When I was a kid, I went to a Franciscan church and school. St. Francis of Assisi was this awesome guy who did Christianity a solid.
Now, at age 32, after reading Thomas of Celano, I am now 99% positive that Francis went certifiably batshit. Here's somebody who you would think that had an actual clue of what being Christian was, sorta, and his fall into becoming "the knight of the LORD" is a full on nervous breakdown. Unlike Margery Kempe, who just did it for attention, I think poor Francis (who maintained epic anti-Semitic views from his rich brat days) went full potato.
Holy hell. This stuff is GREAT, if not sad. Really.
