A famous mystical theologian, b. in Oisterwijk near Hertogenbosch (Boisle-Duc), Holland, in 1507; d. 19 July, 1578. After finishing his classical studies in the school of the Hieronymites, he studied philosophy, theology, and canon law at Louvain, but refused to take his doctor's degree. In 1530 he was ordained priest, and then settled in Cologne in order to devote himself to higher studies and the practice of Christian perfection. At the same time he became the private tutor of a number of young men, mainly university students. Blessed Peter Canisius and Lawrence Surius are the most celebrated of his pupils. In Cologne, too, he contracted a close friendship with several members of the Carthusian Order, among whom Johann Landsberger, Gerhard Homontanus, and Theodorich and Bruno Loher are worthy of special mention. Though his feeble health did not allow him to become a member of the order, he lived in the monastery, for a time at least, and followed its rule of life as closely as possible. In 1538 Nicolaus was appointed pastor of the Béguinage at Diest; after a year he surrendered his charge for a time, but took it up again with such success that after his death he was commonly spoken of as the saintly Father Eschius. He was also instrumental in founding several diocesan seminaries according to the rules laid down by the Council of Trent. Among his literary works the following are worthy of note: "Introductio in vitam introversam", which is really an introduction to a new edition of the "Templum animae" (Antwerp, 1563 etc.); "Exercitia theologiae mysticae, seu exercitia quaedam pia, quae compendio hominem ad vitam perfectam instituendam juvare possunt" (Antwerp, 1563).

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.
