Mandatory Tithing? Never say never! Imagine if you will, going back in time 30 years to 1986 and telling your former JW self that in 30 years not only would the New System NOT yet be here, but that the Book Study in homes would be deleted, Field Service would consist of standing by carts, cartoons would used to "teach" children, videos would be shown at conventions, and ATM's would be located to donate quickly. Oh! And that you'd be all lovey-dovey with the GB Members, as they parade around televangelist style!!
Now ask yourself, what would your 30-years younger self had said to all of THAT? So "mandatory tithing", doesn't sound so far-fetched now, does it?
