Final answer:
The question explores the intersection of divine will and moral law, referencing Kant's categorical imperative and its rational basis for ethics, as well as Aquinas's integration of divine command with rational understanding of natural laws.
Step-by-step explanation:
The relationship between divine will and moral law within teleological or natural-law ethics suggests that (A) there may be a divine purpose alongside (B) purposes defined for humanity. This concept is closely linked to various ethical frameworks, such as deontological ethics, as championed by Immanuel Kant, who posited that moral actions are those which can be universalized through the categorical imperative.
Kant's approach avoids viewing morality from a God-like objective standpoint, focusing instead on rational universality. On the other hand, philosophers like Thomas Aquinas in his discussion of eternal, natural, human, and divine laws, bridge the gap between divine commands and rationality by suggesting that human reason can discern natural laws. These natural laws are part of the divine order and indicate that moral values have an objective basis in the natural world, aligning with ethical naturalism.
