There is a group of Christians who believe that God is miraculously transforming old fillings to gold. Put it in a search engine if you don’t believe me. There are supposedly other manifestations, but that is the one that sticks in my memory.

Now, personally, I’d like to see the incredulous look on the face of your average Sudanese believer if someone tried to explain this phenomonon.

PDI is a semi/charismatic, Reformed doctrine “non-denomination” denomination that I used to attend. I think they’ve changed their name. It’s a home-schooling, child bearing, early thirties kind of group that I was completely out of place in. I think you can also still find them under PDI church on Google.
