This father wrote about A. D. 270. He participated in the discussion of the question whether the festival of Easter, or passover, should be celebrated on the fourteenth day of the first month, the same day on which the Jews observed the passover, or whether it should be observed on the so-called Lord's day next following. In this discussion he uses the term Lord's day, in his first canon once, quoting it from Origen; in his seventh, twice; in his tenth, twice; in his eleventh, four times; in his twelfth, once; in his sixteenth, twice. These are all the instances in which he uses the term. We quote such of them as shed any light upon the meaning of it as used by him. In his seventh canon he says: "The obligation of the Lord's resurrection binds to keep the paschal festival on the Lord's day." In his tenth canon he uses this language: "The solemn festival of the resurrection of the Lord can be celebrated only on the Lord's day." And also "that it should not be lawful to celebrate the Lord's mystery of the passover at any other time but on the Lord's day, on which the resurrection of the Lord from death took place, and on which rose also for us the cause of everlasting joy." In his eleventh canon he says: "On the Lord's day was it that light was shown to us in the beginning, and now also in the end, the comforts of all present and the tokens of all future blessings." In his sixteenth canon he says: "Our regard for the Lord's resurrection which took place on the Lord's day will lead us to celebrate it on the same principle." The reader may be curious to know why a controversy should have arisen respecting the proper day for the celebration of the passover in the Christian church when no such celebration had ever been commanded. The explanation is this: The festival was celebrated solely on the authority of tradition, and there were in this case two directly conflicting traditions, as is fully shown in the tenth canon of this father. One party had their tradition from John the apostle, and held that the paschal feast should be celebrated every year "whenever the fourteenth day of the moon had come, and the lamb was sacrificed by the Jews." But the other party had their tradition from the apostles Peter and Paul that this festival should not be celebrated on that day, but upon the so-called Lord's day next following. And so a fierce controversy arose which was decided in A. D. 325, by the council of Nice, in favor of Saint Peter, who had on his side his pretended successor, the powerful and crafty bishop of Rome. The term Lord's day is never applied to Sunday till the closing years of the second century. And Clement, who is the first to make such an application, represents the true Lord's day as made up of every day of the Christian's life. And this opinion is avowed by others after him.
