Her mother was a Christian Algonquin, taken captive by the Iroquois and given as wife to the chief of the Mohawk clan, the boldest and fiercest of the Five Nations. When she was four, Kateri lost her parents and little brother in a smallpox epidemic that left her disfigured and half blind. She was adopted by an uncle, who succeeded her father as chief. He hated the coming of the Blackrobes (Jesuit missionaries), but could do nothing to them because a peace treaty with the French required their presence in villages with Christian captives. She refused to marry a Mohawk brave and at 19 finally got the courage to take the step of converting. She was baptized with the name Kateri (Catherine) on Easter Sunday. She would not work on Sunday and received no food that day. She told a missionary that she often meditated on the great dignity of being baptized. She was powerfully moved by God’s love for human beings and saw the dignity of each of her people.

She was always in danger, for her conversion and holy life created great opposition. On the advice of a priest, she ran away one night and began a 200-mile walking journey to a Christian Indian village at Sault St. Louis, near Montreal.

For three years she grew in holiness under the direction of a priest and an older Iroquois woman, giving herself totally to God in long hours of prayer, in charity and in strenuous penance. At 23 she took a vow of virginity, an unprecedented act for an Indian woman, whose future depended on being married. She found a place in the woods where she could pray an hour a day—and was accused of meeting a man there!

Her dedication to virginity was instinctive: She did not know about religious life for women until she visited Montreal. Inspired by this, she and two friends wanted to start a community, but the local priest dissuaded her. She humbly accepted an “ordinary” life. She practiced extremely severe fasting as penance for the conversion of her nation. She died the afternoon before Holy Thursday. Witnesses said that her emaciated face changed color and became like that of a healthy child. The lines of suffering, even the pockmarks, disappeared and the touch of a smile came upon her lips. She was beatified in 1980 and canonized in 2012.
