John 17
The High Priestly Prayer opens with Jesus lifting his eyes to heaven and praying, "Father, the hour has come; glorify your Son that the Son may glorify you," establishing that Jesus' passion and resurrection constitute mutual glorification between Father and Son. Jesus defines eternal life (zoē aiōnios) not as mere duration but as the relational knowledge of the only true God and Jesus Christ whom he has sent—a definition that reframes eternity as intimate communion and true knowledge rather than temporal endlessness. Jesus prays for the disciples: "I am praying for those whom you have given me, for they are yours," claiming that all whom the Father has given to Jesus remain unalterably his, and asking the Father to protect them in the Father's name and to sanctify them in truth. The prayer extends beyond the immediate disciples to all believers: "I ask not only on behalf of these, but also on behalf of those who will believe in me through their word," encompassing the entire future Church and revealing Jesus' intercessory concern for generations yet unborn. The climactic petition requests that all believers be one—"as you, Father, are in me, and I am in you, may they also be in us"—a unity that testifies to the world that the Father has sent Jesus, and that Jesus has loved them as the Father has loved Jesus. Jesus emphasizes that he has made the Father's name known to them and will continue to do so, so that the love with which the Father loves Jesus may be in them, and Jesus himself in them—establishing the deepest participation in the trinitarian life as the fruit of faith and the Father's will.
