English: By heraldic tradition, the arms of the bishop of a diocese, called a “diocesan bishop” or in an ecclesiastical province where the bishop of a certain diocese serves as the “first-among-equals” in that province and is called the “Metropolitan Archbishop,” their are joined (impaled) with the arms of their jurisdiction, in this case the Archdiocese of Hartford, that are seen in the dexter impalement (left side) of the design.

The arms of the archdiocese are referred to as “canting,” (armes pariantes) or “playing on” the name of the See City. Here, on a red field is a golden deer, sometimes called a “hart,” that is standing in a river crossing, of silver (white) and blue, known as a “ford.” Thus, the play is on the name deer-crossing or Hartford. The hart is carrying a Paschal banner, that is described as “Proper, meaning “as it always appears” (gold pole with a burgee (notched-end flag) of white, charged with a red cross). Here the stag is carrying the standard of The Faith across the representation of water, that being the Connecticut River that runs through the See City.

The personal heraldry of Archbishop Coyne, upon a blue (azure) field, is Archbishop Coyne’s coat of arms which blends images representing his love for God, family genealogy and ministry history in the Archdiocese of Boston.

Archbishop Coyne’s grandfathers were Irish and his grandmothers were French. The coat of arms reflects those two heritages with the Celtic cross and the fleur de lis. The Celtic cross also calls to mind the centrality of the cross in the history of salvation and the sacrifice of Jesus which brings redemption. The fleur de lis also represent Mary, the Mother of our Savior, and Saint Joseph, her most chaste spouse. Finally, the blue (azure) field also calls to mind Mary, the Immaculate Conception, under whose patronage the United States of America has been placed.
