How many people will support such tax exempt church without tax deductibility of their contributions?
Sadly many will refuse to give if they themselves do not receive a tax write off. In all my years of giving, I have never once taken advantage of my right to a tax exemption for the money I gave back to God.
I am not criticizing others for doing so, but as for me and my house I will put my faith in the Lord's promise, not Caesars benevolence.
Whether or not individual donations are tax deductible is one thing, but once the government at any level starts to tax churches there won't be any more freedom of religion because there will be tax penalties for those who don't agree with the State Religion of Secular Humanism and all it's wonderful goals like queers marrying one another and so on.
