12. Therefore it is fit that not only the day of the Passion, but also that of the Resurrection be observed by us, that we may have a day both of bitterness and of joy; fast on the one, on the other be refreshed. Consequently, if the fourteenth moon of the first month fall, as will be the case next time, on the Lord’s day, inasmuch as we ought neither to fast on the Lord’s day, nor on the thirteenth moon which falls on the Sabbath-day to break the fast, which must especially be observed on the day of the Passion, the celebration of Easter must be postponed to the next week. For the fifteenth day of the month follows, on which Christ suffered, and it will be the second day of the week. The third day of the week will be the sixteenth moon, on which our Lord’s Flesh rested in the tomb; and the fourth day of the week will be the seventeenth moon on which our Lord rose again. Sidenote: S. John ii. 19. 13. When therefore these three sacred days run as they do next time into the further week, within which three days He both suffered and rested and rose again, of which three days He says, _Destroy this temple, and in three days I will raise it up_, what can bring us trouble or doubt? For if it raises a scruple that we do not on the fourteenth moon celebrate the particular day either of His Passion or Resurrection, we may remember that our Lord Himself did not suffer on the fourteenth moon, but on the fifteenth, and on the seventeenth He rose again. But if any are troubled at our passing over the fourteenth moon, which falls upon the Lord’s day, that is the 18th of April, and recommending its celebration on the following Lord’s day, there is this authority for doing so. 14. In times lately past, when the fourteenth moon of the first month fell on the Lord’s day, the solemnity was celebrated on the Lord’s day next ensuing. But in the eighty-ninth year of the Era of Diocletian[134], when the fourteenth moon was on the 24th of March, Easter was kept by us on the last day of March. The Alexandrians and Egyptians also, as they wrote themselves, when the fourteenth day of the moon fell on the 28th day of the month Phamenoth, kept Easter on the fifth day of the month Pharmuthi, which is the last day of March, and so agreed with us. Again in the ninety-third year of the Era of Diocletian, when the fourteenth moon fell on the fourteenth day of the month Pharmuthi, which is the 9th of April, and was the Lord’s day, Easter was kept on the Lord’s day, the 21st day of Pharmuthi, or according to us on the 16th of April. Wherefore since we have both reason and precedent, nothing should disturb us upon this head. Sidenote: Deut. xvi. 1.
