Every mention of the Sabbath and first-day in that ancient book called "Apostolical Constitutions" is now before the reader. This book comes down to us from the third century, and contains what was at that time very generally believed to be the doctrine of the apostles. It is therefore 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. At the time these "Constitutions" were put in writing, the ten commandments were revered as the immutable rule of right, and 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. But the first-day festival had already 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 are treated as distinct institutions, and that no hint of the change of the Sabbath to the first day of the week is ever once given. The "Apostolical Constitutions" are cited first, not because written by the apostles, but because of their title. For the same reason the so-called Epistle of Barnabas is quoted next, not because written by that apostle, for the proof is ample that it was not, but because it is often quoted by first-day writers as the words of the apostle Barnabas. It was in existence, however, as early as the middle of the second century, and, like the "Apostolical Constitutions," is of value to us in that it gives some clue to the opinions which prevailed in the region where the writer lived, or at least which were held by his party. CHAPTER III. Barnabas--Pliny--Ignatius--The Church at Smyrna--The Epistle to Diognetus--Recognitions of Clement--Syriac Documents concerning Edessa. TESTIMONY OF THE EPISTLE OF BARNABAS. In his second chapter this writer speaks thus:-- "For he hath revealed to us by all the prophets that he needs neither sacrifices, nor burnt-offerings, nor oblations, saying thus, 'What is the multitude of your sacrifices unto me, saith the Lord? I am full of burnt-offerings, and desire not the fat of lambs, and the blood of bulls and goats, not when ye come to appear before me: for who hath required these things at your hands? Tread no more my courts, not though ye bring with you fine flour. Incense is a vain abomination unto me, and your new moons and Sabbaths I cannot endure.' He has therefore abolished these things, that the new law of our Lord Jesus Christ, which is without the yoke of necessity, might have a human oblation." The writer may have intended to assert the abolition of the sacrifices only, as this was his special theme in this place. But he presently asserts the abolition of the Sabbath of the Lord. Here is his fifteenth chapter entire:--
