"The greatness of the Christian saint lies in their readiness to be questioned, judged, stripped naked and left speechless by that which lies at the center of their faith."
– Rowan Williams, The Wound of Knowledge, 10.
In other words, saints aren’t those who have more intelligence than others, or those who have more knowledge than others, or those who have scrupulous morals. It is those who simply submit to the fire of God’s chaotic unmaking that He might re-make them as a "new creation."
This is usually an unpleasant, humiliating and confusing experience, so it takes some trust that ultimately God is working to bring transfiguration from glory to glory.
