Come on, be serious, scroll up to my post near the top. "Sunday worshippers" is the name of their service too?
It gets better, look up why God's Commanded Sabbath, Saturday, was not adopted by Constantine's corruption of Christianity (nor later by Martin Luther, Calvin, the Reformation, and the rest of that Earth shaking bunk that changed nothing other than not recognizing the Papacy). Sunday mass really IS worship of the Sun God, Sol Invictus. Every bit as pagan as Easter (Ishtar), Christmas (Happy birthday Mithra!), and all the Holy Days never even hinted at in the Bible are.
