Byzantine rite in Catholicsm, which is Catholic but not Roman Catholic

Not correct. Byzantine Greeks and Slavs are Romans. They are not Latins. Everyone in the Catholic Church is Roman.

Thanks for the correction. You are a heck of a resource for Catholic knowledge.

You might want to talk with a Byzantine Catholic about that. They are in communion with the pope, but they are not Roman Catholic.

Hermann, you are usually pretty knowledgeable about things, but on this one you need to check yourself. Unless you are reaching for an older definition of Roman that encompasses the Orthodox, Copts, ect. Byzantines are not Roman. There are in union with Rome, but that puts them out of union with their natural patriarch in the See of Constantinople until there is a reunification of the Church and the schism between Constantinople and Rome is ended.

[Notwithstanding]

I believe the common nomenclature and termniology among papal Catholics of all stripes is as follows:

"Roman" genrally refers to either:

a) the See of Peter in Rome (and all those who consider him to be the authoritative shepherd for all); or

b) the Latin rites for Mass (the moset common rite is the Roman rite)

"Catholic Church" is the title of those united under the Holy See in the Vatican.

"Latin" is generally used to describe the liturgical rite that most Catholics follow (even when it is in the vernacular). This is often also called "Roman" (as I noted above).

I know that Maronites (Lebanese Catholics) do not use the Latin or Roman rite - instead they use the Maronite rite (a very different Mass - not simply a different language).

I think it is the same for Byzantine Catholics - they follow Byzantine rite (again, a very different Mass).

All of these rites are valid Catholic rites and all of these groups submit to the authroity fo the Pope.
