Augustine of Hippo
If it was His intention for the statement, "I have revealed Your name to the men whom You gave Me from the world," to be grasped by everyone, including those who have yet to come to faith in Him and would be part of His universal Church, encompassing all nations—of which it is sung in the Psalm, "I will confess Thee in the great Church" (cf. Psalm 34:18)—then it is clear that this is the exaltation by which the Son honors the Father, declaring His name to all peoples and multiple generations. His declaration, "I have revealed Thy name to the men whom Thou hast given Me out of the world," mirrors an earlier proclamation, "I have glorified Thee on earth" (John 17:4). In both instances, He employs the past tense rather than the future, reflecting His awareness that this was divinely ordained and affirming that He had accomplished what He was certain would come to pass.
Do you know who the Only Begotten is? Consider these words: I will confess to You, O Lord, in a great assembly; in a weighty nation I will praise You. (Ps. 34:18). Truly, he declares, I confess unto You: for while the multitude may confess, not all within it offer praise to God. The entire assembly hears our confession, but not every voice among them glorifies Him. Within this multitude, that is, within the Church that is dispersed, both tares and wheat exist: the tares are carried away, while the wheat endures. Therefore, among a steadfast people, I will bring You praise. In such a resilient community, which the winds of temptation do not sweep away, God is exalted. For among the chaff, He is continually blasphemed.
