Final answer:
The combination of general revelation and special revelation is termed Divine Law. This concept embraces the detection of God's laws through human reason and nature (general revelation) as well as the direct revelation from God (special revelation), a synthesis of views discussed by Aquinas and inherent in Theistic Natural Law Theory.
Step-by-step explanation:
The mix of general revelation and special revelation is known as Divine Law. General revelation refers to the knowledge of God and moral law that can be discerned through nature and human reason. Special revelation refers to the knowledge that cannot be discerned through natural means and must be directly revealed by God, such as through holy scriptures or prophets.
According to medieval philosopher Thomas Aquinas, revelation knowledge plays a crucial role in understanding the divine aspect of laws. These divine laws are part of the Theistic Natural Law Theory where God is seen as the creator of nature, natural laws, and human beings, endowing humans with reason to understand these natural laws. At the same time, God provides special revelation to guide humanity beyond what can be known by reason alone, leading to Divine Law which encompasses both human's ability to reason and God's revelations.
Therefore, when considering whether ethics are an expression of the divine or separate from divine authority, one must consider the role of divine law which incorporates both ethical naturalism and theological moral principles.
