December 21
The saints and feasts remembered on December 21, each with a short life, a Bible passage and a prayer.
Saint Peter Canisius
Wrote catechisms that taught the faith to generations of German Catholics
Peter Canisius was born in 1521 in Nijmegen, in today’s Netherlands. While a student in Cologne he went to Mainz to meet Peter Faber, one of the first Jesuits, made the Spiritual Exercises with him there, and in 1543 joined the young Society of Jesus.
He spent most of his life in German-speaking lands, at a time when the Reformation had divided towns and families. He preached for years in Augsburg cathedral, helped found Jesuit colleges in cities such as Munich, Innsbruck and Prague, and led his order in southern Germany. His catechisms, written from 1555 onward in simple question-and-answer form, were reprinted again and again and used for centuries. He travelled constantly, often worn out, and in his letters he urged fellow Catholics to deal with Protestants patiently rather than with insults.
He spent his last years in Fribourg, Switzerland, where he founded a college and died on 21 December 1597. Pope Pius XI canonised him in 1925 and named him a Doctor of the Church.
Preach the word; be prepared in season and out of season; reprove, rebuke, and encourage with every form of patient instruction.
2 Timothy 4:2 · BSB
A prayer
God of truth, you gave Peter Canisius a patient heart and clear words to teach your Gospel in a divided age. Help us to know our faith well, to share it simply, and to speak with kindness even to those who disagree with us, through Jesus Christ our Lord. Amen.
Saint Micah
Village prophet who called Judah to do justice, love mercy and walk humbly
Micah came from Moresheth, a small town southwest of Jerusalem. According to the book that bears his name, he spoke in the second half of the 700s BC, under the kings Jotham, Ahaz and Hezekiah of Judah, when the prophet Isaiah was also active. Nothing is known about how he died.
Micah was a countryman who saw what the powerful were doing to small farmers: seizing their fields, cheating with false scales, while judges and priests worked for bribes. He warned that even Jerusalem would be ploughed like a field. About a century later, when Jeremiah was on trial for a similar warning, some elders remembered Micah’s words, and Jeremiah was spared.
His short book also holds hope: a ruler would come from little Bethlehem, a text Matthew’s Gospel links to the birth of Jesus. And many Christians know by heart Micah’s summary of what God asks: justice, mercy and humility.
He has shown you, O man, what is good. And what does the LORD require of you but to act justly, to love mercy, and to walk humbly with your God?
Micah 6:8 · BSB
A prayer
God of justice, you sent your prophet Micah to defend the poor and to call your people back to what you truly ask of them. Give us the courage to act justly, the heart to love mercy, and the humility to walk with you each day, until your peace fills the earth. Amen.
