An ex-Adventist named Kerry Wynne has paper on internet. He says that Gentiles abandoned the 7th day Sabbath (i.e. keeping the Sabbath and going to church on Sabbath) by 140 A.D. I guess God ... wanted that to happen even though I cannot prove anything from the bible
Acts 15 records that Jerusalem church told Gentile church in Antioch not to worry about Judaizers or about circumcision but just focus on being sexually pure and don’t eat foods dedicated to idols or with blood in it. No word about Sabbath-keeping. Holy Spirit approved
