Apostolic Fathers: Didache
Chapter 14 1 Come together each Lord's day to break bread and give thanks. Confess before each other your transgressions. Your offering should be clean. 2 Let no one disputing with his neighbor join your gathering until they are reconciled. Your offering should not be defiled. 3 For the Lord proclaims, “In every place and time offer to Me a clean offering, because I am the great King,” says the Lord, “and My name will be praised among the nations.” Each congregation is encouraged to partake of the Eucharist every Sunday. The outline of the Divine Service encourages this as well. We come together to confess our sins, offer our firstfruits and give thanks by breaking bread together. Jesus' statement about fellowship is referenced: “If you are offering your gift at the altar and there remember that your brother has something against you, leave your gift there before the altar and go. First be reconciled to your brother, and then come and offer your gift” (Matthew 5:23-24). God does not accept every offering (Genesis 4:3-5; Acts 5:1-11). God desires clean offerings so that His name may be glorified in our offering (Malachi 1:11). Thoughtless offerings cast dispersion on God's name in the heart of the one offering as well as those receiving the offering. Offerings are to be made out of a heart free from malice, envy and strife.
