Divine law

Divine law comprises any body of law that is perceived as deriving from a transcendent source, such as the will of God or gods - in contrast to man-made law or to secular law. Divine laws are typically perceived as superior to man-made laws, sometimes due to an assumption that their source has resources beyond human knowledge and human reason. Believers in divine laws might accord them greater authority than other laws, for example by assuming that divine law cannot be changed by human authorities.
Divine laws are noted for their apparent inflexibility. Divine laws are often perceived as beyond the authority of humans to change. The introduction of interpretation into divine law is a controversial issue, since believers place high significance on adhering to the law precisely. Opponents to the application of divine law typically deny that it is purely divine and point out human influences in the law. This element of human influence is understood as incorporating some degree of fallibility. These opponents characterize such laws as belonging to a particular cultural tradition. Adherents of divine law, on the other hand, are sometimes reluctant to adapt inflexible divine laws to cultural contexts.
Divine laws are assumed to be transmitted through several mediums, most frequently through time-out-of-mind tradition or through religious texts. Medieval Christianity assumed the existence of three kinds of laws: divine law, natural law, and man-made law. Others, on the other hand, assume that natural law is a subset of divine law delivered through general revelation from a creator deity. Theologians have substantially debated the scope of natural law, with the Enlightenment encouraging greater use of reason and expanding the scope of natural law and marginalizing divine law in a process of secularization. Some people may understand themselves as receiving guidance through prayer or conscience, although the moral authority of these methods of transmission ranks much lower than that of written divine law.
Since the authority of divine law is rooted in its source, the origins and transmission-history of divine law are important.
Conflicts frequently arise between secular understandings of justice or morality and divine law.
Religious law, such as canon law, includes both divine law and additional interpretations, logical extensions, and traditions.

Thomas 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.
