At the time, the piece was already long enough and so I focused on parts two and three which gave the most specific liturgical and ceremonial detail. However, as we come to once again mark the feast day of the founder of that glorious Order, I felt compelled to take the time to finally reprint the first of the three parts so that the original article would be available to our readers in its entirety, and so that this day might bring an opportunity to give consideration to the Carthusian liturgical books.

The Carthusian Liturgy
by a Monk of Parkminster[Part One of Three]
In the year 1084, near the feast of the Nativity of St. John the Baptist, St. Bruno with six companions entered the desert of the Chartreuse in order to seek God in solitude. Without any idea of founding a Religious Order, but prompted solely by an intense longing for God which could be satisfied only by a complete separation from the world, he formed in that desolate, ragged, mountainous tract of Dauphine, with his companions of like mind, a little group of hermits living in community. Since resigning the chancellorship of Rheims, he had already for about two years experienced Benedictine monastic life at Molesme under St. Robert, the future founder of the Cistercian Order, and, for a little while, had even lived in a hermitage at Seche-Fontaine. But he was unsatisfied, for the voice of God was inviting him into greater solitude.
It was while they were seeking a place sufficiently remote that the seven travellers called upon St. Hugh, Bishop of Grenoble, to ask for his blessing. In a dream, St. Hugh had seen seven stars; they fell at his feed, then rose up and lead him over wild, mountainous country, to a place known as the Chartreuse. In the midst of this solitude the stars came to rest and there God raised a temple to His glory. When St. Bruno and his six companions knelt before him and spoke of their longing to seek God in solitude, St. Hugh recognised the seven stars of his dream, and with great joy guided them to the desolate stretch of land which was part of his own diocese, about fifteen miles from Grenoble. The saintly Bishop not only helped them materially in the work of building cells, a church and a cloister linking all together, but became their lasting friend and protector; he consecrated the little church and frequently visited the solitaries, sharing their simple life.
Such an introduction is necessary if a true idea of the Carthusian liturgy is to be obtained, for it embraces at once the causes which brought it into existence, the reasons for its characteristics, and the spirit which has preserved its faithful continuity. St. Bruno and his companions were seeking God by means of a solitary contemplative life lived in community. Their intention was to gather the advantages of the eremitical life and at the same time to lessen its dangers by mitigating with it as much of the coenobitical life as experience would prove to be the best proportion. It followed therefore that the usual monastic routine and life of prayer would need modification and adaptation in order that greater solitude might be obtained.
St. Bruno himself was to spend only six years in his beloved solitude at the Chartreuse, for in 1090 he was summoned to Italy by the Pope, Blessed Urban II, an old pupil, who needed the counsel of his former master. He never returned to Dauphine but died in the year 1101 at La Torre in Calabria, where he had made a second foundation when at length he had been allowed by the Pope to return to solitude on condition of remaining near at hand. As has been said, our holy Father had no intention of founding a Religious Order; he therefore wrote no Rule, but was content to take what he needed from the writings of St. Benedict and those who had treated of the solitary and monastic life. For six years he instructed his little community chiefly by his example. For the Divine Office he continued the manner to which he was now accustomed after his period at Molesme, namely, the monastic psalter and the arrangement of the Office according to the Holy Rule of St. Benedict. And for Mass he followed the books and the manner of the place to which God had led him, that is to say, the diocese of Grenoble, which was that of the ancient See of Lyons, to which it was neighbour. Here, too, modifications were necessary both in Mass and Office, to make them suitable for monks living in solitude. Far from the haunts of men, there was no need for pomp or ceremony to surround the worship of God, which would but defeat the end of such a calling. There is about the Carthusian life a certain element of changelessness which arises from its very nature, and by which its spirit and its purpose have been maintained from the beginning. The reason for its existence does not change, neither does its appeal nor the mean by which it fulfills its end. The call to leave the world in order to live for God alone in solitude is the concern of God and the soul; it is a circumstance detached from time, nor need it suffer alteration therefrom. Similarly, as the Carthusian vocation remains the same in any age, to fulfill its purpose there is never any need to adopt new means or re-fashion old ones in order to lead a changing world to God. We have no contact with the world, nor parochial ministry of any kind, no call for popular devotion, and hence it is that the principles and practices which seemed best to our Fathers have been preserved. For such reasons as these the Carthusian liturgy is the simplest and most austere in the Church.
For forty-three years there was no written record of the life at the Chartreuse but in 1127 Guigo, the fifth Prior, wrote the "Consuetudines" -- the Customs. (P.L CLIII, col. 631-760.) The circumstances were as follows. At three places near Chartreuse -- Portes, Saint-Sulpice and Meyriat, groups of men had begun to live a similar life. They had written to the Prior asking him what rule of life they were to follow. He was unwilling to fall in with their request because, as he explains in the Prologue to the Consuetudines, there was really no need for him to write their customs since almost everything was contained in the Letters of St. Jerome, the Rule of St. Benedict and writers of such a character. It was only when the Bishop, St. Hugh, ordered him to do so that he committed to writing the things that they were accustomed to do. Actually, of course, he is describing the manner of life instituted by St. Bruno, for Guigo makes it quite clear that he is describing the things of which he is a witness, and is not in any way a lawgiver. In the Consuetudines is contained the basis of the whole of the Carthusian life, both for the Fathers and the Brothers. He begins with what he terms "the section of greater dignity, that, namely, which concerns the Divine Office, in which for the most part, we follow the way of other monks, especially in the ordering of the psalms."

