Symbolism of the Heraldic Emblems

Arms: The two scrolls represent the Old and New Testaments, and allude to Bishop Mathieu’s work as a biblical scholar. The colour blue, often associated with the Virgin Mary, refers to his membership in the congregation of the Society of Mary (Marist Fathers). For Bishop Mathieu, gold evokes divinity. The star is a symbol of the Virgin Mary, the Nativity and the Epiphany. Numbering three, the stars allude to the Holy Trinity.

Motto: This Latin phrase, meaning “Do not be afraid,” evokes two important passages in the New Testament: when Joseph is urged to accept Mary into his home, and when Jesus calls Simon, the future Peter, to join his ministry.
