1 Corinthians 10:15-17
New Revised Standard Version Updated Edition
15 I speak as to sensible people; judge for yourselves what I say. 16 The cup of blessing that we bless, is it not a sharing in the blood of Christ? The bread that we break, is it not a sharing in the body of Christ? 17 Because there is one bread, we who are many are one body, for we all partake of the one bread.
