I received a genuine paper faith handkerchief in the mail from a church, because "someone connected to [my] home needs God's help and blessings." I was supposed to print my name and my "most pressing problem, by faith" on the handkerchief, and place it by the bed while I slept. Then the next day I was supposed to mail it back to them. And lest you doubt, these handkerchiefs apparently have amazing powers! According to the letter, people have had fathers and husbands stop drinking, had a son get out of jail (I'm assuming legally, but they weren't clear on this), had their home fixed up, gotten a check for $3,500, gotten big financial blessings, gotten $5,000, and gotten a check for $2,500. (There seems to be kind of an interesting pattern to a lot of these.)
I figured my most pressing problem at the moment was the rotten sinus problems I've been having for weeks, so I put that down and went to sleep. (I always do everything strange churches tell me to do in the mail.) Of course, having a handkerchief handy right by the bed when you wake up in the middle of the night with sinus problems leads to only one conclusion, and now I'm not sure if they really want the handkerchief back....
(1) Oh come on, now, you didn't really think I was serious, did you? The "handkerchief" is a printed 8x10 piece of paper. Like I really need paper cuts on my nose in addition to bad sinuses. Or that I'd actually listen to a church, for that matter.
(2) I remember these used to go out as "prayer rugs", I think. They've apparently now found a bible passage that sort of ties in with what they're doing, so they call them "faith handkerchiefs" now. (Acts 19:11-12, if you're interested. It looks to me to be a "We must hold high his holy gourd!" type of interpretation if I ever saw one.)
