Maybe you didn't get the memo, there was no 'Mass' for the first centuries of Christianity.
There were many false books competing with Christianity, but the local churches were able to filter them out.
In the later centuries, it was recognized what had been mostly accepted by individual churches.
False churches accepted apocyrpha books in both the Old and New Testament.
Ever figure out what Jn.15:2 means?
"Breaking the Bread" is the celebration of the Eucharist - what we call the "Mass". It's been going on since the very beginning of Christianity.
There were many false books competing with Christianity, but the local churches were able to filter them out.
That is not the way Christian history relates how the Canon was formed. I don't know where you get your information, but a number of letters were read at the MASS that today are not part of what we call "Scripture". One example is the first letter of Clement of Rome to the Corinthians.
False churches accepted apocyrpha books in both the Old and New Testament.
False Churches later denied what was accepted by the Universal Church. What happened? Those cats from 1000 years later suddenly have a "revelation"?
Ever figure out what Jn.15:2 means?
I'm sure you and your self-proclaimed infallibility will soon tell me...
