Comparative Study of Aquinas and Kant‘s Narration of Ethics and Theology

Since Kant is a son of his time, his thought is originally rooted in the Enlightenment. The distinction between theoretical and practical reason, formal and material conscientiousness, authentic and doctrinal theodicy, sincerity and falsehood, and finally, historical and moral faith religion, are implications of the court held by Kant for metaphysics. Meanwhile, Kantian distinction between deism and theism in one hand, and inclination toward Job and Christ as the symbols of moral faith of religion in the other hand, can be explained by the German Protestantism of the age of Fredrick the Great and his successor. The theology based on practical reason criticizes rationalism in faith and suggests perception of religion through morality. But, Aquinas as a Christian catholic emphasizes on historical religion, revealed religion, Divine legislation, faith in Divine worship and ecclesiastical faith. Aquinas is the most distinguished supporter of rational theology. However, he believed to other kind of theology named theologia sacrae scripturae or sacred theology which its main subject is Divine beings. The main bases of Aquinas‘s ethics are revelation and foundations of church. Kant, in the contrary, tries to make room for faith inside the realm of morality and speak of practical reason theology through denial of theoretical reason.
