"Have before thine eyes the fear of God, and always remember the ten commandments of God,--to love the one and only Lord God with all thy strength; to give no heed to idols, or any other beings, as being lifeless gods, or irrational beings or dæmons. Consider the manifold workmanship of God, which received its beginning through Christ. Thou shalt observe the Sabbath, on account of Him who ceased from his work of creation, but ceased not from his work of providence: it is a rest for meditation of the law, not for idleness of the hands." Book ii., sect. 4, par. 36. This is sound Sabbatarian doctrine. But apostasy had begun its work in the establishment of the so-called Lord's day, which was destined in time to drive out the Sabbath. The next mention of the Sabbath also introduces the festival called Lord's day, but the reader will remember that this was written, not in the first century, but the third:-- "Let your judicatures be held on the second day of the week, that if any controversy arise about your sentence, having an interval till the Sabbath, you may be able to set the controversy right, and to reduce those to peace who have the contests one with another against the Lord's day." Book ii., sect. 6, par. 47. By the term Lord's day the first day of the week is here intended. But the writer does not call the first day the Sabbath, that term being applied to the seventh day. In section 7, paragraph 59, Christians are commanded to assemble for worship "every day, morning and evening, singing psalms and praying in the Lord's house: in the morning saying the sixty-second psalm, and in the evening the hundred and fortieth, but principally on the Sabbath day. And on the day of our Lord's resurrection, which is the Lord's day, meet more diligently, sending praise to God that made the universe by Jesus and sent him to us." "Otherwise what apology will he make to God who does not assemble on that day to hear the saving word concerning the resurrection, on which we pray thrice standing, in memory of him who arose in three days, in which is performed the reading of the prophets, the preaching of the gospel, the oblation of the sacrifice, the gift of the holy food." The writer of these "Constitutions" this time gives the first day great prominence, though still honoring the Sabbath, and by no means giving that title to Sunday. But in book v., section 2, paragraph 10, we have a singular testimony to the manner in which Sunday was spent. Thus the writer says:-- "Now we exhort you, brethren and fellow-servants, to avoid vain talk and obscene discourses, and jestings, drunkenness, lasciviousness, luxury, unbounded passions, with foolish discourses, since we do not permit you so much as on the Lord's days, which are days of joy, to speak or act anything unseemly."
