That may be your opinion, but we are VERY 'Bible based'. After all, we're the ones who put it all together in writing for the first time. It didn't spring up, fully formed, during the Reformation.
Just because we have some traditions that are not specified in Scripture, doesn't mean we don't have the Word of God as the basis for all we do.
There is a big difference between an opinion and a fact.
It is a FACT that Catholicism is not Bible based.
Neither is Mormonism. Neither is Jehovah Witnesses ... it’s just one of many perverted Christian beliefs.
The bible itself is evidence of that. Jesus turned to PETER, not to some scripture, and said YOU ARE THE ROCK ON WHICH I WILL BUILD MY CHURCH. Peter was the first pope.
The Bible is useless as a basis for a religion because it is open to interpretation a billion different ways. That's why there are 30k different prot denominations right now.
