To my knowledge there is no total Catholic "official" interpretation of scripture.You misunderstand where a Catholic must defer. If the Church hasnt spoken on an issue, the Catholic is as free to hold his own various opinions as the Protestant is. When you consider that it is the Word of an infinite God, I think you have to assume that a truly "total interpretation of Scripture" isn't really possible for a human.Since the Catholic must defer to the "authority" for the authentic interpretation, what must he do?

Catholic Catechism
100 The task of interpreting the Word of God authentically has been entrusted solely to the Magisterium of the Church, that is, to the Pope and to the bishops in communion with him.
How many issues can a man discover that if taken to its end conclusions wont clash with your Church doctrine?
If a man is guided by Gods Spirit to a truth that differs from that of the magisterium, he must either abandon his new truth or never mention it anyone else, but he may then submit it to the hierarchy for their evaluation, which will be rejected if it goes against Church doctrine.
What would motivate a Catholic to use Gods Holy Spirit when anything hes shown will be shot down by his Church leaders?
