THE CREST OF CARDINAL GIBBONS HIGH SCHOOL HAS GREAT SIGNIFICANCE.
In the upper right-hand corner is the crest of the Archdiocese of Miami, a palm tree planted between two crosses. The flowing waters surrounding the base of the crest signify the State of Florida.
In the upper left-hand corner is the coat of arms of James Cardinal Gibbons with The words, Emitte Spiritum Tuum meaning "Send forth thy Spirit."
In 1886 Gibbons was elevated to Cardinal Archbishop of Baltimore, becoming the second American, to attain that rank in the Catholic Church.
The bottom half of the crest is reserved for the shields of the two religious communities who have taught at Cardinal Gibbons. The one to the left is the Franciscan emblem, the stigmata of Saint Francis extended over the hand of Christ. The one to the right is the Piarist emblem. On the Piarist shield is Mary, the Mother of God, in Greek lettering. Her crown above the Latin "Maria" symbolizes her endless reign over the Order and her inspirational guidance over schools.
Stretching across the bottom of the Crest is the Latin world "Excelsior," the school motto, encouraging the students "ever onward".
