Because the Diocese is a dual-city See, the coat of arms has been divided in half, each half to honor one of the See cities. The upper portion of the diocesan arms honors the city of Pensacola. These arms are composed of a red field on which is placed a gold cross, of The Faith. In the center of the cross is a white plate on which is a representation of the Sacred Heart, to honor the titular of the Cathedral. In the upper left, known as the chief dexter, is a white airplane propeller to denote that Pensacola is principally known for the largest U.S. naval aviation training school in the world.
The lower portion of the diocesan coat of arms contains symbolism of the city of Tallahassee. These arms are composed of a white field on which is displayed a red saltair which is taken from the flag of the State of Florida, of which Tallahassee is the capital. In the compartments formed by the saltair are three black Morecocks (symbol of the More family) to honor the titular of the Co-Cathedral, St. Thomas More; the black log cabin signifies that the Indian word “Tallahassee” means “old town” or “old fields.”
A bishop’s miter appears at the top of the coat of arms to signify that this is the coat of arms of a diocese.
