The fact that this question is asked at all, much less in christian circles is evidence of the deterioration of our civilization. For almost all of the existance of our country, Americans have considered it a āno brainerā to exempt religious organizations for providing the moral character formation, charity outreach, hospitals, soup kitchens, homeless shelters, adoption services that the government would be hard pressed to do on 5 times the amount that could be squeezed out of them in the form of taxes.
Case in point, Catholic Charities of IL adoption services was recently forced out of providing State adoption administration because they refuse to place kids in same sex couple homes. The state previously contracted with Catholic Charities because they could do these services for less than any other agency and for less than 1/5 of the per child cost of the in-house state social service agencies. No matter, they refused to bow down to the Emperor, so must be thrown to the lions.
The fact is that the government could never afford to do what the churches do for society. If you tax them (even just real estate taxes), most will fold or go underground into house churches, the revenue lost anyways and the taxpayer will be the chumps paying for the social services needed until the Barbarians tear down the gates (closer than most think).
