Astonishment is the root of philosophy. - Paul Tillich

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

"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."

"The first duty of love is to listen."

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