1 Corinthians 11:27-29

Contemporary English Version

²⁷ But if you eat the bread and drink the wine in a way that isn't worthy of the Lord, you sin against his body and blood. ²⁸ This is why you must examine the way you eat and drink. ²⁹ If you fail to understand that you are the body of the Lord, you will condemn yourselves by the way you eat and drink.
