"FIFTH REASON. Paul once broke bread upon the first day of the week at Troas. Hence this day was observed as the Christian Sabbath. Acts 20:7.
We answer that at one period the apostolic church at Jerusalem broke bread every day. Acts 2:42-46. If a single instance of breaking bread at Troas upon the first day of the week was quite sufficient to constitute it the Sabbath, would not the continued practice of the apostolic church at Jerusalem in breaking bread every day be amply sufficient to make every day a Sabbath?
And they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart,...Acts 2:46
But on what day of the week did this act of Paul’s occur? For, if it is of sufficient importance to make the day of its occurrence the future Sabbath of the church, the day is worth determining. The act of breaking bread was after midnight; for Paul preached to the disciples until midnight, then healed Eutychus, and after this attended to breaking bread. Acts 20:7-11. If, as time is reckoned at the present day, the first day of the week terminated at midnight, then Paul’s act of breaking bread was performed upon the second day of the week, or Monday, which should henceforth be regarded as the Christian Sabbath, if breaking bread on a day makes it a Sabbath.
But, if the Bible method of commencing the day, viz., from sunset, was followed, it would appear that the disciples came together at the close of the Sabbath for an evening meeting, as the apostle was to depart in the morning. If it was not an evening meeting, why did they have many lights there? Paul
preached unto them until midnight, and then broke bread with the disciples early in the morning of the first day of the week. Did this act constitute that day the Sabbath? If so, then why did Paul, as soon as it was light, start on his long journey to Jerusalem? If Paul believed that Sunday was the Christian Sabbath, why did he thus openly violate it? If he did not believe it had become the Sabbath, why should you? And why do you grasp, as evidence that the Sabbath has been changed, a single instance in which an evening meeting was held on Sunday, while you overlook the fact that it was the custom of this same apostle to preach every Sabbath, not only to the Jews, but also to the Gentiles? Acts 13:14,42,44; 16:13; 17:2; 18:4.
Paul broke bread on the first day of the week, and then immediately started on his long journey to Jerusalem. So that this, the strongest argument for the first day of the week, furnishes direct proof that Sunday is not the Sabbath."
