The Catholic Catechism will explain in 2000 laws and 10x the number of each law to rule concerning interpretation.
The question boils down to:
Is the Bible the Word of God?
Is there personal responsibility concerning acceptance of the Word of God?
Can the Word of God be understood by layperson?
Does God desire the layperson to know Him?
Did God die for the layperson?
Who is God?
Jesus?
To judge by what I see on FR, not by a lot of 'em.
