Circumcision is made to prove twin errors of the great apostasy, _infant baptism_ and that _the eighth day is the Lord's day_. But the eighth day in the case of circumcision was not the day succeeding the seventh, that is, the first day of the week, but the eighth day of the life of each infant, and therefore it fell on one day of the week as often as upon another. Such is the only argument addressed by Cyprian for first-day sacredness, and this one seems to have been borrowed from Justin Martyr, who, as we have seen, used it about one hundred years before him. It is however quite as weighty as the argument of Clement of Alexandria, who adduced in its support what he calls a prophecy of the eighth day out of the writings of the heathen philosopher Plato! And both are in the same rank with that of Tertullian, who confessed that they had not the authority of Scripture, but accepted in its stead that of custom and tradition! In his "Exhortation to Martyrdom," section 11, Cyprian quotes the larger part of Matt. 24, and in that quotation at verse 20, the Sabbath is mentioned, but he says nothing concerning that institution. In his "Testimonies against the Jews," book i., sections 9 and 10, he says "that the former law which was given by Moses, was about to cease," and that "a new law was to be given;" and in the conclusion of his "Treatise against the Jews," section 119, he says "that the yoke of the law was heavy which is cast off by us," but it is not certain that he meant to include in these statements the precepts of the moral law. TESTIMONY OF DIONYSIUS, BISHOP OF ALEXANDRIA. This father, who was one of Origen's disciples, wrote about A. D. 260. In the first canon of his "Epistle to Bishop Basilides" he treats of "the proper hour for bringing the fast to a close on the day of Pentecost." He has occasion to quote what the four evangelists say of the Sabbath and first-day in connection with the resurrection of Christ. But in doing this he adds not one word expressive of first-day sacredness, nor does he give it any other title than that of plain "first day of the week." The seventh day is simply called "the Sabbath." He also speaks of "the preparation and the Sabbath" as the "last two days" of a six days' fast, at the anniversary of the week of Christ's death.
