Bishop Yvan’s Coat of Arms

The arms are shown with the traditional heraldic attributes of a bishop: a green galero, or  ecclesiastical hat, with six green tassels suspended from each side, and a gold processional cross. 

The three stars symbolize the Holy Trinity. They may refer to two biblical scenes: “I see him, but  not now; I behold him, but not near – a star shall come out of Jacob” (Numbers 24:17) and “In the  time of King Herod, after Jesus was born in Bethlehem of Judea, wise men from the East came to  Jerusalem, asking, ‘Where is the child who has been born king of the Jews? For we observed his  star at its rising, and have come to pay him homage.’” (Matthew 2:1-2) They also evoke the Virgin  Mary and the Marian Hymn: Ave Maris Stella, “Hail, star of the sea”. 

The motto Noli timere is translated as “Do not be afraid.” It comes from what Jesus said to Peter  in Luke 5:10, a text that was proclaimed during his episcopal ordination: “Do not be afraid. From  now on you will catch men.” The same expression is found in the words of the Angel of the Lord  to Joseph in the Gospel of Matthew (1:20): “Joseph, son of David, do not be afraid to take to you  Mary your wife, for that which is [a]conceived in her is of the Holy Spirit.” These words are  addressed to Bishop Mathieu in the face of the task that falls to him as a bishop, but also to all  those for whom he will fulfill the ministry of bishop.
