Are you prepared to prove that all your "rich" tradition came from Scripture and/or an Apostle?
God has blessed the Roman Catholic Church as being the largest branch of Christianity (although we don't consider ourselves "a branch of Christianity") - there are over 1.086 billion baptised members around the globe. Our traditions as a people are both religious and cultural. I can't vouch for the traditions of all those people around the world
Although a Catholic teaching may not be plainly stated in the Bible, like "The Trinity", nothing that the Catholic Church teaches contradicts the Bible. There are however many so-called teachings that others attribute to the Catholic church that are false.
