His [Calvin's] religion was demonism. If ever man worshiped a false God, he did. The being described in his five points is ... a demon of malignant spirit. It would be more pardonable to believe in no God at all, than to blaspheme him by the atrocious attributes of Calvin

Shake off all the fears and servile prejudices under which weak minds are servilely crouched. Fix reason firmly in her seat, and call to her tribunal every fact, every opinion.

I hold it that a little rebellion, now and then, is a good thing, and as necessary in the political world as storms are in the physical. Unsuccessful rebellions, indeed, generally establish the encroachments on the rights of the people, which have produced them.
