1 Corinthians 10:16-18

Williams(i) 16 Is not the consecrated cup which we consecrate a sign of our sharing in the blood of Christ? Is not the loaf which we break a sign of our sharing in the body of Christ? 17 Because there is only one loaf, so we, though many, are only one body, for we all partake of one loaf. 18 Look at the Israelites in their practices. Are not those who eat the sacrifices in spiritual fellowship with the altar?
