"The mission of the GCL (the 'League') is to provide opportunities for the integration and development of Christian values into the everyday life of students through interscholastic athletic competition. Exemplary sportsmanship, respect, self-discipline and responsibility are the keystones of the GCL and define their members. Athletic activities enhance the educational, psychological, and physical development of the athletes and build a sense of community that support the overall success of students in our Catholic high schools. The Principals, Commissioners of the League, Athletic Directors and Coaches understand and promote the mission of the League and serve as teachers and role models."
