I hope the predictions of this piece is accurate. But I doubt it.
A quick way to restart the exodus from the pews is to make the church even more overtly partisan, rather than spiritual.
When was an evangelical in the 90’s and the 00’s the churches my family attended were frequently GOP rallies with a veneer of Jesus over top. This change in IRS policy that seems to have never ever been enforced to start with will make no difference. The gloom and doom of this piece that suggests that political entities will start dumping money into churches to stump for their candidates - I don’t think that’s going to happen, since the churches that would be game - are already doing it.
It was enforced once in 94. That’s it.
The separation of church and state has been thoroughly violated at this point.
