The object of faith in the sense of Kant is the postulates of practical reason that is, the immortality of the soul and the existence of God. Together, they constitute the conditions for the possibility of the highest good. Objects of faith are natural, which means that they are constructed by human reason and not revealed by God. On the subject of the immortality of the soul and the existence of God, Kant speaks only from the perspective of pure practical reason. A comparison of the conception of faith of pure practical reason with the conception of Christian faith makes the differences between these two perspectives of faith visible. These differences indicate the specificity of each of them. It is particularly important that rational faith acknowledges the existence of postulates of practical reason, and the supernatural faith concerns the content revealed by God. Faith according to Kant is a natural activity, whereas revealed faith is a supernatural act. Furthermore, rational faith is limited only to the order of practical reason, whereas Christian faith is the activity of reason and will at the same time.
