Regarding arguing whether or not early Christian worship services should be called “Mass” — Oy Vey!
As a Jewish acquaintance told a Catholic friend of mine: “I see the traditional synagogue worship service in both the Mass and many Protestant worship services.”
It just struck me that I must agree with Mom MD that Saint Peter could NOT have held Mass, especially as we know it.
Why? Because the Mass and even Protestant services include reading from the books of the New Testament; these books would not have been written and codified when St Peter was spreading the faith and holding services, therefore he could not have been holding Mass.
The above said in total sarcasm directed to the line of arguments that developed about it.
