On page 38, a commandment from the apostles is given: "On the first [day] of the week, let there be service, and the reading of the holy Scriptures, and the oblation," because Christ arose on that day, was born on that day, ascended on that day, and will come again on that day. But here is one truth, one falsehood, and two mere assertions. The apostles are represented, on page 39, as commanding a fast of forty days, and they add: "Then celebrate the day of the passion [Friday], and the day of the resurrection," Sunday. But this would be only an annual celebration of these days.

And on pages 38 and 39 they are also represented as commanding service to be held on the fourth and sixth days of the week. The Sabbath is not mentioned in these "Documents," which were written about the commencement of the fourth century, when, in many parts of the world, that day had ceased to be hallowed.

Justin's "Apology" was written at Rome about the year 140. His "Dialogue with Trypho the Jew" was written some years later. In searching his works, we shall see how much greater progress apostasy had made at Rome than in the countries where those lived whose writings we have been examining. And yet nearly all these writings were composed at least a century later than those of Justin, though we have quoted them before quoting his, because of their asserted apostolic origin, or of their asserted origin within a few years of the times of the apostles.

It does not appear that Justin, and those at Rome who held with him in doctrine, paid the slightest regard to the ancient Sabbath. He speaks of it as abolished, and treats it with contempt. Unlike some whose writings have been examined, he denies that it originated at creation, and asserts that it was made in the days of Moses. He also differs with some already quoted in that he denies the perpetuity of the law of ten commandments. In his estimation, the Sabbath was a Jewish institution, absolutely unknown to good men before the time of Moses, and of no authority whatever since the death of Christ. The idea of the change of the Sabbath from the seventh day of the week to the first, is not only never found in his writings, but is absolutely irreconcilable with such statements as the foregoing, which abound therein. And yet Justin Martyr is prominently and constantly cited in behalf of the so-called Christian Sabbath.
