Providing tax exempt status to only churches you have "proven" to be churches should be seen as legislating religion. The only ACTUAL fair way to handle it is allow any organization to vie for charity style tax exempt status, with a high bar of charity required to succeed, and churches are otherwise no more an organization than your company's softball team.

Alternatively, nobody gets ANY tax exempt status, and we should stop using tax deductions as subsidies, because they are only really available to those with ample money to play with and can afford more experienced tax professionals
