Has the Sabbath been changed after Christ's resurrection? (Bible references)
The former treatise have I made, O Theophilus, of all that Jesus began both to do and teach. Acts 1:1 (Never a record of a change of the Sabbath!)
"And he [Paul] reasoned in the synagogue every sabbath, and persuaded the Jews and the Greeks." Acts 18:4
"For as the new heavens and the new earth, which I will make, shall remain before me, saith the Lord, so shall your seed and your name remain. And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the Lord." Isaiah 66:22, 23.
