Well I don't know who Mike Warnke is but I guess it doesn't matter.
Back in the 70's and 80's, Mike Warnke was a guy who wrote a book called "The Satan Seller", in which he claimed to have been a Satanic high priest, joined the Marines, went to Vietnam, became a war hero, and got saved.
The only problem is that all of it was a lie. He was never a Satanist. He was never a war hero. He never saw combat in Vietnam. He was a Marine but the closest he got to combat was giving Marines shots for VD at Subic Bay.
He parlayed the success of the book into an act where he would go around the country doing Bill Cosby's comedy routine (literally word for word...how he managed to avoid being sued, I'll never know) and talking about Satanism.
Then, one day in the early 90's, Cornerstone Magazine did a long expose, in which they interview people from the book, Warnke's family, and exmined Marine Corps records and exposed him as a fraud.
The story is still available
here.
As a result, he was forced to stop his activities and disband his "ministry". He was hit with several federal felony charges, including tax evasion and wire fraud.
Finally, his wife divorced him, claiming spousal abuse.
He's back now, but not very popular. He was, at one time, the biggest star in Christian entertainment, but now, most people have never heard of him.
You might want to take a minute to clarify your post. It seems that, first you're saying that it's a good idea to rub oil on your doorposts and then you're saying it's not.
I think I understand what you're saying, but it might confuse some.
