[Writing about the significance of Communion for the early church] This meal was a sign of their reconciliation to God and their membership among the elect who would one day feast together in God’s kingdom, and the intimate fellowship with one another that they experienced around the table was a foretaste, an anticipation, of the union that they would enjoy forever with God. The whole meal was thus both a prophetic symbol of the future and also a means of entering into that future in the present.
