I'd like to see ANY 'scriptures' from the MORMON pantheon that says that PROXY WORK by men is ACCEPTABLE!
IIRC Acts 29:12 talks of Paul (a mortal man) curing disease through the proxy of a handkerchief when he couldn't go himself.
Again IIRC that's right before the sons of sceva, a great example on the need for actual authority.
So, is Paul doing proxy work good enough for You? If not you'll have to wait till I get to a computer.
