A monogram of the name of Jesus Christ . From the third century the names of our Saviour are sometimes shortened, particularly in Christian inscriptions (IH and XP, for Jesus and Christus). In the next century the "sigla" ( chi-rho ) occurs not only as an abbreviation but also as a symbol. From the beginning, however, in Christian inscriptions the nomina sacra , or names of Jesus Christ , were shortened by contraction, thus IC and XC or IHS and XPS for Iesous Christos . These Greek monograms continued to be used in Latin during the Middle Ages . Eventually the right meaning was lost, and erroneous interpretation of IHS led to the faulty orthography "Jhesus". In Latin the learned abbreviation IHC rarely occurs after the Carlovingian era. The mongram became more popular after the twelfth century when St. Bernard insisted much on devotion to the Holy Name of Jesus, and the fourteenth, when the founder of the Jesuati, Blessed John Colombini (d. 1367), usually wore it on his breast. Towards the close of the Middle Ages IHS became a symbol, quite like the chi-rho in the Constantinian period. Sometimes above the H appears a cross and underneath three nails, while the whole figure is surrounded by rays. IHS became the accepted iconographical characteristic of St. Vincent Ferrer (d. 1419) and of St. Bernardine of Siena (d. 1444). The latter holy missionary, at the end of his sermons, was wont to exhibit this monogram devoutly to his audience, for which some blamed him; he was even called before Martin V. St. Ignatius of Loyola adopted the monogram in his seal as general of the Society of Jesus (1541), and thus it became the emblem of his institute. IHS was sometimes wrongly understood as "Jesus Hominum (or Hierosolymae) Salvator", i.e. Jesus, the Saviour of men (or of Jerusalem =Hierosolyma).

Catholic Encyclopedia

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.
