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.
Your opinion of and subsequent attack of Adventism and it’s millions of believers is duly noted. To ease your concern/fear of ‘Sabbath-keeping’ I’ll inform the Adventist powers-that-be that their historical support and endorsement of civil blue laws must be disavowed and.....oh,wait. Never-mind. Also please advise/warn Teddy and Heidi that soliciting and accepting ‘donations’ from Adventists and their institutions could prove disastrous to their spiritual well-being. The apostle Paul would NOT be pleased.....you have a blessed day.
