Saint Matthew's Churches possible rip-off Tulsa Oklahoma

I received the letter from Saint Matthew's Prayer Family, saying they had prayed for the letter before mailing and would pray for me and send me a "prosperity faily cross" and a book called'The Seed Principle".
I decicided to check them out on the internet before I even considered replying. I'm glad I did. I hope I'm not already on their permanent mailing list. The other report suggested sending back everything in the pre-paid envelope. They must be getting a lot of it back because my letter did not include an envelope, just a pre-paid post card.
Thanks
