The Catholic Church believes that anyone can be "saved," but in order to do so they must accept Christ. For those who died following other faiths, this happens at an unspecified time following their death when Christ presents himself to the deceased in all his glory.
So then what rational basis is there for adhering to Catholic doctrines throughout one's lifetime? With nothing tangible to prove or disprove the validity of Catholic thought, one might as well wait until they have died to learn the truth. What benefits other than possible intrinsic satisfaction (which is most likely entirely dependent upon the person rather than the religion itself) come from being a Catholic?
Or am I looking at it the wrong way?
