Jesus celebrated the Passover without a lamb and without a temple, yet not without a lamb and not without a temple. He himself was the awaited Lamb, the true Lamb, just as John the Baptist had foretold at the beginning of Jesus' public ministry: "Behold, the Lamb of God, who takes away the sins of the world!" (Jn 1:29).
He himself was the true Temple, the living Temple where God dwells and where we can encounter God and worship him. His Blood, the love of the One who is both Son of God and true man, one of us, is the Blood that can save. His love, that love in which he gave himself freely for us, is what saves us.
Thus, the Cross was at the centre of the new Passover of Jesus. From it came the new gift brought by him, and so it lives on for ever in the Blessed Eucharist in which, down the ages, we can celebrate the new Passover with the Apostles.
From Christ's Cross comes the gift. "No one takes [my life] from me, but I lay it down of my own accord". He now offers it to us.
The paschal haggada, the commemoration of God's saving action, has become a memorial of the Cross and Resurrection of Christ - a memorial that does not simply recall the past but attracts us within the presence of Christ's love.
Thus, the berakah, Israel's prayer of blessing and thanksgiving, has become our Eucharistic celebration in which the Lord blesses our gifts - the bread and wine - to give himself in them.
Let us pray to the Lord that he will help us to understand this marvellous mystery ever more profoundly, to love it more and more, and in it, to love the Lord himself ever more.
Let us pray that he will increasingly draw us to himself with Holy Communion. Let us pray that he will help us not to keep our life for ourselves but to give it to him and thus to work with him so that people may find life: the true life which can only come from the One who himself is the Way, the Truth and the Life.
