son is his name. He did not, therefore, keep it secretly hidden, but the son came into existence. He himself gave a name to him. The name, then, is that of the Father, just as the name of the Father is the Son. For otherwise, where would compassion find a name - outside of the Father? But someone will probably say to his companion, "Who would give a name to someone who existed before himself, as if, indeed, children did not receive their name from one of those who gave them birth?"
Above all, then, it is fitting for us to think this point over: What is the name? It is the real name. It is, indeed, the name which came from the Father, for it is he who owns the name. He did not, you see, get the name on loan, as in the case of others because of the form in which each one of them is going to be created. This, then, is the authoritative name. There is no one else to whom he has given it. But it remained unnamed, unuttered, `till the moment when he, who is perfect, pronounced it himself; and it was he alone who was able to pronounce his name and to see it. When it pleased him, then, that his son should be his pronounced name and when he gave this name to him, he who has come from the depth spoke of his secrets, because he knew that the Father was absolute goodness. For this reason, indeed, he sent this particular one in order that he might speak concerning the place and his place of rest from which he had come forth, and that he might glorify the Pleroma, the greatness of his name and the sweetness of his Father.
To my knowledge, I know only a Son of Father of which the name is totally unknown and never revealed:
