It’s also the cornerstone of ancient paganism. Someone invented God/s along the way.
Loving/worshipping the planet we live own isn’t such a bad thing. Using it to push a socialist agenda is.
For Bible believers, its all a heresy. Earth worship is blasphemy since we are to worship God, not one of his many creations.
That makes as much sense as the pagan ancient Egyptians who worshiped the sun.
