you need to take off the Ellen White glasses when reading Scripture.
the Church keeps the Apostolic Tradition as commanded by Paul, not the “tradition of men” condemned by Jesus.
Acts 17:2 does not say Paul kept the Sabbath.
After Pentecost, the NT does not record any Apostle keeping the Sabbath.
the “Lord’s Day” is the first day of the week, the day Jesus rose from the dead.
Jesus is our Sabbath, we rest in Him.
please “bombard” me with NT verses that tell us we need to keep the seventh day sabbath after Jesus went to the cross.
