I am not believing what I will...these are doctrines which are not biblical. Your organization promotes errant theology and we are trying to keep the readership here informed about this problem. If you can find any of them in Scripture, feel free to rebut my post.
What makes you think everything is in the Bible? The word “trinity” isn’t in the Bible. The Bible doesn’t say, “Believe the Bible.” Your argument doesn’t hold for basic reasons. The Bible, as a single volume, didn’t exist until over 400 years after the Resurrection. The books of Bible were assembled into the volume, thus impossible to reference themselves as a volume.
Should you choose, you can read any of the number of works, freely available on any number of Catholic websites (Vatican.va, EWTN.com, Catholic.com) that clearly demonstrate the Biblical references for every Catholic belief.
You are free to believe what you want, but that doesn’t mean you are free to tell the Catholic Church what it believes and teaches.
