Faith, to the degree that is indeed faith, cannot but be an inner struggle: “I believe; help my unbelief…” (Mk 9:24). Religious feeling, on the contrary, “satisfies” precisely because it is passive, and if it is oriented toward anything, it is primarily toward help and consolation amidst life’s adversities.
Although its subject is always the person, faith is never individualistic, for it is directed to that which is revealed to it as absolute truth, which by its very nature is incapable of being “individual”. Faith therefore invariably requires confession, expression, attraction and conversion of others to itself. Religious feeling, on the contrary, being utterly individualistic, feels itself to be inexpressible and shies away from any attempt at expression and comprehension, as if it were an unnecessary and unhealthy “rationalizing”, which would put “simple faith” at risk of destruction.
True faith aspires to the integral illumination of the entire human composite by subordinating itself to the reason, the will, the whole life. Religious feeling, on the contrary, easily accepts a rupture between religion and life and gets along happily with ideas, convictions, sometimes entire worldviews that are not alien to Christianity but frequently openly contradictory to it.
