Gen 1, 3 God said, "Let there be light"

(Gen 1, 3) God said, "Let there be light"

[3] Then God said, "Let there be light," and there was light.

(CCC 111) But since Sacred Scripture is inspired, there is another and no less important principle of correct interpretation, without which Scripture would remain a dead letter. "Sacred Scripture must be read and interpreted in the light of the same Spirit by whom it was written" (DV 12 § 3). The Second Vatican Council indicates three criteria for interpreting Scripture in accordance with the Spirit who inspired it (Cf. DV 12 § 4). (CCC 292) The Old Testament suggests and the New Covenant reveals the creative action of the Son and the Spirit (Pss 33: 6 104: 30; Gen 1: 2-3) inseparably one with that of the Father. This creative co-operation is clearly affirmed in the Church's rule of faith: "There exists but one God… he is the Father, God, the Creator, the author, the giver of order. He made all things by himself, that is, by his Word and by his Wisdom", "by the Son and the Spirit" who, so to speak, are "his hands" (St. Irenaeus, Adv. haeres. 2, 30, 9; 4, 20, I: PG 7/1, 822, 1032). Creation is the common work of the Holy Trinity. (CCC 159) Faith and science: "Though faith is above reason, there can never be any real discrepancy between faith and reason. Since the same God who reveals mysteries and infuses faith has bestowed the light of reason on the human mind, God cannot deny himself, nor can truth ever contradict truth" (Dei Filius 4: DS 3017). "Consequently, methodical research in all branches of knowledge, provided it is carried out in a truly scientific manner and does not override moral laws, can never conflict with the faith, because the things of the world and the things of faith derive from the same God. The humble and persevering investigator of the secrets of nature is being led, as it were, by the hand of God in spite of himself, for it is God, the conserver of all things, who made them what they are" (GS 36 § 1).
