In the history of Legal Philosophy, natural law concept, reflected in both two first chapters of the Letter of San Pablo to the Romans, means the birth of a new Iusnaturalism. This concept takes roots in the greco-roman classic thought and is based on the new anthropological dimension that provides Christianity. From the Apostle critical view regarding the mosaic law, we can analyse the idea of a nonwritten law that flows from human nature. This law is born in men's heart and works for grace and true justice, represented by Gospel. In addition this natural law constitutes an unequivocal test of the existence of a natural ethics and a theology based on reason.
