I have heard many sermons on tithes and offerings over the years. There is another thread going on that asks if we should tithe. The obvious answer is yes. However, I have heard many different sermons with different standards for calculating the tithe. Here is some examples. The tithe should be based on (least to greatest) 10% after living expenses Net income Gross income Gross income + benefits Gross income + benefits + social security match Gross income + benefits + social security match + interest and dividends There are some other more detailed categories, but you get the idea. What should we base the tithe on? Is there Scriptural standards other than the opinion of the Pastor and the budget of the church? Is there any equivalent in the OT?
