It is not the "Rome" that you state.
It is the Catholic Church throughout the ENTIRE world. Here is a link to all the different rites, including the Latin Rite, which you call, "Rome" or RC.
The Rites of the Catholic Church [Catholic Caucus]
One and Many Churches (origins of the Church)
THE RITES OF THE CATHOLIC CHURCH -- There are many!
(Cardinal) Newman on Rites and Ceremonies
If its not the number than offend then its the term, but “Rome” is short for the Roman Catholic, or “Roman church” as their headwaters is in Rome, their center of unity, likewise “Washington says” refers to what America says.
If you do not even allow anything more than “Catholic” so that even “Roman church” is disallowed, then that is another story.
Such is typically necessary to differentiate btwn those who defend a church that holds to papal infallibility, and its supremacy magisterial authority, and RC purgatory and indulgences, the Immaculate Conception, which the EOs reject or differ on, and also claim to be the OTC, or other things some Catholics differ on.
The Orthodox Church opposes the Roman doctrines of universal papal jurisdiction, papal infallibility, purgatory, and the Immaculate Conception precisely because they are untraditional.” — Clark Carlton, THE WAY: What Every Protestant Should Know About the Orthodox Church, 1997, p 135.
“Also, the Orthodox Church does not believe in indulgences as remissions from purgatoral punishment. Both purgatory and indulgences are inter-corrolated theories, unwitnessed in the Bible or in the Ancient Church, and when they were enforced and applied they brought about evil practices at the expense of the prevailing Truths of the Church. If Almighty God in His merciful loving-kindness changes the dreadful situation of the sinner, it is unknown to the Church of Christ. The Church lived for fifteen hundred years without such a theory.” — http://www.goarch.org/ourfaith/ourfaith7076
In the Nicene Creed of faith our Church is described as the “One, Holy Catholic and Apostolic Church”: “One” because there can only be one true Church with one head Who is Christ... Each of these titles is limiting in some respects, since they define Christians belonging to particular historical or regional Churches of the Orthodox communion...http://www.goarch.org/archdiocese/)
Then there are those who attempt to join together all Christian religions into one faith. They would be horrified at the idea of a service with Hindus and Christians celebrating together, yet they do not bat an eyelash at the idea of Orthodox celebrating with Roman Catholics, who with no authority broke off from the Church close to a thousand years ago.
