Katharina Zell quotes:

[On refusing to be silenced:] I do not pretend to be John the Baptist rebuking the Pharisees. I do not claim to be Nathan upbraiding David. I aspire only to be Balaam's ass, castigating his master.

Governments ... should not force and govern belief, which is a matter for the heart and conscience not for temporal authorities.

Faith is not faith which is not tried.
