Peter Canisius

Peter Canisius SJ (Dutch: Pieter Kanis; 8 May 1521 – 21 December 1597) was a Dutch Jesuit priest known for his strong support for the Catholic faith during the Protestant Reformation in Germany, Austria, Bohemia, Moravia, Switzerland and the British Isles. The restoration of the Catholic Church in Germany is largely attributed to the work there of the Jesuits, which Canisius led. He is venerated in the Catholic Church as a saint and as a Doctor of the Church.

He was born in 1521 in Nijmegen in the Duchy of Guelders, which, until 1549, was part of the Habsburg Netherlands within the Holy Roman Empire and is now the Netherlands. His father was a wealthy burgermeister, Jacob Kanis. His mother, Ægidia van Houweningen, died shortly after Peter's birth. He was sent to study at the University of Cologne, where he earned a master's degree in 1540, at the age of 19.

While there, he met Peter Faber, one of the founders of the Society of Jesus. Through him, Canisius became the first Dutchman to join the newly founded Society of Jesus in 1543. Canisius finished his studies in theology and then was ordained in 1546. Through his preaching and writings, Peter Canisius became one of the most influential Catholics of his time. He supervised the founding and maintenance of the first German-speaking Jesuit colleges, often with little resources at hand. At the same time he preached in the city and vicinity, and debated and taught in the university.

Canisius exerted a strong influence on the Emperor Ferdinand I. The king's eldest son (later Maximilian II) appointed Phauser, a married priest, to the office of court preacher. Canisius warned Ferdinand I, verbally and in writing, and opposed Phauser in public disputations. Maximilian was obliged to dismiss Phauser and, on this account, the rest of his life he harboured a grudge against Canisius.

In 1547 he attended several sessions of the Council of Trent. Canisius was an influential teacher and preacher, especially through his "German Catechism", a book which defined the basic principles of Catholicism in the German language and made them more accessible to readers in German-speaking countries. He was offered the post of Bishop of Vienna in 1554, but declined in order to continue his traveling and teachings. He did, however, serve as administrator of the Diocese of Vienna for one year, until a new bishop was appointed for it.

He moved to Germany, where he was one of the main Catholic theologians at the Colloquy of Worms in 1557, and later served as the main preacher in the Cathedral of Augsburg from 1559 to 1568, where he strongly witnessed to his faith on three or four occasions each week. Canisius was renowned as a popular preacher. In 1562 he founded what was to become the University of Innsbruck.

In Christ The King – Lord of History by Anne W. Carroll, it states:

Protestantism had made much headway in Germany because many intellectuals had adopted it, making Catholicism appear to be the religion of the ignorant. By his debates, his writing and his teachings, Peter showed that Catholicism was thoroughly rational, that the Protestant arguments were not convincing.