In 1142, under St. Anthelme the 7th Prior, there was instituted the General Chapter, on which occasion other communities in the neighbourhood of the Chartreuse leading a similar life were united under the authority of the Prior of the Chartreuse and the General Chapter. The first act was to bring about uniformity in the liturgy. (P.L. CLIII, col. 1126.) Then, in 1259 were promulgated what are known as the Statuta Antiqua, and the evolution of the liturgical texts and rites was now fixed. It had been the custom to mingle directions concerning the liturgy and discipline with each other in the Statutes, but in 1582 all liturgical matter was removed and made into a separate book known as the Ordinarium Finally in 1603 the Missal was corrected in conformity to the revision ordered by the Council of Trent; and in 1687 a revision of all liturgical books was ordered by the Sacred Congregation of Rites. These revisions were concerned merely with producing conformity with the Vulgate, and affected only words.
Before treating of the actual procedure of the Mass and Office it will be necessary to give a brief description of the life in a Charterhouse and how the liturgy and that life interact. The Carthusian life, as it has been said, is a blending of solitary and community life. Reasons have already been given why the solitude of the community as a whole has left an impress on the liturgy; we shall now see the influence upon it of the solitude of the individual in the community. The Carthusian monk lives alone in a cell which consists of a little house and garden. The cells are quite separate, and there is complete privacy. A certain spaciousness is essential in a Charterhouse to ensure that sense of being alone which a room on a corridor does not provide. The ground-floor of the cell is a workshop; the upper floor consists of two rooms in the larger of which the monk passes most of his life. In a corner is the oratory which is furnished like a choir stall; his bed is in an alcove; there is a bookcase, a table for study and a place near the window where he takes his food. The silence is intense.

But there are certain days, namely Sundays, Chapter Feasts and Solemnities, when the Carthusian leads more of a community life. On such days all the Divine Office is sung in choir, except Compline which is always said in the cell; the monk attends Chapter, takes his food in the refectory, and he may, if he wishes, take recreation or colloquium with his brethren after None. Such days are an integral part of Carthusian life and have been observed from the earliest days of the Order. They are reminiscent of the custom of the ancient solitaries of the desert who on Sundays and Feasts met their brethren for the celebration of the sacred Mysteries which was followed by a meal taken in common.
It will be readily observed that if the number of such Feasts be allowed to grow unchecked, the chief purpose of our vocation would be greatly impeded; hence the swing of increase and reduction in their numbers as the centuries pass. The earlier calendar that we possess belongs to the year 1134 -- just seven years after the "Consuetudines." It is practically the early Roman calendar from the beginning of the ninth to twelfth century. In the following numbers no account is is taken of Sundays, nor of the possibility of such feasts falling on a Sunday, which would add complication -- though it should be noticed that as no feasts were transferred in the early days of the Order while some now are, there would be a slight difference in favour of the earlier numbers. In 1134 there were 33 Chapters Feasts and Solemnities; by the end of the century, 38; the numbers for the next three centuries are 39, 51 and 54 respectively. By the end of the 16th century the maximum is reached -- 69; then begins the reduction: in 1603 the number has already fallen to 63, and thus it continues to decrease until in 1914, as also today, there are only 40 such days -- about the same number as at the beginning.
