What is a Sacrament? 1 Corinthians 10:16-18
1 Corinthians 10:16–18
[16] The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation 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. [18] Consider the people of Israel: are not those who eat the sacrifices participants in the altar?
