“The heavens shew forth the glory of God, and the firmament declareth the work of his hands.” (Psalm xviii, 1)

“But all men are vain… who by these good things that are seen, could not understand him that is, neither by attending to the works have acknowledged who was the workman… let them know how much the Lord of them is more beautiful than they: for the first author of beauty made all those things. Or if they admired their power, and their effects, let them understand by them, that he that made them, is mightier than they: For by the greatness of the beauty, and of the creature, the creator of them may be seen, so as to be known thereby. (Wisdom xiii, 1, 3-5)

“Sciences are differentiated according to the various means through which knowledge is obtained. For the astronomer and the physicist both may prove the same conclusion: that the earth, for instance, is round: the astronomer by means of mathematics (i.e. abstracting from matter), but the physicist by means of matter itself. Hence there is no reason why those things which may be learned from philosophical science, so far as they can be known by natural reason, may not also be taught us by another science so far as they fall within revelation.” (Saint Thomas Aquinas, Summa Theologica, 1a 1ae, q.1, art. 1, ad2)

“By enduring agreement the Catholic Church has held and holds that there is a twofold order of knowledge… [I]n addition to things to which natural reason can attain, mysteries hidden in God are proposed to us for belief which, had they not been divinely revealed, could not become known… [A]lthough faith is above reason, nevertheless, between faith and reason no true dissension can ever exist, since the same God, who reveals mysteries and infuses faith, has bestowed on the human soul the light of reason; moreover, God cannot deny Himself, nor ever contradict truth with truth…” (First Vatican Ecumenical Council, Dogmatic Constitution “Dei Filius”, iv)
