ACC ~ John 17 v3c

CHRIST ASSERTS HIS DEITY

NOVATIAN: If Christ is only a man, why did he lay down for us such a rule of faith as to say, “But this is life eternal, that they may know you the one and true God, and Jesus Christ whom you have sent”? If he had not wanted himself to be understood also as God, why did he add, “And Jesus Christ whom you have sent” unless it is because he wanted to be accepted as also God? Because, if he had not wanted himself to be understood as God, he would have added “and the man Jesus Christ whom you have sent.” But as it is, neither Christ added this nor did he hand down to us that he is only man. Rather, he joined [himself] to God so that he might also by this union be understood as God, as indeed he is. ON THE TRINITY 16.4. [1]

HOPE OF LIFE RESTS IN FATHER AND SON

HILARY OF POITIERS: But in what does eternal life consist? His own words tell us: “That they may know you, the only true God, and Jesus Christ whom you have sent.” Is there any doubt or difficulty here, or any inconsistency? It is life to know the true God. But the bare knowledge of him does not give life. What, then, does he add? “And Jesus Christ whom you have sent.” In you, the only true God, the Son pays the honor due to his Father. By the addition “and Jesus Christ whom you have sent,” he associates himself with the true Godhead. The believer in his confession draws no line between the two, for his hope of life rests in both. And indeed, the true God is inseparable from him whose name follows in the creed. Therefore when we read, “That they may know you, the only true God, and Jesus Christ whom you have sent,” these terms of sender and of sent are not intended, under any semblance of distinction either in name or interval [1] [of time], to convey a difference between the true Godhead of Father and of Son. Rather, they are meant to be a guide to the devout confession of them as begetter and begotten. ON THE TRINITY 3.14. [2]

CATHOLIC FAITH CONFESSES THAT FATHER AND SON ARE TRULY GOD

HILARY OF POITIERS: But perhaps by saying “you the only,” Christ severs himself from communion and unity with God. Yes, but after the words “you the only true God,” does he not immediately continue, “and Jesus Christ whom you have sent”? I appeal to the sense of the reader: what must we believe Christ to be when we are commanded to believe in him also, as well as the Father the only true God? Or, perhaps, if the Father is the only true God, there is no room for Christ to be God. It might be so, if, because there is one God the Father, Christ were not the one Lord. [1] The fact that God the Father is one leaves Christ nonetheless the one Lord. And similarly the Father’s one true Godhead makes Christ nonetheless true God. For we can obtain eternal life only if we believe in Christ, as well as in the only true God. … But the faith of the church, while confessing the only true God the Father, confesses Christ also. It does not confess Christ true God without the Father the only true God. Nor does it confess the Father as the only true God without Christ. It confesses Christ true God, because it confesses the Father the only true God. Thus the fact that God the Father is the only true God constitutes Christ also as true God. The only-begotten God suffered no change of nature by his natural birth. And he who, according to the nature of his divine origin was born God from the living God, is, by the truth of that nature, inalienable from the only true God. ON THE TRINITY 9.34, 36. [2]

KNOWING THE TRINITY

AUGUSTINE: Passing by [the Arians], however, we must see whether, when it is said to the Father, “that they may know you the one true God,” we are forced to understand it as if he wished to intimate that the Father alone is the true God—in case we should not understand any to be God except the three together, the Father, Son and Holy Spirit. Are we therefore, from the testimony of the Lord, both to call the Father the one true God, and the Son the one true God, and the Holy Spirit the one true God, and the Father, the Son, and the Holy Spirit together, that is, the Trinity itself together, not three true Gods but one true God? Or because he added, “And Jesus Christ whom you have sent,” are we to supply “the one true God,” so that the order of the words is this, “That they may know you, and Jesus Christ whom you have sent, the one true God”? Why then did he omit to mention the Holy Spirit? Is it because it follows that whenever we name One who cleaves to One by a harmony so great that through this harmony both are one, this harmony itself must be understood, although it is not mentioned?
