At the first Passover, when the dead lamb’s blood was dripping from the doorpost and lintel, and the dead flesh of the lamb was in the stomachs of the Jews, the angel went by the house and passed by, saying, “death already has been here, no need for me to stop at this house.”
At the new covenant, we eat the flesh of the Lamb of God, and also drink his blood.
Since the Father and Son eternally pour out themselves, their whole being, into one another (the Holy Spirit), we now can take part in this, since we have consumed this Bread from Heaven, and this Living Water, his blood.
Jesus gave his life to give us food to eat and drink to drink - so that in the eternal Love of the Father, when he pours his whole being into the Son, he now does it where his Son’s Body is (which we have consumed and which body we now are - we are the Body of Christ because what we eat we have become), and we now participate in the reciprocation of pouring life into one another that happens in God, in the Trinity. We are participating in the Trinity. In this New Passover, God stops at the house where, under the “roof” is the Body and Blood of the Sacrifice, so that he can pour his life into this Body and Blood.
In eternity, the Father and Son can pour their whole being into each other eternally without ever running out of love to give. Eternal reciprocity of Self, of Love, into the other for the other to have.
Creating us, God poured his whole being into each and all of us.
In Justice of reciprocity, as humans, when we pour our whole being out by living our lives, we are dead.
There is justice, but we are dead - no longer present to receive love from God eternally (our sin left us in this boat).
But Jesus, being Son of God and Son of Man, dying as a man poured out his human life, and gave us his flesh to consume, and then still being Divine, received the Love of his Father, even in his Body, and in us who consume his Body and Blood. He sees the body of his Son in us and he says, “Here is my Son whom I love, Here is my Love, my Spirit, my Son - arise.” And we are now eternally participating in the love of God, in the Life of God.
When we die, it is justice of giving our life back to God who gave us his life so we could BE.
When we eat this bread and drink this cup, we are granted grace to do eternal Justice, eternal reciprocal Love, with God - eternally giving our being to him and his creatures, and eternally receiving his Life.
