If we DO 'need' to know; is that not an indictment against the RCC?
Doesn't IT claim that it had the Authority and Power to assemble the BIBLE as we have it today?
WHY did they LEAVE THIS STUFF OUT when they had the only game in town for 1500 or so years?
Questions that it appears Catholics have never thought through.
If that is an example of how the Holy Spirit has guided their magisterium in assembling the Bible that left so much critical information out, then I think they need to rethink their confidence in said magisterium.
