There you have made the crucial distinction to support what I have been saying all along! There is only one United Methodist Church. There is only one Roman Catholic Church or you could even say there is only one Catholic Church in communion with the Bishop of Rome.
There ARE several Methodist churches and there are several Catholic churches as well.
You just refuse to learn about Catholicism. There are several rites in the Catholic Church, the Latin (Roman) Rite (Roman Catholic) being one of them. All Catholics are in full communion with the Catholic Church. Rite doesn’t refer to different beliefs. All are part of the Catholic Church.
You seem to think that these different rites are like Protestant denominations that break off from one another over doctrinal differences of opinion. Not true of Catholic rites. All Catholics are in full communion. We all share one set of beliefs.
Any church which is not in full communion, no matter what they call themselves, no matter where they come from, is not a Catholic denomination, because there is no such thing as a Catholic denomination. Again, Catholic rites are not the same as denominations, since all Catholic churches share the same set of beliefs and are in full communion with each other and the whole Catholic Church.
Your church is either a Catholic church - in full communion with the Catholic Church - or it isn’t. Calling it Catholic doesn’t make it Catholic. There are no denominations (off-shoots with differing beliefs) within Catholicism. I can call myself a Smith. Doesn’t make me a Smith.
All Christians are in some kind of communion with the Catholic Church, but it’s not full communion. For a church to be Catholic, it must be in full communion with the Catholic Church.
If you refuse to learn this very simple fact, you will continue to mistakenly believe that anyone calling their church “Catholic” is a denomination of the true Catholic Church.
There are no denominations within the Catholic Church, only without.
