You have been speaking of the Bible as though it were a book of rules, or manual, i.e. a supreme source of authority on ethical and moral issues, to which it is God's will that all submit and obey. That is an unwise attitude at best, and a potentially tyrannical one. If for the sake of negotiating your own conduct you choose to read the Bible that way, go ahead. But if you demand that other Catholics join you in that style of reading, then you risk looking like a bully.

Interpretation is everything. The Church (i.e. the community of faithful Catholics of all sorts from all centuries) has certain norms for the interpretation of biblical literature, but these are by no means as thorough, absolute and definitive as you imagine.
