Christ assumed human flesh in order to give that flesh for us, and give that flesh to us. The Eucharistic liturgy is a sacrificial covenant meal. It renews a covenant, and every covenant seals a family bond. As the Son of God became human, so we become divine — “sons in the Son,” to use the favorite phrase of the Church Fathers.
Q: Who, then, is a member of the family?
I believe that will be a key consideration of Benedict’s pontificate. He has already demonstrated his eagerness for ecumenical dialogue. If he does no more than continue the work he began as a cardinal, he will articulate the doctrine of the Eucharist in powerful biblical terms, which will be powerfully persuasive to Protestants.
The heavenly liturgy is the key to understanding the biblical books of Hebrews and Revelation. And the experience of liturgy is key to understanding much of the Bible — both the Old and New Testaments.
What Leviticus and Deuteronomy were to the Old Covenant, Hebrews and Revelation are to the New Covenant. Without a knowledge and experience of the liturgy, so much of the content of these books is inaccessible to us.
