I don’t understand being required to believe? Doesn’t true belief need some sort of leap of faith, or divine intervention?
A person, who has been 'properly catechized', will actually 'believe' the correct, Roman Catholic way.
That’s an interesting question and perhaps I’m not understanding it fully but it doesn’t seem to me beliefs require “leaps of faith” (as if there is never a reason to believe in anything other than through an act of the will).
