Then we go "underground".
Churches should be preparing for that now - they must be able to exist without their building(s).
Churches should be more than willing to lose their “tax-exempt status” in order to stand by the Truth.
Some notes, though:
No church has EVER lost this status.
Even if your pastor “crosses the line” from the pulpit, the church is only responsible for taxes prorated for the relative amount of time spent on the topic compared to the whole amount of “church time” spent during the whole year.
This could be fought off for a long time, unless the AC and the left in general wants to just “cry havoc”.
