If God makes the Pope infallible, why does he need theologians to go into questions first and arrange what he is to define?

Infallibility is not inspiration. If God inspired the Pope in his official teachings there would be no need of human research. But infallibility means that the Pope acts according to all the laws of ordinary prudence, studying and comparing the doctrines of the Church before coming to a decision. When research has concluded, the Pope may decide simply that the matter does not warrant definition. But if he does decide to define a given doctrine, the Holy Spirit will certainly preserve him from any error in doing so. And the defined dogma will owe its infallibility, not to previous human research oi ability, but precisely to the assisting influence of the Holy Spirit
