Hi,
I've always thought burying a statue of a saint too superstitious, but I did make a novena (nine days of special prayers) asking for St. Joseph's intercession in selling our home. After ten months on the market, with two different realtors, it sold quickly after I finished the novena. I just shared it with a member of our parish whose home had been listed for months, and --- his home sold the week after finishing it.
