When knighthood was in flower, knights carried the sword to defend their God, their Church, their country and their fellow man according to the code of chivalry. Today, Sir Knights wear regalia and carry the sword to honor Christ and His apostles, especially on religious and civic occasions specified in this manual. Hence, the primary purpose of the Fourth Degree is to encourage active Catholic citizenship and foster the spirit of patriotism in members and the community at large.

The public appearance of Fourth Degree Knights as a Color Corps at religious and civic functions is an important activity of each assembly. Their colorful capes and chapeaux add dignity and the pride of Church and country to any event. By these public demonstrations their loyalties bring credit to themselves and to the Knights of Columbus.
