As Canada entered World War I, a member of the Brothers of the Christian Schools waged another sort of battle. At the Lasallian house of formation in Montréal, novice director Brother Théophanius-Léo Chatillon fought against the half-heartedness of young men entering religious life. He told them, “A strong idea, filled with all the energy of your soul, should dominate you: ‘I wish to be the friend of Jesus, Mary’s child and the hero of souls.’”
Born to devout parents in Nicolet, Québec, Adolphe Chatillon was orphaned at age 9. A gifted student, he entered the Lasallian novitiate in Montréal in 1887, receiving the religious name Théophanius-Léo. He became director of Montréal’s St. Cunegonde School in 1907, adopting the motto, “Make happy in order to make better.”
Within three months, however, Brother Théophanius fell seriously ill and began a long convalescence, during which he taught liturgy and singing to novices. After partially recovering, he was appointed novice director in 1912. His success as a formator led to his appointment as visitor general of North America in 1923, requiring extensive travel to Lasallian communities in Canada and the United States. Despite chronic illness, he carried out these journeys cheerfully.
In 1928, after chairing a commission at the Lasallian general chapter in Belgium, Brother Théophanius was diagnosed with intestinal cancer. Following an unsuccessful operation in Paris, he returned to Montréal, where visitors streamed to his bedside as if on pilgrimage.
Brother Théophanius-Léo died peacefully April 28, 1929. Pope Benedict XVI declared him venerable in 2011.
