On the Lord's day, when you gather together, break bread and give thanks, confessing your sins so that your sacrifice may be pure.
Whoever has doubts should not join in your fellowship meals, until they resolve their doubts; otherwise your sacrifices may be defiled.
For this is what the Lord has said, "In every place and at all times, offer me a pure offering, for I am a great King and my name is revered among the nations.”
