Thomas Aquinas wrote about the nature and role of government in On Kingship.
Explanation:
Thomas Aquinas was an Italian Catholic priest, theologian and philosopher. He is generally regarded as the foremost of the Roman Catholic theologians. The theological and philosophical doctrine he came to form is called Thomism. He is also regarded as one of the foremost representatives of school politics.
Thomas Aquinas adapted Aristotle's philosophical system to the Christian faith. Aristotle believed that the universe was eternal, something that does not match the revelation of Christianity, which tells of the creation and creator of the universe. In his purely philosophical arguments for the existence of God, Thomas usually assumes that the universe is eternal, since he considered this to be most convincing. That the universe was once created, and thus "began to exist," is something that Thomas cannot philosophically prove, but something that a Christian must believe in accordance with revelation.
