A believer must have “faith”, “hope” in things unseen.

*MASS OF THE LORD’S SUPPER
HOMILY OF HIS HOLINESS BENEDICT XVI
Basilica of St John Lateran
Holy Thursday, 1st April 2010
Dear Brothers and Sisters,
In his Gospel, Saint John, more fully than the other three evangelists, reports in his own distinctive way the farewell discourses of Jesus; they appear as his testament and a synthesis of the core of his message. They are introduced by the washing of feet, in which Jesus’ redemptive ministry on behalf of a humanity needing purification is summed up in this gesture of humility. Jesus’ words end as a prayer, his priestly prayer, whose background exegetes have traced to the ritual of the Jewish feast of Atonement. The significance of that feast and its rituals – the world’s purification and reconciliation with God – is fulfilled in Jesus’ prayer, a prayer which anticipates his Passion and transforms it into a prayer. The priestly prayer thus makes uniquely evident the perpetual mystery of Holy Thursday: the new priesthood of Jesus Christ and its prolongation in the consecration of the Apostles, in the incorporation of the disciples into the Lord’s priesthood. From this inexhaustibly profound text, I would like to select three sayings of Jesus which can lead us more fully into the mystery of Holy Thursday.
First, there are the words: “This is eternal life, that they may know you, the only true God, and Jesus Christ, whom you have sent” (Jn 17:3). Everyone wants to have life. We long for a life which is authentic, complete, worthwhile, full of joy. This yearning for life coexists with a resistance to death, which nonetheless remains unescapable. When Jesus speaks about eternal life, he is referring to real and true life, a life worthy of being lived. He is not simply speaking about life after death. He is talking about authentic life, a life fully alive and thus not subject to death, yet one which can already, and indeed must, begin in this world. Only if we learn even now how to live authentically, if we learn how to live the life which death cannot take away, does the promise of eternity become meaningful. But how does this happen? What is this true and eternal life which death cannot touch? We have heard Jesus’ answer: this is eternal life, that they may know you – God – and the one whom you have sent, Jesus Christ. Much to our surprise, we are told that life is knowledge. This means first of all that life is relationship. No one has life from himself and only for himself. We have it from others and in a relationship with others. If it is a relationship in truth and love, a giving and receiving, it gives fullness to life and makes it beautiful. But for that very reason, the destruction of that relationship by death can be especially painful, it can put life itself in question. Only a relationship with the One who is himself Life can preserve my life beyond the floodwaters of death, can bring me through them alive. Already in Greek philosophy we encounter the idea that man can find eternal life if he clings to what is indestructible – to truth, which is eternal. He needs, as it were, to be full of truth in order to bear within himself the stuff of eternity. But only if truth is a Person, can it lead me through the night of death. We cling to God – to Jesus Christ the Risen One. And thus we are led by the One who is himself Life. In this relationship we too live by passing through death, since we are not forsaken by the One who is himself Life.
But let us return to Jesus’s words – this is eternal life: that they know you and the One whom you have sent. Knowledge of God becomes eternal life. Clearly “knowledge” here means something more than mere factual knowledge, as, for example, when we know that a famous person has died or a discovery was made. Knowing, in the language of sacred Scripture, is an interior becoming one with the other. Knowing God, knowing Christ, always means loving him, becoming, in a sense, one with him by virtue of that knowledge and love. Our life becomes authentic and true life, and thus eternal life, when we know the One who is the source of all being and all life. And so Jesus’ words become a summons: let us become friends of Jesus, let us try to know him all the more! Let us live in dialogue with him! Let us learn from him how to live aright, let us be his witnesses! Then we become people who love and then we act aright. Then we are truly alive.
Twice in the course of the priestly prayer Jesus speaks of revealing God’s name. “I have made your name known to those whom you gave me from the world” (v. 6). “I have made your name known to them, and I will make it known, so that the love with which you have loved me may be in them, and I in them” (v. 26)*. . . .
