We can't have full knowledge all at once. We must start by believing; then afterwards we may be led on to master the evidence for ourselves.
Thomas AquinasPractical sciences proceed by building up; theoretical science by resolving into components.
Thomas AquinasThe magnitude of the punishment matches the magnitude of the sin. Now a sin that is against God is infinite; the higher the person against whom it is committed, the graver the sin-it is more criminal to strike a head of state than a private citizen-and God is of infinite greatness. Therefore an infinite punishment is deserved for a sin committed against Him.
