You know better than to say they never had a Mass.
What does Paul talk about? Getting together in homes to celebrate the Lord’s Word and the Eucharist. He doesn’t use those exact words, but it’s there. Please read it again.
There was no mass in the NT church.. the meetings were more similar to a protestant service..there was no altar, or priesthood because the Lords table was not considered a "sacrifice" in the early church ..To have a "sacrifice" one would have an altar and a priest.. Look at the Catholic liturgy.. most of the features that this author tie to the mass were not even written during the lives of the apostles..
They read the leters from the apostles if they had a new one, they would have read the OT and shown Christ , sung and shared the bread and wine..
No Sal the mass came after the death of the apostles.. it was not a part of the NT church.. no priesthood and not altar because there was NO SACRIFICE..that is why there was no role of priest given by God to the new church .
"When the Eucharist came to be regarded as a sacrifice, the role of the bishop took on a priestly dimension. By the third century bishops were considered priests.
Presbyters or elders sometimes substituted for the bishop at the Eucharist. By the end of the third century people all over were using the title 'priest' (hierus in Greek and sacerdos in Latin) for whoever presided at the Eucharist."
