Our congregation has had the same discussions, in the form of talks, for the last 4 weeks in a row. Yes, every meeting either mentions money, or has a blatant talk on the need to contribute more. Local needs talk? Yep, contribute more, Mother needs your money.
2 full weeks, both Sunday morning and Tuesday nights, were spent passing out pink "contribution" slips, to get "a feel" for what we were willing to contribute every month. Then 2 more full weeks of "reminders" to get your slips in.
Reasons were the same as mentioned by the OP, James. Our contribution amount that was used to set the monthly amount last year... has slowly been draining the congregation funds down to almost nothing.
Got to reaffirm those tithes!
