So gold and silver are evil, demon possessed and if we own anything shiny like a gold wedding ring we should throw it out? How about the beautiful silver tray that was lovingly handed down for generations? The diamond necklace that was given to you by an adoring husband?
And crystals? From wikipedia: "Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice."
So I guess we should get rid of salt, snowflakes, most metals, rocks, ceramics, and ice and of course, diamonds.
As for demons, just call on Jesus. I have experienced that Jesus can stop all demons and my guardian angel is also no slouch.
Interesting how this guy (mis)uses the Bible to solidify his hypothesis.
