1 Corinthians 10:15-17

I know I am writing to thoughtful people, so carefully consider what I say. For when we pray for the blessing of the communion cup, isn’t this our co-participation with the blood of Jesus? And the bread that we distribute, isn’t this the bread of our co-participation with the body of Christ? For although we’re many, we become one loaf of bread and one body as we feast together on one loaf.
