It is my understanding that Satanists believe Jesus was born on September 11th.
Satanists caused the World Trade Center catastrophe on September 11 so we would mourn on Christ's birthday instead of celebrating. They made the United States emergency call number 911, as if to mock us by calling our savior for help.
In a 13 Month Calendar, September is the 7th month, and the Gregorian calendar has July as the 7th month.
Christmas in July is mocking Jesus' birthday. The 7-11 convenience store is mocking Jesus as a convenience.
There is no more proof that Jesus was born on December 25 than September 11, so what does it matter? God knows what is in our hearts and I seriously doubt that Christians are worshipping Moleck on December 25th.
We should celebrate Jesus every day of the year and if we gather with family and friends on December 25th, I believe God will be there with us, just as He always is!
So, my point is, who cares what Satanists believe, what do you believe?
