We set forth our petitions before God, not in order to make known to Him our needs and desires, but rather so that we ourselves may realize that in these things it is necessary to turn to God for help.
Thomas AquinasFor those with faith, no evidence is necessary; for those without it, no evidence will suffice.
Thomas AquinasThe knowledge of God is the cause of things. For the knowledge of God is to all creatures what the knowledge of the artificer is to things made by his art.
Thomas AquinasClearly the person who accepts the Church as an infallible guide will believe whatever the Church teaches.
Thomas AquinasIf there were some solitary or feral man, the passions of the soul would be sufficient for him; by them he would be conformed to things in order that he might have knowledge of them. But because man is naturally political and social, there is need for one man to make his conceptions known to others, which is done with speech. So significant speech was needed if men were to live together. Which is why those of different tongues do not easily live together.
