A time frequently chosen for prayer or for other devout practices, whether by individuals in private, or in public by congregations or special organizations in parishes, in religious communities, seminaries, or schools. The form of prayer or devotion depends upon the occasion or purpose of the triduum. The three days usually precede some feast, and the feast then determines the choice of the pious execises. In liturgical usage there is a triduum of ceremonies and prayers in Holy Week ; the Rogation Days ; the three days of litanies prior to the feast of the Ascension, and the feasts of Easter and Pentecost, with the first two days of their octaves. There is ecclesiastical authorization for a triduum in honour of the Holy Trinity, of the Holy Eucharist, and of St. Joseph. The first of these, instituted Pius IX, 8 August, 1847, may be made at any time of the year in public or private, and partial or plenary indulgences are attached to it on the usual conditions. The second, also indulgenced, was instituted by Pius X, 10 April, 1907, for the purpose of promoting frequent Communion . The time for it is Friday, Saturday, and Sunday after the feast of Corpus Christi , though the bishops may designate any other more convenient time of the year. Each day there should be a sermon on the Holy Eucharist and Benediction of the Blessed Sacrament, and on Sunday, there should be besides a sermon on the Gospel and on the Holy Eucharist, at the parochial Mass. This triduum is specially for cathedral churches , though the bishops may also require other churches to have it. The prayer, "O Most Sweet Jesus" ( Dulcissime Jesu ), as given in the "Raccolta", is appointed for reading during Benediction. The triduum in honor of St. Joseph, prior to his feast on 19 March, was recommended by Leo XIII in the Encyclical "Quamprimum pluries" (15 August, 1889), with the prayer, "To thee, O blessed Joseph." The most frequent occasions for a triduum are: when children are in preparation for their first Communion; among pupils in school at the beginning of the scholastic year; among seminarians at the same time ; and in religious communities for those who are to renew their vows yearly or every six months. The exercises of these triduums are mainly meditations or instructions disposing the hearers to a devout reception of the sacraments of penance and of Holy Communion and to betterment of life.
The Catholic Encyclopedia is the most comprehensive resource on Catholic teaching, history, and information ever gathered in all of human history. This easy-to-search online version was originally printed between 1907 and 1912 in fifteen hard copy volumes.
Designed to present its readers with the full body of Catholic teaching, the Encyclopedia contains not only precise statements of what the Church has defined, but also an impartial record of different views of acknowledged authority on all disputed questions, national, political or factional. In the determination of the truth the most recent and acknowledged scientific methods are employed, and the results of the latest research in theology, philosophy, history, apologetics, archaeology, and other sciences are given careful consideration.
No one who is interested in human history, past and present, can ignore the Catholic Church, either as an institution which has been the central figure in the civilized world for nearly two thousand years, decisively affecting its destinies, religious, literary, scientific, social and political, or as an existing power whose influence and activity extend to every part of the globe. In the past century the Church has grown both extensively and intensively among English-speaking peoples. Their living interests demand that they should have the means of informing themselves about this vast institution, which, whether they are Catholics or not, affects their fortunes and their destiny.
