In Scripture the word nature expresses the orderly and usual course of things established in the world. St. Paul says, to ingraft a good olive tree into a wild olive is contrary to nature, Romans 11:24; the customary order of nature is thereby in some measure inverted. Nature is also put for natural descent: "We who are Jews by nature," by birth, "and not Gentiles," Galatians 2:15 . "We were by nature the children of wrath," Ephesians 2:3 . Nature also denotes common sense, natural instinct: "Doth not even nature itself teach you, that if a man have long hair, it is a shame to him?" 1 Corinthians 11:14 .
