Are you saying that the L.D.S. Bishop who wrote this article for LDS.org is a slanderer and a liar?
Since you seem to feel something is in that article that I haven’t found, would you mind pointing it out?
Logic would indicate, that a Bishop with rudimentary math skills is going to be able to easily guess a range of income of anyone who is honestly declaring themselves a full tithe payer.
That said, there is no asking or telling of income levels, just as JDW11235 has stated.
What business is it of ANY church if you are "declaring yourself a FULL TITHEPAYER??? I know of no Christian denomination that has that as doctrine.
