Has the Catechism been declared dogma?
The objection you guys are trying to raise, that not every Bible verse has been infallibly interpreted and defined, is silly. Infallible teaching is traditionally structured in the negative, first of all: "This is what you may *not* believe and still be a Catholic."
Trying to exhaustively define the whole meaning of even a single Scripture verse would be a bad idea; much of Scripture has multiple senses and nuances of understanding. Why tie exegetes' hands like that? No, the Church tells them how *not* to interpret it, and then gives them their freedom.
