A couple of questions for those who believe that tithing means 10% of your income (not being snarky - actually curious).
1) Is it gross or net income?
2) If part of (or all of) one's "income" is welfare, does one still tithe?
3) Do you claim it as a deduction on your income tax?
1) The Bible does not say you need to give 10% to your Church. It is a tithe to God. If you have 100 oxen, then you give 10. That at first would seem like gross, but when that was written was there a state income tax. Later the Romans had a tax but I am not sure how it was assessed. Then you could say net, since that is really what you get.
For me it is gross, but part of my income taxes are included. I send money to the federal, state and local government that is used to feed, clothe, house etc others and that is doing God's work. Some goes to my Church to run the building, pay the Priest, help out the less fortunate and many others. The third part is where I help others. Some via charities and others directly. If I buy the neighbor food for the month because they are hungry. I don't have to give it to a church so they an then give it to the neighbor.
2) It should include all sources of money. So yes, welfare should be included as should SS disability payments, SS payments, interest income, dividends and the like.
3) We claim the ones we can legally and not the others. You cannot take a tax deductions for a contribution made to a specific person. Since we do more of our after tax money in the later, more than half does not get deducted.

If you give your Church 10% after taxes and then do not save for your old age so the government has to support you, did you really tithe the Church?
What is you only gave 5% and saved 5% but supported yourself in retirement, are you a lesser christian?
IMHO the answer to both is NO.
It is possible that that 5% the first person gave to the church was what the person then took from the government, so the really gave the same as the second.
