The purpose of IACK is to bring the message of Christ to all people; to support the Pope and the bishops, priests and religious throughout the world; to nurture the faith of its members and of Catholics in general, encouraging them to play a generous part in the life and mission of the Church; to foster the unity of its members through prayer, and to promote the establishment of Orders of Catholic Knights where they do not yet exist. It is strongly committed to defending the dignity of life in every phase, promoting social justice, and calling for vigilance in relation to genetic engineering, cloning and their unpredictable consequences. In its evangelising work, IACK gives ample scope to cooperating with other Catholic International Organisations.
