No proof?
Did not Pope Francis put into his climate change encyclical that Sunday is needed to stop climate issues?
Are not Catholics calling for the same thing?
Was there not a conference just held in 2017 whose theme was "A Sabbath for the Earth and the Poor: The Challenge of Pope Francis"?
Did not Catholics in Poland NOT ONLY pray the rosary on their border, bu just decide to phase out Sunday shopping for the "Day of the Lord"?
Are not Sunday Laws being uplifted to fight against communism?
Is not Chick-Fil-A being promoted as Sabbath keepers in the public eye?
What exactly are you looking for? Governor Jerry Brown declaring that we need religion to fight climate change?
