Paul calls the Gentiles Christians because he is the teacher of the Gentiles, as he says elsewhere: “For I speak to you Gentiles.” These people are uncircumcised and do not keep new moons or the sabbath or the law of foods, yet under the guidance of nature they believe in God and in Christ, i.e., in the Father and the Son. To keep the law is to acknowledge the God who gives the law. This is the first part of wisdom: to stand in awe of God the Father, from whom all things come, and the Lord Jesus his Son, through whom all things come. Therefore nature itself acknowledges its Creator by its own judgment, not by the law but by reason, for the creature recognizes its Maker in itself. Commentary on Paul’s Epistles.
