Jesus founded a sabbath keeping church. Peter, Paul John and every other Christian in the bible belonged to a sabbath keeping church. Why don't you do what Jesus and the apostles did?
Do you believe Christians must keep the law, including resting on the 7th day Sabbath?
Christians can and do sin. If we realize we're sinning it's on us to repent and stop sinning.
A sabbath keeping church?
Really?
Show me one verse in the NT that after Pentecost, any Christian is instructed to keep the Sabbath or is recorded as keeping the Sabbath?
History shows Christians worshippers on the first day of the week from the beginning, the Lord’s Day. Anyone following the Apostolic Tradition as the Scriptures command us would know this.
Those who disobey the Scriptures and do not follow the Apostolic Tradition, are lost in following the tradition of men.
