Coat of arms
;Overview The episcopal heraldic achievement, of bishop's coat of arms, is composed of a shield, with its charges, a motto scroll and the external ornaments. The shield, which is the central most important feature of any heraldic device, is described in archaic 12th century terms, and this description is oriented as if being given by the bearer with the shield worn on the arm.: the terms dexter and sinister are thus the reverse of what they are as seen from the front. ;Arms By heraldic tradition, the arms of the bishop of a diocese, called the "Ordinary" are joined to the arms of his jurisdiction, seen in the dexter impalement of the shield. In this case, these arms of the Diocese of Jackson. These arms are composed of a golden field on which is displayed a red cross "potent." When the City of Jackson was established the second See City for the Diocese of Natchez-Jackson in 1957, the cross that had been used in the arms of Natchez was incorporated into the new design. In 1977 when the diocese was renamed for the new, singular See City of Jackson the cross with a cross arm on each arm was retained to reflect the heritage of The Faith in this portion of the State of Mississippi. Below the cross are wavy blue and silver bars to represent the waters of the Mississippi. For his personal arms, seen in the sinister impalement of the shield, Bishop Latino adopted a design reflecting his life as a priest of the Diocese of Houma-Thibodaux. The design is a saltire with gold and red vertical bars on the top and bottom and silver fields on either side, the ancient arms of the Kingdom of Sicily, to reflect Bishop Latino's Sicilian heritage. In the silver fields on either side of the design the black displayed eagles of the Sicilian arms have been replaced by a blue fleur-de-lis and a blue magnolia blossom to reflect Latino's birthplace of New Orleans and the surrounding region. In the base of the gold bars from the upper portion have been replaced by a golden carpenter's square, issuant from the sides, to honor the bishop's Baptisimal patron, St. Joseph. This arrangement is used in the arms of the Diocese of Houma-Thibodaux where Bishop Latino was serving as Vicar General when he became Bishop of Jackson. ;Motto Bishop Latino's motto is "ut unum sini" ", from St. John's Gospel. ;External The device is completed with the external ornaments which are the processional cross, which is placed in back of the shield and which extends above and below the shield, and a pontifical hat, called a "galero", with its six tassels, in three rows, on either side of the shield, all green. These are the heraldic insignia of the prelate of the rank of bishop by instruction of The Holy See of March 31, 1969.
