RC? You mean Catholic Church
Denomination? Since the Catholic Church is the original (first) church founded by Jesus Christ, it is not a denomination. The word denomination means branch of. As the Church founded by Christ, denomination does not apply.
And just because the religion with the biggest army (at that time) makes that claim doesn't make it true...
All one has to do is look at your religion and then look at the scriptures...There are no matches...Your religion is rejected by the scriptures...The scriptures condemn your religion's teaching and even existance...
You may have a legitimate religion but it is not the Christianity of the bible, of Jesus...
Your religion is loaded with forged writings over the centuries...I don't care about your religion...It's going to burn just like the rest of the pagan religions...You people ought to do some serious research before it's too late for you...
