Rohr on crisis of faith
When we grow, our image of God and our self-image normally move forward on parallel tracks. And if one of the two breaks down, the other has to come apart too. We stick to both of them, and both stick together. Every crisis of faith implies that one or the other side is cracking up. If you really grow in faith, then in my opinion this process ought to take place at least every two or three years. This is the darkness of faith: when you've had to drop the old for a time but haven't yet found the new.
