FK: "But this does tell me something. Does it tell you anything? :)"
Let me guess: it's a riddle?
It's the same idea as what I just posted. :) If the Church does not teach everything that Paul taught, then the Church purposely does not teach all of scripture. By definition, this means that the Church does not accept all of the inspired word of God. I have been contending this for some time.
The Church does teach everything +Paul taught, except with a different interpretation than the +Paul taught by the Protestants.
Herein lies the rub, FK. Everyone who calls on Christ's name claims to teach the 'right' faith. God is a riddle we cannot solve, but if God revealed Himself to men we presume that He did so that men would 'know' Him and would know what God expects from us.
That is not the case. Many if not all those who teach anything the Bible says claim to have the Holy Spirit as a Guide. That's not possible, because the teachings differ so much they are unrecognizable in some cases.
What could be the cause of that discord? The Holy Spirit teaches everyone something else or men fail to understand the essence of faith? I would say the latter.
Just because the same-minded people or even individual readers agree with themselves doesn't mean they are right! The Old World Order was based on the geocentric theory (earth at the center, everything revolves around us) based on the Bible (man is God's central creation), philosophy (Aristotle) and science (Ptolemy).
They all came, independently, to the same concordant conclusion: earth is at the center of all creation and everytyhing revolves around us. The knowledge couldn't be more solid than the concordance of three powerful fields of man's knowledge coming to the same conclusion independent of each other! Yet, they were wrong.
Western Christian 'confidence' is an expression of this rationalistic dogmatic mindset that believes man can solve every enigma and explain everything through reason. That might be true if man (a) had all the information necessary and (b) the capacity to process it. We don't. So, no matter what we do, we can only 'hope' in God's mercy because we can never be sure that we really 'know' anything for certain.
