Day 319 - John 17

The one who believes in the Son believes also in the Father, for he believes in what is proper to the Father’s essence. And thus the faith is one in one God. And the one who worships and honors the Son, in the Son worships and honors the Father. For the Godhead is one. And therefore the honor is one and the worship is one that is paid to the Father in and through the Son. And the one who worships in this way worships one God. For there is one God and none other … Therefore, these passages [Mrk 12:29; Exo 3:14; Deu 32:39 (LXX); Isa 44:6 as well as Jhn 17:2.] are not written in order to deny the Son or with reference to him at all, but to overthrow falsehood. Notice how God did not speak these kinds of words to Adam at the beginning, although his Word was with him by whom all things came to be. For there was no need before idols came in. But when human beings made insurrection against the truth and named for themselves gods such as they did, then the need arose for such words in order to deny the gods that were not … If then the Father is called the only true God, this is said not to the denial of him who said, “I am the Truth” [Jhn 14:6.] but of those … who by nature are not true, as the Father and his Word are. And so the Lord himself added at once, “And Jesus Christ whom you have sent.” Now had he been a creature, he would not have added this and ranked himself with his creator. For what fellowship is there between the True and the not true? But as it is, by including himself with the Father, he has shown that he is of the Father’s nature. And he has given us to know that of the true Father he is true offspring—St Athanasius the Apostolic
