All things excellent are as difficult as they are rare.

Schisms do not originate in a love of truth, which is a source of courtesy and gentleness, but rather in an inordinate desire for supremacy.

Everything great is just as difficult to realize as it is rare to find.

Desire nothing for yourself, which you do not desire for others.

The most tyrannical of governments are those which make crimes of opinions, for everyone has an inalienable right to his thoughts.

The more a government strives to curtail freedom of speech, the more obstinately is it resisted; not indeed by the avaricious, ... but by those whom good education, sound morality, and virtue have rendered more free.

I do not believe anyone has reached such perfection, surpassing all others, except Christ, to whom God immediately revealed - without words or visions - the conditions which lead to salvation.
