Religious conversions later in life are generally greeted as evidence that something terrible must have happened to the converter. The Onion published a satire in 2016, ridiculing Paul D'Amatol, who took up a life of Christian piety in late middle age. It must be 'drugs or maybe he killed someone in a car accident. Something super messed up.'
No room in satire for something good as the cause. Interestingly, it's not Protestant evangelical born-again-ism but the Catholic bells-and-smells and Islamic mysticism that attract those interested in spiritual growth as they approach the end, despite (because of?) Rome's/ Islam's hard teachings on divorce, homosexuality, the ordination of women. Catholics and Muslims take their religion seriously.
From fire by water: My journey to the Catholic faith, a memoir by Iranian American Sohrab Ahmari, is provocative, to say the least.
