Yvan Mathieu

While serving as a priest, Mathieu was a teacher and pastoral agent at the Séminaire des Pères Maristes, a collaborator at Saint Clare of Assisi parish in Quebec, head of assistance to the poor for Maison Revivre and co-animator of the La Relève Movement. As an academic, he worked as a lecturer at Saint Paul University and became dean of the Faculty of Theology. He also served as the provincial superior of the Marist Fathers in the Canada East Province.^[3]

He is a member of the Society of Biblical Literature.^[3]

On March 17, 2022, Pope Francis appointed Mathieu as auxiliary bishop of the Archdiocese of Ottawa-Cornwall and titular bishop of the see of Vazari.^[3]

Bishop Mathieu's coat of arms contains the classic green galero with six tassels and a processional cross which are almost always included in a bishop's coat of arms.^[4] It also prominently features two scrolls representing the Old and New Testaments in references to his work as a biblical scholar. The blue on the shield represents the Blessed Virgin Mary and references his membership in the Society of Mary. The gold in the centre represents divinity, and the three stars represent Mary, the Nativity, and the Epiphany, as well as the Holy Trinity.^[5]

The Latin motto "NOLI TIMERE" translates to "Do not be afraid." This phrase is meant to evoke the biblical passages in which Joseph is told to take Mary as his wife (Matthew 1:20, Luke 1:30) and Peter is called to join Jesus' ministry (Luke 5:10).^[5]
