It's unfair to TV ministers like Mac Hammond and Kenneth Copeland to call Popoff a televangelist. They give the impression of having real faith. They truly preach.
Popoff does infomercials for worthless products aimed at the desperate and gullible end of the prosperity gospel market. Like a celebrity look-alike, he makes money by resembling people who at least worked to become caricatures of insincerity.
Popoff was a "successful" faith healer before he was exposed for receiving divine revelations about audience members over a wire. After declaring bankruptcy and disappearing for a while, he's back.
My son called me after seeing a late night pitch for Miracle Manna Cakes, cooked in an oven in the Holy Land using the Old Testament recipe. "You'll love this," he said.
That's just one offer in a steady stream of "free" trash peddled to keep the revenue flowing — deli salt packets (Dead Sea Salt), tap water (Miracle Spring Water) and Golden Miracle Bands made of paper. Perform some ritual with the item, then send Popoff a payment so you receive further instructions on how to effect a "divine transfer" into your bank account.
Popoff's careful to say that the water or cracker won't cause the promised wealth to appear. Your submission to the will of God, signified by sending Popoff money, triggers your prosperity. Otherwise, his instructions might be mistaken for mail fraud.
If this hasn't exceeded your daily does of snake oil, there's more on Popoff here.
Cure trinkets are also popular fund-raising devices, but healing is more useful in televised theatrics that inspire the larger market. Not everybody has the cancer or the lumbago, but everybody wants the manna.
