Divine law is any law that comes directly from the "will of God", in contrast to man-made law. Unlike natural law, which is independent of human beings, divine laws are totally dependent on human narrators and closely related to different cultures; they may change in human perception in time through new revelation, however, divine laws are eternal and constant, not subject to change. Divine laws are contained in sacred religious texts such as the Torah, the Holy Bible, and Quran.
Aquinas
In Thomas Aquinas's Treatise on Law, divine law comes only from revelation or scripture, hence biblical law, and is necessary for human salvation. According to Aquinas, divine law must not be confused with natural law. Divine law is mainly and mostly natural law, but it can also be positive law.
