“And _he reasoned in the synagogue every Sabbath_, and persuaded the Jews and the Greeks.” Acts 18:4. 13. How long did he continue this work there? “And he continued there _a year and six months_, teaching the word of God among them.” Verse 11. NOTE.—Here, then, were seventy-eight Sabbaths on which Paul preached in one city. The record further says that he worked at his trade, and we may justly infer that Paul worked at tent-making just as many Sundays as he preached Sabbaths. If to these seventy-eight Sabbaths we add the three he spent at Thessalonica, the one at Philippi, and the two at Antioch, we have a record of eighty-four Sabbaths on which the apostle held religious services, while, so far as the record shows, he held only one meeting on the first day of the week, and that a night meeting, immediately following the Sabbath. See Acts 20. Evidently Sunday was not the Sabbath in Paul’s day. 14. On what day was John in the Spirit? “I was in the Spirit _on the Lord’s day_.” Rev. 1:10. 15. Who is Lord of the Sabbath? “_The Son of man is Lord also of the Sabbath._” Mark 2:28. 16. What, through the prophet Isaiah, does the Lord call the Sabbath? “If thou turn away thy foot from the Sabbath, from doing thy pleasure on _My holy day_.” Isa. 58:13. 17. Why does the Lord call the Sabbath His day? “For in six days the Lord made heaven and earth, the sea, and all that in them is, and _rested the seventh day_: wherefore the Lord _blessed_ the Sabbath day, and _hallowed_ it.” Ex. 20:11. 18. Through whom did God create the world? “God ... hath in these last days spoken unto us by _His Son, ... by whom also He made the worlds_.” Heb. 1:1, 2. NOTES.—From beginning to end, the Bible recognizes but one weekly Sabbath,—the day upon which God rested in the beginning; which was made known to Israel at Sinai (Neh. 9:13, 14); was observed by Christ and His apostles; and is to be kept by the redeemed in the world to come. Isa. 66:22, 23. The terms Sabbath, Sabbaths, and Sabbath days occur sixty times in the New Testament, and in every case but one refer to the seventh day. In Col. 2:16, 17, reference is made to the annual sabbaths connected with the three annual feasts observed by Israel before the first advent of Christ. The first day of the week is mentioned but eight times in the New Testament, six of which are found in the four Gospels, and refer to the day on which Christ arose from the dead. See Matt. 28:1; Mark 16:2, 9; Luke 24:1; John 20:1, 19. The other two (Acts 20:7; 1 Cor. 16:2) refer to the only religious meeting held on the first day of the week after the ascension, in apostolic times, recorded in the New Testament, and to a systematic accounting and laying by in store at home on that day for the poor saints in Judea and Jerusalem.
