How is there monotheism with it?
It’s incrementalism. One piece at a time, liberals alter the landscape. One less devil here, one less “anti gay slur” rewritten in a more ‘acceptable/less offensive way, there, repeated over and over, and we all wake up one day to entire faiths embracing gay marriage, Popes having Muslims over to consecrate the Vatican for Allah and the rest.
I fully expect, in my remaining life, to see several ‘churches’ come out and tell us that “Jesus” was simply a metaphor” and Heaven is what we make it right here on earth.
