Floo, Orhtodox are quite distinct from Catholics.
What you'd call Roman Catholics are Catholics with a big C. Before Catholicism there was Orhodoxy. There are also different branches of Orhtooxy.
Speaking of catholic tradition, eg the Anglican, Episcopal, Methodist or Orthodox, you use lower case c. It means 'universal' and when speaking of Christian faith,applies to all whatever their differences.
You come across as prejudiced against Catholics but when you say ad-o is a Catholic you show you don't know that much & its not fair. If you engage in debate with people of other faiths or traditions you owe it to them to have some reliable information from which to start.
