Paul Tillich

"Sometimes I think it is my mission to bring faith to the faithless, and doubt to the faithful."

"I hope for the day when everyone can speak again of God without embarrassment."

"Doubt isn't the opposite of faith; it is an element of faith."

"Astonishment is the root of philosophy."

"Doubt isn't the opposite of faith; it is an element of faith."

"Doubt isn't the opposite of faith; it is an element of faith."

"The first duty of love is to listen."
