The Emblem of the order dates from May 12, 1883.  A quick glance at the emblem indicates  a shield mounted upon the cross of Malta.  The Shield is that associated with a  medieval Knight.  The cross of Malta is the representation in a traditionally artistic design of the Cross of Christ through which all graces of redemption were procured for mankind.  This then, represents the Catholic spirit of the Order.  Mounted on the shield are three objects, a mace standing vertically, and crossed behind it, an anchor and a dagger or short sword.  The mace from Roman days is symbolic of authority which must exist in any tightly bonded and efficiently operating organization.  The anchor is the mariner's symbol for Columbus, patron of the Order.  While the short sword or dagger was the weapon of the Knight when engaged upon an errand of mercy.  Thus, the shield expresses Catholic Knighthood in organized merciful action and with the letters K of C. it proclaims this specific form of activity.
The red, white and blue in the background of the shield of the Cross of Malta are the colors of our beloved country. Red is the symbol of stout-hearted courage. Blue is the symbol of hope. White is the symbol of nobility of purpose.

Faith... Hope... Charity...

Red is then the symbol of Faith, of belief in Christ, in the Redemptive and in the mission of every man to spread the knowledge and love of Jesus Christ. White is the color of the Eucharistic Host, symbolizing that God's presence among men. White is then the symbol of Christ like Charity. Blue is the color of our Lady's mantle, in which she draped her beloved Son, through whom salvation came to a sinful world. Blue is then the symbol of Hope.
