'Doubt in this way becomes an antidote against believing rumor. Doubt keeps us from falling prey to authoritarians that hide behind the church. Doubt keeps us from following a person rather than following Christ. Doubt encourages us to study, no matter where our starting point is. Doubt encourages us to engage in contemplative prayer – that form of prayer where we stop submitting our wish list and simply listen. Doubt prepares us to grow spiritually from drinking milk to solid spiritual food.

And hopefully doubt saves us from being crushed when the people we’ve looked up to let us down, or are no longer here.'
