Tested by his own principles, the writer of these Constitutions was far advanced in apostasy; for he held a festival, for which he claimed no divine authority, more honorable than one which he acknowledged to be ordained of God. There could be but one step more in this course, and that would be to set aside the commandment of God for the ordinance of man, and this step was not very long afterward actually taken. One other point should be noticed. It is said:— “Let the slaves work five days; but on the Sabbath day and the Lord’s day let them have leisure to go to church for instruction in piety.”[703] The question of the sinfulness of labor on either of these days is not here taken into the account; for the reason assigned is that the slaves may have leisure to attend public worship. But while these Constitutions elsewhere forbid labor on the Sabbath on the authority of the decalogue, they do not forbid it upon the first day of the week. Take the following as an example:— “O Lord Almighty, thou hast created the world by Christ, and hast appointed the Sabbath in memory thereof, because that _on that day_ thou hast made us _rest from our works_, for the meditation upon thy laws.”[704] The Apostolical Constitutions are valuable to us, not as authority respecting the teaching of the apostles, but as giving us a knowledge of the views and practices which prevailed in the third century. As these Constitutions were extensively regarded as embodying the doctrine of the apostles, they furnish conclusive evidence that, at the time when they were put in writing, the ten commandments were very generally revered as the immutable rule of right, and that the Sabbath of the Lord was by many observed as an act of obedience to the fourth commandment, and as the divine memorial of the creation. They also show that the first-day festival had, in the third century, attained such strength and influence as to clearly indicate that ere long it would claim the entire ground. But observe that the Sabbath and the so-called Lord’s day were then regarded as distinct institutions, and that no hint of the change of the Sabbath from the seventh day to the first is even once given. Thus much out of the fathers concerning the authority of the decalogue, and concerning the perpetuity and observance of the ancient Sabbath. The suppression of the Sabbath of the Bible, and the elevation of Sunday to its place, has been shown to be in no sense the work of the Saviour. But so great a work required the united action of powerful causes, and these causes we now enumerate. 1. _Hatred toward the Jews._ This people, who retained the ancient Sabbath, had slain Christ. It was easy for men to forget that Christ, as Lord of the Sabbath, had claimed it as his own institution, and to call the Sabbath a Jewish institution which Christians should not regard.[705]
