The Eucharist is a mystery not because it is mysterious, but because it is a sign of God’s secret purpose, which is to unite all things in Christ. In the Eucharist we celebrate that the mess of human history, with its violence and sin, its wars and genocides, is somehow, in ways that we cannot now understand, on its way to the kingdom. It is God’s will that we be gathered into unity, reconciled with each other. And so we begin the Eucharist asking the forgiveness of our brothers and sisters, the angels and the saints, the whole vast community of the kingdom. It is a sign that we are willing to be gathered into God’s peace with the rest of creation.
