(why) do you tithe?

[libalchris]

With my former religion tithe was up there with the ten commandments. 10% of all income if you're a good christian (tithing was tax deductible for the giver.) Speakers would sometimes mention if the issue of tithe came up, that you should always pay your tithe to the church even if you disagree with what the church leaders are doing with the money because when you give your money to the church God is in control with it an he knows what he's doing. Pretty ridiculous. Most people just wrote out a check once a week for 10% of their income plus some extra offerings.
