The intellect in faith is capable of an insight of wisdom grasping the heart of the matter. It is a faith putting ourselves at our Master's feet. Faith opens our intellect and heart to the Word of Jesus, who aids us in the grasping of the mystery. The modern sciences require a Cartesian, judgmental approach. Moral theology requires us not to judge but to submit and to be led.
Cartesian science looks at things as objects, looking from the outside.
To look from the inside, faith confronts us and allows us to study the interiority of human action. Saint Thomas in the prologue of the prima secundae, has the intuition of the image of man's mirroring God when he acts from the intellect and will and mature free choice.
