This from an organization which teaches that if you do something as innocuous as lighting candles and putting them on a birthday cake you are engaging in false worship because of what such activities meant to pagans in ancient times (Reasoning book, p. 69).
But selling a building you built and dedicated to worship and service of Jehovah for use in worship by a religious organization you condemn as pagan and satanic? Not a problem!
"There
does not appear to be any direct Scriptural objection to doing so. It is not a
matter of cooperating in a religious way with representatives of false
religion, but is simply a business transaction. It is a one-time real estate
deal."
Kind of like the Watchtower becoming a UN NGO so they can get a library card, I guess.
What's the big deal?
