Editing Divine command theory (section)

===Thomas Aquinas===
{{Roman Catholic Church}}
Whilst [[Thomas Aquinas]], as a natural law theorist, is generally seen as holding that morality is not willed by God,<ref>{{Cite book|chapter-url=https://plato.stanford.edu/entries/aquinas/#NatLaw|title = The Stanford Encyclopedia of Philosophy|chapter = Saint Thomas Aquinas|year = 2018|publisher = Metaphysics Research Lab, Stanford University}}</ref> Kelly James Clark and Anne Poortenga have presented a defence of divine command theory based on Aquinas' moral theory. Aquinas proposed a theory of natural law which asserted that something is moral if it works towards the purpose of human existence, and so human nature can determine what is moral. Clark and Poortenga argued that God created human nature and thus commanded a certain morality; hence he cannot arbitrarily change what is right or wrong for humans.<ref name=austin/>
