The St. Catherine University shield is reserved for the most formal occasions — appearing only on University diplomas, institutional communications and ceremonial documents deemed appropriate by the Office of the President. It is not available for download and may not be used as a graphic element.
The University shield depicts a shield resting upon a pointed oval. The shield incorporates the three aspects of the University: the spiritual, the intellectual and the physical.
The spiritual is represented by the spiked wheel, symbol of St. Catherine of Alexandria, the patron saint of the University. To represent the intellectual aspect, the shield contains the flaming torch of learning, a design also used on the west doors of the University's first building, Derham Hall. The fleur-de-lis on the shield represents the French origins of the Sisters of St. Joseph of Carondelet, founding order of St. Catherine University. The wavy line is the physical symbol of running water that represents the Mississippi River.
The shield is connected with the outer oval at top and at bottom by a sword that passes under the shield and points upward. The sword is a symbol of the great apostle, Paul, and a charge from the coat-of-arms of the Roman Catholic Archdiocese of Saint Paul and Minneapolis. Draped about the blade of the sword above the shield is the motto Progressvm Tvtatvr Pietas, "Devotion to duty safeguards progress."
