Tell that to Paul, as he stated about meeting the first day of the week, and Peter and James who never told the gentiles to obey it in their letter after the first Council in Jerusalem.
Yes. Romans 14:5.
“Tell that to Paul, as he stated about meeting the first day of the week”
Paul met congregations at different times for different reasons, but it did not change the Sabbath day.
“and Peter and James who never told the gentiles to obey it in their letter after the first Council in Jerusalem.”
They made no reference to it because it was not a matter they were talking about, and they certainly were not implying there was NOTHING else one need do.
Acts 18:4 And he (Paul) reasoned in the synagogue every Sabbath, and persuaded the Jews and the Greeks (Gentiles).
