Can any intelligent and candid reader of the inspired records fail to understand the narrative of Paul’s missionary work? He was sent forth “to turn sinners from darkness to light.” As he himself states at Antioch, addressing the Jews: “It was necessary that the word of God should first have been spoken to you.” His “heart’s desire and prayer to God for Israel was that they might be saved.” Accordingly, wherever he went, he was found going to them on the seventh day in _their_ places of worship, not in Christian houses of prayer; meeting with them in _their_ assemblies, not in assemblies of professed followers of Christ. Just as a Christian missionary, in modern times, going to a heathen land, would avail himself, if possible, of the customary assemblies of the residents, whatever day they might keep holy, so Paul and his fellow-missionaries availed themselves of the seventh-day assemblies of the Jews, that from among them, as well as from among the Gentiles, they might gather out an _ecclesia_—a body of followers of the Lord Jesus, in whom Jew and Gentile should be one. The question, therefore, still remains to be answered: Which day of the week did the church at Jerusalem, existing at the time of Christ’s ascension, which day did the apostles in their relations with this church, which day did the churches, organized and established by the apostles, and under their example and divine authority, observe as a holy day, a Sabbath to the Lord? In all the references to the seventh day, or Jewish Sabbath, there is not, as we have seen, a particle of evidence that that day was thus observed.
