A term applied to various theories that claim that faith is the only or ultimate source of all knowledge of God and spiritual things. The name was originally coined by followers of Kant (1724-1804) and Schleiermacher (1768 -1834), both of whom denied the capacity of reason to know God or the moral law with certainty. (Etym. Latin fides, belief; habit of faith; object of faith.)
