The church gathered is Jesus’s bride. One of the aspects of Lord’s-day worship is that Jesus holds tryst with his bride.
Seemingly every other page of the Bible has something to do with food. Food is the chief avenue for the consummation of fellowship; if we are what we eat, then when we eat together, we become more united. We have already seen Jesus’s desire to eat with his church. Ahashuerus prepares a feast for his people (Esther 1). Esther prepares feasts for Ahashuerus (Esther 5, 7). Joseph prepares a table for his brothers (Gen. 43). Jesus prepares breakfast for his disciples, then instructs them to feed his flock (John 21). Melchizedek prepares a meal (of bread and wine!) for Abraham (Gen. 14), and Abraham later prepares a meal for Jesus and two angels (Gen. 18). In spite of their differences, Jacob and Laban share a meal to seal their covenant (Gen. 31:54). Jesus prepares a table for us in the very presence of our enemies (Ps. 23). Solomon and his bride banquet with and feast upon one another. In a sense, Jesus eats us into his body (Rev. 3:16, also considering we are the loaves of Lev. 24 and 1 Cor. 10), and we eat Jesus (John 6).
Thus, weekly communion: every tryst has its morsels and wine (e.g., Esther 5, 7), and every reunion its repast. Jesus provides not only enough wine when the groom meets with the bride, but also the best wine (John 2).
