It is a significant fact that the day of Pentecost, upon which day the apostles received their spiritual endowment by the outpouring of the Holy Ghost, "that year fell on the first day of the week." [A] "And when the day of Pentecost was fully come, they _were all with one accord in one place"_ (Acts ii:1). They received the outpouring of the Holy Ghost, and publicly preached the gospel and administered baptism. This assembling together on the first day of the week was doubtless in continuation of that new order of things with respect to the Sabbath which Jesus had ordained. [Footnote A: See Smith's Dictionary of the Bible, Hackett & Abbot's edition, Vol. II: Art. Lord's Day, p. 1677. Also Bramhall's works, Vol. V: p. 51, Oxford Ed., Discourse on the Sabbath and Lord's Day.] Many years after Pentecost, in giving the account of Paul's journey from Philippi to Troas, the writer of the Acts of the Apostles says that the journey was accomplished in five days; and at Troas the apostolic party abode seven days; _"and upon the first day of the week,_ when the disciples came together to break bread, Paul preached unto them, ready to depart on the morrow; and continued his speech until midnight" (Acts xx:4-7). Again: Paul sends the following instructions to the Saints at Corinth--and it is to be seen from the passage itself that he had given the same instructions to the churches of Galatia: "Now, concerning the collection for the Saints, as I have given order to the churches of Galatia, even so do ye. _Upon the first day of the week_ let every one of you lay by him in store, as God has prospered him, that there be no gatherings [i. e., collections] when I come" (1 Cor. xvi:1,2). These passages prove very clearly that the custom of meeting together for acts of public worship and the preaching of the gospel was firmly established in apostolic times, and since that is the case it doubtless was ordered by Messiah's own appointment. Surely the apostles would not presume to establish such an order of things without divine sanction. Within the life time of the last of the apostles, too, this Christian Sabbath had received its name--"the Lord's Day." John's statement--"I was in the spirit on _the Lord's Day,_ and heard behind me a great voice," etc., can have reference to no other thing than the fact that on the first day of the week which had come to be known by them as "the Lord's Day," John was in the spirit. "The general consent, both of Christian antiquity and modern divines, has referred it to be the weekly festival of our Lord's resurrection, and identified it with 'the first day of the week,' on which he rose; with the patristical 'eighth day,' or day which is both the first and the eighth; in fact with the _'Solis Dies'_ or 'Sunday,' of every age of the church."[A] [Footnote A: Smith's Dictionary of the Bible, Vol. II; p. 1676.]
