You cannot save a pew since it has no soul.
Comedian Emo Philips:
“Once I was sitting at the Tivoli and this guy says, `Excuse me, is this seat saved?` I said, `Well if Thomas Aquinas reasoned that animals have no souls, how can an inanimate object like a chair achieve salvation?”
(Perhaps if it was done by proxy...since the proxy "stand-ins" have a soul...but this would need to come from the top Mormon "prophet," who dictates all doctrinal issues for the entire Planet Earth...say Mormon leaders...repeatedly so)
