The office of grand master continued to be vested in the Holy See until 1928, when Pius XI again appointed the patriarch of Jerusalem as “rector et administrator.” A complete reorganization of the order was made by Pope Pius XII. By apostolic letter of July 16, 1940, he appointed a cardinal as the “Patronus seu Protector” of the order. In a _Motu proprio_ of Aug. 15, 1945, he assigned the Church and the monastery of St. Onophrius in Rome as the Order’s official center. Finally, by Apostolic Letter _Quam Romani Pontifices_ of Sept. 14, 1949, the pope promulgated complete new statutes for the Order.[28] If, up to that date, more and more the order had assumed the character of an order of merit, this new constitution gives it explicitly a definite purpose. The objective is “to revive in modern form the spirit and ideal of the Crusades, with the weapons of the faith, the apostolate, and christian charity.” More specifically the purpose consists in “the preservation and the propagation of the faith in Palestine, assistance to and development of the missions of the Latin patriarchate of Jerusalem, providing for its charitable, cultural and social undertakings and the defense of the rights of the Catholic church in the Holy Land, the cradle of the order.” The order, as a “juridical person,” is placed under the protection of the Supreme Pontiff who appoints a cardinal as the grand master. The order consists of five classes. The first—and very exclusive—class consists of the “Knights of the Collar,” numbering no more than twelve persons. In addition this same degree belongs by right to the grand master, the cardinal secretary of his Holiness, the cardinal secretary of the Sacred Congregation of the Oriental church and the Latin patriarch of Jerusalem. Besides this special class there are four degrees, both for knights and ladies: grand cross, commanders with plaque (grand officers), commanders and knights. The distinctive emblem, in its more or less elaborate forms according to the various ranks, is the five-double cross which in the present document is constantly designated as the cross of Godfrey of Bouillon.[29] Besides conferring knighthood, the Order of the Holy Sepulchre grants three honorary decorations as marks of distinction: the “Palm of the order,” “the Cross of Merit” which can also be bestowed on non-Catholics, and the “Pilgrim’s Shell” which is given to those knights and dames of the order who visit the Holy Land.
