English: The coat of arms of the Diocese of Burlington. It is composed of a green field

which meets a gold chief (upper one-third of the design) at a jagged line (the dancette) to give the impression of green mountain peaks, thus honoring the Green Mountain State of Vermont, which is the Diocese of Burlington. Below the mountain is a golden stag’s head that is taken from the arms of Lord Cavendish, Earl of Burlington, for whom the See City is named. Between the stag’s antlers, as seen also in the arms of the Archdiocese of Boston, is a golden cross fleuretty. This cross, honoring the French missionaries who first brought The Faith to the region, signifies that the first priest to be stationed in the service of the people of Vermont, Father Jeremiah O’Callaghan, was sent by Bishop Benedict Fenwick of Boston.
