To know, love, and serve God is the mission of the Catholic faithful.  That mission is reflected in Section 2 of the Charter of the Knights of Columbus:

The purposes for which said corporation is formed, always consistent with Catholic values and doctrine, are the following: 

(a) through a system of subordinate councils, along with regional, national, and international convocations, to raise up, support and encourage a fraternity whose members are practical Catholics united by their faith and by the principles of charity, unity, fraternity, and patriotism; 

(b) through common worship, charitable works, meetings, and rites of initiation, to form its members in Catholic faith and virtue; 

(c) to render pecuniary aid to its members, their families, and beneficiaries of members and their families; 

(d) to render mutual aid and assistance to its sick, disabled, and needy members and their families; 

(e) to promote social and intellectual interaction among its members and their families; 

(f) to promote and conduct educational, charitable, religious, social welfare, war relief, public relief,  and other activities; and 

(g) to unite members in their Catholic identity and the practice of their Catholic faith.
