IT is amazing how the Holy Mother Church claims that the basis for all belief is faith. Faith in the irrational, faith in miracles, faith in the most preposterous occurrences imaginable.
And then, because they seem to have an obsession with logic, they have to invent all manner of "logical" constructs: Limbo, Purgatory, a Holy Spirit, a Trinity, papal infallibility, the immaculate conception of the Virgin Mary, who also had to be 100% Pure to be Jesus's mom.
And their reasoning, no matter how silly it might be, can't be debated, once they have established it, because to disbelieve is to lack faith.
