Pope John XXIII Assembly is located in Nassau County, New York.  For the Columbian Year 2010 - 2011 the Faithful Navigator is SK Winston Delpesh of the "Robert W. Powell Council". 
Pope John XXIII Assembly upholds the values of the Fourth Degree, Patriotism. We exemplify Patriotism in many ways, such as our "Fly the Flag" program, acknowledging a Sir Knight who flies the flag faithfully.
The most visible arm of the Knights of Columbus and the Assembly is our Honor Guard of the Fourth Degree. The Honor Guard proudly represent the Knights of Columbus at countless parades, council functions, Nassau Chapter functions, Fourth Degree Exemplification Ceremony, Brother Knights funerals, and special masses, including the Annual Pro-Life Mass at St. Patrick's Cathedral, the Annual Bishop's Memorial Mass, and the Annual Mass at Our Lady of the Island Shrine in Eastport, Long Island.
