1- In Antioch, Paul “went into the synagogue on the Sabbath day” (Acts 13:14). Jews and Gentile converts to Judaism worshiped there (verses 16 and 26). After preaching the gospel, “the Gentiles besought that these words might be preached to them the next Sabbath” (Verse 42). Then, “the next Sabbath day came almost the whole city together to hear the word of God” (Verse 44).
3- In Thessalonica, Paul preached on the Sabbath and for “three Sabbath days reasoned with them out of the scriptures, opening and alleging, that Christ must needs have suffered, and risen again from the dead” (Acts 17:1-3).
5- In Ephesus, Paul, “went into the synagogue, and spoke boldly for the space of three months, disputing and persuading the things concerning the kingdom of God” (Acts 19:8). This was obviously on the Sabbath days, as in Antioch, Corinth and Thessalonica.
6- Paul was NEVER accused of Sabbath-breaking by Jews. Eventually, Paul was arrested in the Temple in Jerusalem (Acts 21). At his trial before the Sanhedrin, even the Pharisees admitted, “we find no evil in this man” (Acts 23:9). Before Felix, Paul testified, “so worship I the God of my fathers, believing all things which are written in the law and in the prophets” (Acts 24:14). Before Festus he declared, “to the Jews have I done no wrong” (Acts 25:10). Before Agrippa, “I continue to this day … saying none other things than those which the prophets and Moses did say should come” (Acts 26:22). Finally, Paul spoke to the Jews in Rome, “persuading them concerning Jesus, both out of the law of Moses, and out of the prophets, from morning till evening” (Acts 28:23). During all of his trials, the Jews never once accused Paul of breaking the Sabbath because he never did!
7- A Jerusalem council (Acts 15) led by the apostles was organized to discuss “this question … this matter” of “circumcision” and “the law of Moses” (Acts 15:1, 2, 5). The Sabbath itself was not debated or even discussed. The Church decided that the Gentiles were “saved … through the grace of the Lord Jesus Christ” (verse 11) and thus they did not need to be circumcised. At this early date in Church history, believing Gentiles were still worshiping with the Jews in their synagogues “every Sabbath day” (Verse 21). Thus, verse 21 proves that the “Sabbath day” was not changed to Sunday by the Jerusalem Council.
