The Mass in its current form goes back to the 1st century.
What sort of worship dost thou engage in? Art thou familiar with the contours of thy navel?
You really believe that stuff?
Not hardly. The Eucharist was not seen as an onging sacrifice at all, that was a much later development in the western church after Theodosius I made Christianity the religion of the empire.
What sort of worship dost thou engage in?
The same as is described in the Didache.
Chapter 9. The Eucharist. Now concerning the Eucharist, give thanks this way. First, concerning the cup:
We thank thee, our Father, for the holy vine of David Thy servant, which You madest known to us through Jesus Thy Servant; to Thee be the glory for ever..
Nothing there about the wine being the actual blood of Christ.
And concerning the broken bread:
We thank Thee, our Father, for the life and knowledge which You madest known to us through Jesus Thy Servant; to Thee be the glory for ever. Even as this broken bread was scattered over the hills, and was gathered together and became one, so let Thy Church be gathered together from the ends of the earth into Thy kingdom; for Thine is the glory and the power through Jesus Christ for ever..
Nothing about the bread being the actual, literal flesh of Christ.
But let no one eat or drink of your Eucharist, unless they have been baptized into the name of the Lord; for concerning this also the Lord has said, "Give not that which is holy to the dogs."
Chapter 10. Prayer after Communion. But after you are filled, give thanks this way:
We thank Thee, holy Father, for Thy holy name which You didst cause to tabernacle in our hearts, and for the knowledge and faith and immortality, which You modest known to us through Jesus Thy Servant; to Thee be the glory for ever. Thou, Master almighty, didst create all things for Thy name's sake; You gavest food and drink to men for enjoyment, that they might give thanks to Thee; but to us You didst freely give SPIRITUAL food and drink and life eternal through Thy Servant. Before all things we thank Thee that You are mighty; to Thee be the glory for ever. Remember, Lord, Thy Church, to deliver it from all evil and to make it perfect in Thy love, and gather it from the four winds, sanctified for Thy kingdom which Thou have prepared for it; for Thine is the power and the glory for ever. Let grace come, and let this world pass away. Hosanna to the God (Son) of David! If any one is holy, let him come; if any one is not so, let him repent. Maranatha. Amen.
We agree with the Didache that the "cup and bread" are SPIRITUAL food, not the actual, literal blood and flesh of Jesus as Rome later came to believe.
