I suspect you know very well that I meant what you refer to as the Roman Catholic Church.
However, there is no such church as 'the Roman Catholic Church'.
The phrase Roman Catholic was invented in the nineteenth century by Protestants as an insult to Catholics.
The official title of what you call the Roman Catholic Church is the Holy Catholic Church. Called by virtually everybody in the world the Catholic church. Which is what I call it.
I am aware that Orthodox (and Protestants) consider themselves the Catholic church. My post was addressed to a Catholic (what you would call a Roman Catholic, he even referred to himself as a Roman Catholic) and is not intended to insult Orthodox Christians.
