“He, therefore, who shall contend that the full Paschal moon can happen before the equinox, disagrees with the doctrine of the Holy Scriptures, in the celebration of the greatest mysteries, and agrees with those who trust that they may be saved without the grace of Christ preventing them,(971) and who presume to teach that they might have attained to perfect righteousness, though the true Light had never by death and resurrection vanquished the darkness of the world. Thus, after the rising of the sun at the equinox, and after the full moon of the first month following in her order, that is, after the end of the fourteenth day of the same month, all which we have received by the Law to be observed, we still, as we are taught in the Gospel, wait in the third week for the Lord’s day; and so, at length, we celebrate the offering of our Easter solemnity, to show that we are not, with the ancients, doing honour to the casting off of the yoke of Egyptian bondage; but that, with devout faith and love, we worship the Redemption of the whole world, which having been prefigured in the deliverance of the ancient people of God, was fulfilled in Christ’s Resurrection, and that we may signify that we rejoice in the sure and certain hope of our own resurrection, which we believe will likewise happen on the Lord’s day. “Now this computation of Easter, which we set forth to you to be followed, is contained in a cycle of nineteen years, which began long since to be observed in the Church, to wit, even in the time of the Apostles, especially at Rome and in Egypt, as has been said above.(972) But by the industry of Eusebius,(973) who took his surname from the blessed martyr Pamphilus,(974) it was reduced to a plainer system; insomuch that what till then used to be enjoined every year throughout all the Churches by the Bishop of Alexandria, might, from that time forward, be most easily known by all men, the occurrence of the fourteenth moon being regularly set forth in its course. This Paschal computation, Theophilus,(975) Bishop of Alexandria, made for the Emperor Theodosius, for a hundred years to come. Cyril(976) also, his successor, comprised a series of ninety-five years in five cycles of nineteen years. After whom, Dionysius Exiguus(977) added as many more, in order, after the same manner, reaching down to our own time. The expiration of these is now drawing near, but there is at the present day so great a number of calculators, that even in our Churches throughout Britain, there are many who, having learned the ancient rules of the Egyptians, can with great ease carry on the Paschal cycles for any length of time, even to five hundred and thirty-two years,(978) if they will; after the expiration of which, all that appertains to the succession of sun and moon, month and week, returns in the same order as before. We therefore forbear to send you these same cycles of the times to come, because, desiring only to be instructed respecting the reason for the
