[Christianity] endeavors equally to establish these two things: that God has set up in the Church visible signs to make himself known to those who should seek him sincerely, and that he has nevertheless so disguised them that he will only be perceived by those who seek him with all their heart.
Blaise PascalThere are three means of believing--by inspiration, by reason, and by custom. Christianity, which is the only rational institution, does yet admit none for its sons who do not believe by inspiration. Nor does it injure reason or custom, or debar them of their proper force; on the contrary, it directs us to open our minds by the proofs of the former, and to confirm our minds by the authority of the latter.
