The Society has always been against tithing..........a stand they took from early times and which hasn't changed...........
Do you think they now wish they had incorporated tithing, with all the money they seem to be requiring. (Ex.- every year the donation options mentioned prominently in the Watchtower)
Tithing has obviously worked well for the Mormons, what would happen if they now decided to include this "principle" today?
The donations I give are almost nill.......just a token.
