Since you profess to like the Bible, do you understand the Old Testament? History may not repeat, but it certainly rhymes. So, yet again, we have Israel separating itself from Judah. You are telling me to walk away from Judah and join Israel. And I'm saying: no sale.
What you practice and what you believe is entirely up to you. However, consider the possibility that those who are objective in their approach to what God wants us to believe and practice might find it at least a tiny bit amusing that of all the the vast areas of theology that Catholics engage in that are either not mentioned in the Bible or are outright prohibited, the thing that has Catholics all aroused these days is the current situation regarding their Mass in the Latin language.
Israel did not separate itself from Judah, it was Jehovah that divided the kingdom into two, due to the disobedience and idolatry of Solomon. (1 Kings 11:11-13)
