Clearly not Christian behavior and I would say those that defend it should examine their relationship with our LORD and SAVIOUR.
What would you have the Church do?
These people were theologically and Scripturally wrong; they are wrong today. Should we shrug our spiritual shoulders and wave as the heretics and apostates merrily board the hellbound express?
What should the Church of Jesus Christ do when the arrogance and hubris and pride of mankind leads so many of them into Satanic embrace?
