Well, that pretty much removes any basis for Catholics complaining about the multitude of *Protestant* denominations then.
Because the reason for so many denominations is not necessarily differences in theology. Most of them are far closer theologically to each other than many of the Catholic rites are.
But, you already agreed that rites are not basically theologically different. They are more geographical and culturally different. By the way there was a great deal of duplication in your list.
By the way, as an Orthodox Christian, I'm not defending Rome, just trying to clarify things.
Maybe this will help. Two Orthodox jurisdictions in the US, the Antiochian Archdiocese and ROCOR (the Russian Church Outside Russia) have a small Western Rite. The services in those parishes can look like Roman Catholic or Anglican services depending on the liturgy used BUT the theology is identical to standard Orthodox teaching. Those rites are under the same governance as are the Eastern rites in the same jurisdictions.
