Pieczenik and Firecracker!

You pose a great question, and I do not have an answer.
Most churches are not churches anymore. They have become 501.c3 charities. And a lot of what is being done under the name of Christianity is not following scripture.
And the Christian view is that all who sin can repent and accept Christ as their savior and wash away all their previous sins.
So Satanists are simply people whose souls the Christians are challenged to "save".
However, I want to point out there are some churches who are not part of the red door club (World Council of Churches) who are still following the scripture and whose pastors have not become part of the Clergy Response Team under FEMA. Those in the Clergy Response Team have agreed to persuade their 'flock' to obey the government and when the time is right, to give up their firearms and go to the FEMA camps. DISGUSTING!
I'm not a good one to ask, however, as I gave up regular church attendance years ago when the Organist (married) was humping the Choir Director. And one of the Deacons brought his girlfriend (not his wife) to our place to meet the family. Meanwhile, the goody goody's in the church seemed to want to nose into everyone's business. I had enough. Decided to spend my Sunday mornings differently.
