Paul's expressions in Romans 2:14,15 about a natural law in the Gentiles, have generated different interpretations regarding the understanding of the salvation of the Gentiles according to the Bible. The question that generates the most discussion is concerning the syntactical function of φύσει in Romans 2:14.

The present article evaluates the interpretations of influential scholars in the debate and shows the interpretative trends concerning the aforementioned issues.
