Matthew 28 is written as an historical account of post resurrection events. It is not written to teach some profound message encoded within the text.
You do not understand the passage at all. It is a fact that the weekly Sabbath and the holy day of Abib 15 fell on the same day the year Yeshua died. Both days started at sundown and ended at sundown and both days require no work to be done (
Exodus 12:16). That year, the day Yeshua resurrected started when both the Sabbath and the first holy day of the Feast ended at sundown. I never said the Feast as a whole ended. Only the first day of the Feast (Abib 15) ended. Do you even know when the Feast is to be kept? "The first day of the week" and "the first of the week" mean the same exact thing. The word "day" is not needed, but was put there to clarify in English. As for "sabbaton" being translated "the first of the week", consider
1 Corinthians 16:2;
κατὰ
μίαν σαββάτων ἕκαστος ὑμῶν παρ᾿ ἑαυτῷ τιθέτω θησαυρίζων ὅ τι ἐὰν εὐοδῶται, ἵνα μὴ ὅταν ἔλθω τότε λογεῖαι γίνωνται.
Upon
the first of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.
The bold in Greek is the exact same phrase as in
Matthew 28:1. Does "sabbaton" refer to a new age of Sabbaths here? Of course not! It refers to Sunday just as it does in
Matthew 28:1.
Correct. It is not addressing work which is obviously forbidden. It is addressing the deeper spiritual ways to keep the 7th day Sabbath holy.
Paul and Barnabas went into a synagogue on the Sabbath. It was their custom to do so both before and after their conversion. They, at the request of the leader of the synagogue, were asked to speak. Paul began proclaiming the Gospel and was heard by both Jews and Gentiles. The Gentiles loved what they were hearing and desired to hear more the next Sabbath, not the "next day" (Sunday). If a new era of Sunday Sabbaths began in
Matthew 28:1, then Paul and Barnabas (yeshua's Apostles) did not know it. Otherwise they would have held a Sunday Sabbath service the next day. Instead, they waited an entire week to speak again. The next Sabbath (not the next day, Sunday) the whole city came to hear the words of life from the Word of God and from a retelling of the events that occurred in Jerusalem, primarily the death, burial and resurrection of Yeshua.
