Are you prepared to say every message by every priest every service has been approved by Rome and is identical?
Are you prepared to say every Catholic Bible study (if y'all have those) has been approved by Rome?
Didn't think so. We see the differences in Catholic beliefs on these very threads.
You miss the point. Of course not every statement.
But we have a Credo, the Mass and the Eucharist. Everything else called “Christian” is useless because everything else called “Christian” admits to 30, 000 denominations or varieties of Christianity. This is why you have so many pre-eminent Lutheran theologians jumping ship and coming on board the one truth Church founded b Christ.
