Karen Armstrong speaks about her progression from a disillusioned and damaged young nun into, in her words, a “freelance monotheist.” She’s a formidable thinker and scholar, but as a theologian she calls herself an amateur — noting that the Latin root of the word “amateur” means a love of one’s subject.
