Selected Mass Reading

Responsorial Psalm — Psalm 33:2-3, 11-12, 20-21

Give praise to the Lord on the harp; sing to him with the psaltery, the instrument of ten strings. Sing to him a new canticle, sing well unto him with a loud noise. But the counsel of the Lord standeth for ever: the thoughts of his heart to all generations. Blessed is the nation whose God is the Lord: the people whom he hath chosen for his inheritance. Our soul waiteth for the Lord: for he is our helper and protector. For in him our heart shall rejoice: and in his holy name we have trusted.

Saints Memorialized Today

Peter Canisius
Peter Canisius Jesuit priest, Theologian, University teacher, Doctor of the Church 1521–1597

Saint Peter Canisius was born on May 8, 1521, in Nijmegen in the Duchy of Guelders (now in the Netherlands). Sent to study at the University of Cologne, he earned his master’s degree at nineteen and there met Peter Faber, who guided him into the newly founded Society of Jesus. In 1543 he became the first Dutch Jesuit, was ordained a priest in 1546, and soon poured himself out for the renewal of Catholic life amid the turmoil of the Reformation. Traveling tirelessly through Germany, Austria, Bohemia, Moravia, Switzerland, and beyond, he preached with clarity and charity, taught in universities, and helped establish Jesuit colleges that formed generations in faith and learning. His enduring gift to the Church was his catechisms, especially the German Catechism, which made Catholic doctrine accessible to ordinary people and strengthened countless communities. Deeply devoted to the Blessed Virgin Mary, he also fostered Marian prayer and sound teaching. After a stroke late in life, he continued to write and preach until his death in Fribourg on December 21, 1597. He is honored as a Doctor of the Church and is patron of the Canisius-Kolleg Berlin. His feast day is December 21.
