You have absolutely no idea what Dr. Carson was doing at a church on Sunday. You are assuming with your ‘What ifs’. For you to render judgement on his personal activities regarding his faith based on YOUR ‘suspicions’ and What if’s, tells me you definitely have an eye/log problem....like a modern day Pharisee. As for Adventists being in ‘darkness’, who are YOU to judge anyone’s spirituality?
If anyone teaches you need to keep the Sabbath after Jesus fulfilled the Mosaic law, they are teaching another Gospel per Paul.
Ellen G White was a false prophet and fooled many unfortunately.
