John 17 has two names. 1. The Priestly Prayer of Jesus. 2. The Prayer of the Hour of Jesus.
Both names ultimately mean the same thing. In Christ’s “Hour,” Judas betrayed Him, like Adam and Eve and all us sinners betrayed Him. Jesus answered this betrayal with His sacrifice. He offered Himself with perfect justice and infinite love, for the salvation of His betrayers.
Christ’s prayer in John 17 reveals that His death involved not just an injustice, not just the wrongful execution of an innocent man. The Priestly Prayer reveals that Jesus’ death was no ‘tragedy.’ Christ took up the cross to make a thoroughly deliberate, wise, and all-knowing religious sacrifice. It was the sacrifice of His divine love: He offered Himself with perfect love to the Father, out of perfect love for us.
Christ’s prayer in John 17 reveals that the Crucified Lamb is the Creator and the Pantocrator, the ruler of everything. We can know Almighty God, and understand His many works, in only one way: By looking at a crucifix.
And this sacrifice, the true Passover sacrifice, is eternal. It happened at one point in time, to be sure, just as Jesus used a particular language and particular words to pray the prayer recorded in John 17. In that particular hour and using those particular words, however, the eternal, omnipotent Love–the unfathomable power that governs everything–revealed Himself.
Jesus’ prayer to the Father, “Consecrate them in truth,” is not one human statement among many. It is not just one audio blip in the endless noise made by fallen man on this earth. It is not just a “tweet” by a Nazarene carpenter.
Consecrate them in truth is the eternal, unchanging divine will. It expresses the groaning of the eternal Spirit in the Heart of Christ, the inexpressible groaning that moved Christ to utter His every word and do His every deed.
The Catechism has six mind-blowingly profound paragraphs on John 17—article 3 of chapter 3 of Part IV. It all may seem way above our pay-grade—until we realize that John 17 and the Our Father are like two sides of the same coin.
The ‘heads’—John 17—belongs to Christ, the Head of the Body. The ‘tails’ is our dearest of all friends, the Our Father. Whenever we celebrate Holy Mass, we have the whole coin.
