My LORD’s BibleDidache 14
1But on the Lord's day, after that ye have assembled together, break bread and give thanks, having in addition confessed your sins, that your sacrifice may be pure. But let not any one who hath a quarrel with his companion join with you, until they be reconciled, that your sacrifice may not be polluted, for it is that which is spoken of by the Lord. In every place and time offer unto me a pure sacrifice, for I am a great King, saith the Lord, and my name is wonderful among the Gentiles.
