“The opposite of faith is not doubt, it’s certainty.”

“I have a lot of faith. But I am also afraid a lot, and have no real certainty about anything. I remembered something Father Tom had told me--that the opposite of faith is not doubt, but certainty. Certainty is missing the point entirely. Faith includes noticing the mess, the emptiness and discomfort, and letting it be there until some light returns.”

“Take faith, for example. For many people in our world, the opposite of faith is doubt. The goal, then, within this understanding, is to eliminate doubt. But faith and doubt aren't opposites. Doubt is often a sign that your faith has a pulse, that it's alive and well and exploring and searching. Faith and doubt aren't opposites, they are, it turns out, excellent dance partners.”

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

“All great discoveries...are products as much of doubt as of certainty, and the two in opposition clear the air for marvelous accidents.”

“What if the choice isn’t between certainties, between this faith and that, but between faith and doubt? Between renouncing the mystery and embracing it?”
