Was it possible that the church needed Dunn’s building? That may justify it somewhat, but It sounds like a conflict of interest, anyway, if the church is buying property from high ranking GA’s. They are really strict about us average rank and file members carrying on business activities in the church (I experienced that when I was a young, naive 25 year old and made up a missionary-oriented t-shirt I sold to missionaries — I got my hand slapped really quick).
I think they should be just as militant with GA’s. The church has a reputation for being hard to do business with anyway, I’ve heard , from various construction people.
