Hello. Enoch,
Do you have an example of this?
Going back to my post quoting Justin describing the divine liturgy, here is an even older document peaking of it..
The Didache has no author ascribed to it, but is considered part of the patrimony of the fathers.
Written while some of the apostles were still alive, about the sacrifice of the Eucharist it says:
14:1 And on the Lord's own day gather yourselves together and break bread and give thanks, first confessing your transgressions, that your sacrifice may be pure.
14:2 And let no man, having his dispute with his fellow, join your assembly until they have been reconciled, that your sacrifice may not be defiled;
14:3 for this sacrifice it is that was spoken of by the Lord;
14:4 {In every place and at every time offer Me a pure sacrifice;
14:5 for I am a great king, saith the Lord and My name is wonderful among the nations.}
As we see here, from the very beginning of the Church, the offering of the Eucharist was recognized as the fulfillment of Malachi 1:11
Peace be with you!
