... if this is so, why would you arbitrarily end the reference at verse 22?
If Sabbath ended at the cross, then Joseph of Arimathaea and the Galilean women must have sinned when they observed the Sabbath day after the death of Messiah on the cross: "And they returned, and prepared spices and ointments; and rested the sabbath day according to the commandment." Lk 23:56, Mk 16:1.
So must have the early believers in Asia Minor also sinned, when they observed Sabbath: "the Sabbath or Saturday (for so the word sabbatum is constantly used in the writings of the fathers, when speaking of it as it relates to Christians) was held by them in great veneration, and especially in the Eastern parts [Asia Minor] honoured with all the public solemnities of religion. For which we are to know, that the gospel in those parts mainly prevailing amongst the Jews, they being generally the first converts to the Christian faith, they still retained a mighty reverence for the Mosaic institutions, and especially for the sabbath, as that which had been appointed by God himself, (as the memorial of his rest from the week of creation,) settled by their great master Moses, and celebrated by their ancestors for so many ages, as the solemn day of their public worship, and were therefore very loth that it should be wholly antiquated and laid aside. For this reason it seemed good to the prudence of those times, (as in others of the Jewish rites, so in this,) to indulge the humour of that people, and to keep the sabbath as a day for religious offices. Hence they usually had most parts of the divine service performed upon that day; they met together for public prayers, for reading the scriptures, celebration of the sacraments, and such like duties. This is plain, not only from some passages in Ignatius and Clemens's Constitutions, but from writers of more unquestionable credit and authority. Athanasius, bishop of Alexandria, tells us, that they assembled on Saturdays, not that they were infected with Judaism, but only to worship Jesus Christ, the Lord of the sabbath" (William Cave, Primitive Christianity)
The Apostle John was the elder overseeing the Asia Minor churches at the time. John's prominent disciple, Polycarp, observed Sabbath, and protested Rome's substitution of Sunday for Sabbath.
