Chap. XXI. How the Abbot Ceolfrid sent master-builders to the King of the Picts to build a church, and with them an epistle concerning the Catholic Easter and the Tonsure. [710 a.d.] (2)

“And these men, receiving in themselves the recompense of their error, when they place Easter Sunday on the twenty-second day of the month, openly transgress and do violence to the term of Easter appointed by the Law, seeing that they begin Easter on the evening of that day in which the Law commanded it to be completed and brought to an end; and appoint that to be the first day of Easter, whereof no mention is any where found in the Law, to wit, the first of the fourth week. And both sorts are mistaken, not only in fixing and computing the moon's age, but also sometimes in finding the first month; but this controversy is longer than can be or ought to be contained in this letter. I will only say thus much, that by the vernal equinox, it may always be found, without the chance of an error, which must be the first month of the year, according to the lunar computation, and which the last. But the equinox, according to the opinion of all the Eastern nations, and particularly of the Egyptians,966 who surpass all other learned men in calculation, falls on the twenty-first day of March, as we also prove by horological observation. Whatsoever moon therefore is at the full before the equinox, being on the fourteenth or fifteenth day, the same belongs to the last month of the foregoing year, and consequently is not meet for the celebration of Easter; but that moon which is full after the equinox, or at the very time of the equinox, belongs to the first month, and on that day, without a doubt, we must understand that the ancients were wont to celebrate the Passover; and that we also ought to keep Easter when the Sunday comes. And that this must be so, there is this cogent reason. It is written in Genesis,967 ‘And God made two great lights; the greater light to rule the day, and the lesser light to rule the night.’ Or, as another edition968 has it, ‘The greater light to begin the day, and the lesser to begin the night.’ As, therefore, the sun, coming forth from the midst of the east, fixed the vernal equinox by his rising, and afterwards the moon at the full, when the sun set in the evening, followed from the midst of the east; so every year the same first lunar month must be observed in the like order, so that its full moon must not be before the equinox; but either on the very day of the equinox, as it was in the beginning, or after it is past. But if the full moon shall happen to be but one day before the time of the equinox, the aforesaid reason proves that such moon is not to be assigned to the first month of the new year, but rather to the last of the preceding, and that it is therefore not meet for the celebration of the Paschal festival.

“Now if it please you likewise to hear the mystical reason in this matter, we are commanded to keep Easter in the first month of the year, which is also called the month of new things, because we ought to celebrate the mysteries of our Lord's Resurrection and our deliverance, with the spirit of our minds renewed to the love of heavenly things. We are commanded to keep it in the third week of the same month, because Christ Himself, who had been promised before the Law, and under the Law, came with grace, in the third age of the world, to be sacrificed as our Passover; and because rising from the dead the third day after the offering of His Passion, He wished this to be called the Lord's day, and the Paschal feast of His Resurrection to be yearly celebrated on the same; because, also, we do then only truly celebrate His solemn festival, if we endeavour with Him to keep the Passover, that is, the passing from this world to the Father, by faith, hope, and charity. We are commanded to observe the full moon of the Paschal month after the vernal equinox, to the end, that the sun may first make the day longer than the night, and then the moon may show to the world her full orb of light; inasmuch as first ‘the Sun of righteousness, with healing in His wings,’969 that is, our Lord Jesus, by the triumph of His Resurrection, dispelled all the darkness of death, and so ascending into Heaven, filled His Church, which is often signified by the name of the moon, with the light of inward grace, by sending down upon her His Spirit. Which order of our salvation the prophet had in his mind, when he said ‘The sun was exalted and the moon stood in her order.’970

“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. Cyril976 also, his successor, comprised a series of ninety-five years in five cycles of nineteen years. After whom, Dionysius Exiguus977 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 Paschal time, you show that you have enough of those catholic cycles concerning Easter.

“But having said thus much briefly and succinctly, as you required, concerning Easter, I also exhort you to take heed that the tonsure, concerning which likewise you desired me to write to you, be in accordance with the use of the Church and the Christian Faith. And we know indeed that the Apostles were not all shorn after the same manner, nor does the Catholic Church now, as it agrees in one faith, hope, and charity towards God, use one and the same form of tonsure throughout the world. Moreover, to look back to former times, to wit, the times of the patriarchs, Job, the pattern of patience, when tribulation came upon him, shaved his head,979 and thus made it appear that he had used, in time of prosperity, to let his hair grow. But concerning Joseph, who more than other men practised and taught chastity, humility, piety, and the other virtues, we read that he was shorn when he was to be delivered from bondage,980 by which it appears, that during the time of his bondage, he was in the prison with unshorn hair. Behold then how each of these men of God differed in the manner of their appearance abroad, though their inward consciences agreed in a like grace of virtue. But though we may be free to confess, that the difference of tonsure is not hurtful to those whose faith is pure towards God, and their charity sincere towards their neighbour, especially since we do not read that there was ever any controversy among the Catholic fathers about the difference of tonsure, as there has been a contention about the diversity in keeping Easter, and in matters of faith; nevertheless, among all the forms of tonsure that are to be found in the Church, or among mankind at large, I think none more meet to be followed and received by us than that which that disciple wore on his head, to whom, after his confession of Himself, our Lord said,981 ‘Thou art Peter, and upon this rock I will build My Church, and the gates of Hell shall not prevail against it, and I will give unto thee the keys of the kingdom of Heaven.’ Nor do I think that any is more rightly to be abhorred and detested by all the faithful, than that which that man used, to whom that same Peter, when he would have bought the grace of the Holy Ghost, said,982 ‘Thy money perish with thee, because thou hast thought that the gift of God may be purchased with money. Thou hast neither part nor lot in this word.’ Nor do we shave ourselves in the form of a crown only because Peter was so shorn; but because Peter was so shorn in memory of the Passion of our Lord, therefore we also, who desire to be saved by the same Passion, do with him bear the sign of the same Passion on the top of our head, which is the highest part of our body. For as all the Church, because it was made a Church by the death of Him that gave it life, is wont to bear the sign of His Holy Cross on the forehead, to the end, that it may, by the constant protection of His banner, be defended from the assaults of evil spirits, and by the frequent admonition of the same be taught, in like manner, to crucify the flesh with its affections and lusts;983 so also it behoves those, who having either taken the vows of a monk, or having the degree of a clerk, must needs curb themselves the more strictly by continence, for the Lord's sake, to bear each one of them on his head, by the tonsure, the form of the crown of thorns which He bore on His head in His Passion, that He might bear the thorns and thistles of our sins, that is, that he might bear them away and take them from us; to the end that they may show on their foreheads that they also willingly, and readily, endure all scoffing and reproach for his sake; and that they may signify that they await always ‘the crown of eternal life, which God hath promised to them that love him,’984 and that for the sake of attaining thereto they despise both the evil and the good of this world. But as for the tonsure which Simon Magus is said to have used, who is there of the faithful, I ask you, who does not straightway detest and reject it at the first sight of it, together with his magic? Above the forehead it does seem indeed to resemble a crown; but when you come to look at the neck, you will find the crown cut short which you thought you saw; so that you may perceive that such a use properly belongs not to Christians but to Simoniacs, such as were indeed in this life by erring men thought worthy of the glory of an everlasting crown; but in that which is to follow this life are not only deprived of all hope of a crown, but are moreover condemned to eternal punishment.
