Imperfect Saints

Colin Dickey contemplates them in Afterlives of Saints. From Lindsay Reckson's review:

These are not the standard, well-behaved saints, the Johns, Jameses, and Josephs. They are instead, as Dickey notes, the miscreants: "saints who murder, saints who [gouge] out their own eyes and hold them out for inspection, saints who minister to the petty and the bizarre and the maligned." Dickey’s saints are petulant in their pursuit of spiritual perfection. They steal away, sequester themselves, or expose their suffering for all to see. They are excessive, indecorous, mad, and mostly unable to live in the world. They are, for better or worse, a lot like us.
