This is not a forum to engage in an exegetical discourse of scripture. Colleges and universities have there year degrees on this and doctoral degrees as well.
Protestants are well know for throwing out bits and pieces of scripture to advance their “own” theology. This what David Koresh and Jim Jones did, as do thousands of others street-pastors who pick up a Bible and then like TD Jakes etc thump around their interpretations. If you want to test and debate your points of view, I suggest you either pick up a book by Benedict XVI or as is so convenient these days you may visit any number of Catholic websites. For starters, I suggest:
www.Catholicanswers.com

I'll stop refuting error here when people stop posting it. Meanwhile:
2Ti 3:13-17 But evil men and seducers shall wax worse and worse, deceiving, and being deceived. (14) But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them; (15) And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus. (16) All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: (17) That the man of God may be perfect, throughly furnished unto all good works.
If God's own apostle says it's profitable, who am I to argue?
BTW, that clause where we're just supposed to sit back and let the academic elites duke it out? You may have that in your Bible. It's not in mine.
Peace,
