This witness is brought forward in a manner to give the utmost weight and authority to his words. He was the disciple of that eminent Christian martyr, Polycarp, and Polycarp was the companion of the apostles. What Irenæus says is therefore in the estimation of many as worthy of our confidence as though we could read it in the writings of the apostles. Does not Irenæus call Sunday the Christian Sabbath and the Lord’s day? Did he not learn these things from Polycarp? And did not Polycarp get them from the fountain head? What need have we of further witness that Lord’s day is the apostolic name for Sunday? What if the six earlier witnesses have failed us? Here is one that says all that can be asked, and he had his doctrine from a man who had his from the apostles!
Why then does not this establish the authority of Sunday as the Lord’s day? The first reason is that neither Irenæus nor any other man can add to or change one precept of the word of God, on any pretense whatever. We are never authorized to depart from the words of the inspired writers on the testimony of men who conversed with the apostles, or rather who conversed with some who had conversed with them. But the second reason is that every word of this pretended testimony of Irenæus is a fraud! Nor is there a single instance in which the term Lord’s day is to be found in any of his works, nor in any fragment of his works preserved in other authors![447] And this completes the seven witnesses by whom the Lord’s day of the Catholic church is traced back to and identified with the Lord’s day of the Bible! It is not till A. D. 194, sixteen years after the latest of these witnesses, that we meet the first instance in which Sunday is called the Lord’s day. In other words, Sunday is not called the Lord’s day till ninety-eight years after John was upon Patmos, and one hundred and sixty-three years after the resurrection of Christ!
But is not this owing to the fact that the records of that period have perished? By no means; for the day is six times mentioned by the inspired writers between the resurrection of Christ, A. D. 31, and John’s vision upon Patmos, A. D. 96; namely, by Matthew, A. D. 41; by Paul, A. D. 57; by Luke, A. D. 60, and A. D. 63; and by Mark, A. D. 64; and always as first day of the week. John, after his return from Patmos, A. D. 97, twice mentions the day, still calling it first day of the week.
After John’s time, the day is next mentioned in the so-called epistle of Barnabas, written probably as early as A. D. 140, and is there called “the eighth day.” Next it is mentioned by Justin Martyr in his Apology, A. D. 140, once as “the day on which we all hold our common assembly;” once as “the first day on which God ... made the world;” once as “the same day [on which Christ] rose from the dead;” once as “the day after that of Saturn;” and three times as “Sunday,” or “the day of the sun.” Next the day is mentioned by Justin Martyr in his Dialogue with Trypho, A. D. 155, in which he twice calls it the “eighth day;” once “the first of all the days;” once as “the first” “of all the days of the [weekly] cycle;” and twice as “the first day after the Sabbath.” Next it is once mentioned by Irenæus, A. D. 178, who calls it simply “the first day of the week.” And next it is mentioned once by Bardesanes, who calls it simply “the first of the week.” The variety of names by which the day is mentioned during this time is remarkable; but it is never called Lord’s day, nor ever called by any sacred name.
Though Sunday is mentioned in so many different ways during the second century, it is not till we come almost to the close of that century that we find the first instance in which it is called Lord’s day. Clement, of Alexandria, A. D. 194, uses this title with reference to “the eighth day.” If he speaks of a natural day, he no doubt means Sunday. It is not certain, however, that he speaks of a natural day, for his explanation gives to the term an entirely different sense. Here are his words:—
“And the Lord’s day Plato prophetically speaks of in the tenth book of the Republic, in these words: ‘And when seven days have passed to each of them in the meadow, on the eighth they are to set out and arrive in four days.’ By the meadow is to be understood the fixed sphere, as being a mild and genial spot, and the locality of the pious; and by the seven days, each motion of the seven planets, and the whole practical art which speeds to the end of rest. But after the wandering orbs, the journey leads to Heaven, that is, to the eighth motion and day. And he says that souls are gone on the fourth day, pointing out the passage through the four elements. But the seventh day is recognized as sacred, not by the Hebrews only, but also by the Greeks; according to which the whole world of all animals and plants revolve.”[448]
Clement was originally a heathen philosopher, and these strange mysticisms which he here puts forth upon the words of Plato are only modifications of his former heathen notions. Though Clement says that Plato speaks of the Lord’s day, it is certain that he does not understand him to speak of literal days nor of a literal meadow. On the contrary, he interprets the meadow to represent “the fixed sphere, as being a mild and genial spot, and the locality of the pious;” which must refer to their future inheritance. The seven days are not so many literal days, but they represent “each motion of the seven planets, and the whole practical art which speeds to the end of rest.” This seems to represent the present period of labor which is to end in the rest of the saints. For he adds: “But after the wandering orbs [represented by Plato’s seven days] the journey leads to Heaven, that is, to the eighth motion and day.” The seven days, therefore, do here represent the period of the Christian’s pilgrimage, and the eighth day of which Clement here speaks is not Sunday, but Heaven itself! Here is the first instance of Lord’s day as a name for the eighth day, but this eighth day is a mystical one, and means Heaven!
But Clement uses the term Lord’s day once more, and this time clearly, as representing, not a literal day, but the whole period of our regenerate life. For he speaks of it in treating of fasting, and he sets forth fasting as consisting in abstinence from sinful pleasures, not only in deeds, to use his distinction, as forbidden by the law, but in thoughts, as forbidden by the gospel. Such fasting pertains to the entire life of the Christian. And thus Clement sets forth what is involved in observing this duty in the gospel sense:—
“He, in fulfillment of the precept, according to the gospel, keeps the Lord’s day, when he abandons an evil disposition, and assumes that of the Gnostic, glorifying the Lord’s resurrection in himself.”[449]
From this statement we learn, not merely his idea of fasting, but also that of celebrating the Lord’s day, and glorifying the resurrection of Christ. This, according to Clement, does not consist in paying special honors to Sunday, but in abandoning an evil disposition, and in assuming that of the Gnostic, a Christian sect to which he belonged. Now it is plain that this kind of Lord’s-day observance pertains to no one day of the week, but embraces the entire life of the Christian. Clement’s Lord’s day was not a literal, but a mystical, day, embracing, according to this, his second use of the term, the entire regenerate life of the Christian; and according to his first use of the term, embracing also the future life in Heaven. And this view is confirmed by Clement’s statement of the contrast between the Gnostic sect to which he belonged and other Christians. He says of their worship that it was “not on special days, as some others, but doing this continually in our whole life.” And he speaks further of the worship of the Gnostic that it was “not in a specified place, or selected temple, or at certain festivals, and on appointed days, but during his whole life.”[450]
