A Practical Catholic, as defined by the Knights of Columbus: The practical Catholic in union with the Holy See is one who, in general, regulates his life according to the teachings of Christ and the Church, and endeavors to observe the commandments of God and of the Church. A practical Catholic strives to have a greater knowledge of the teachings of Christ and his Church, and to accept, respect and defend the Church's authority (vested in the Supreme Pontiff, the hierarchy and clergy united with him) to teach, govern and sanctify the faithful. A practical Catholic gives material and moral support to the Church and her works on all levels, promoting the programs of the parish and diocese and comes to the aid of the missions, the needy, the underprivileged; espousing and advancing the just causes of minority groups; endeavoring to eliminate unjust discrimination, prejudice, etc.; supporting the Church in her defense of marriage and family life and in her crusades against divorce, abortion, pornography and all the evils of today. If a Catholic marries outside the Church, that is, contrary to the laws of the Church, he ceases to be a practical Catholic and hence may not be a member of the Knights of Columbus. A man who, living in a valid marriage, obtains a civil divorce and remarries outside the Church ceases to be a practical Catholic and hence loses his right to join or continue in the Order of the Knights of Columbus. If his former marriage is declared null by the Church and he remarries validly according to the Church's laws, he may be reinstated into the Order. A Catholic who is a member of a forbidden, secret society is not a practical Catholic and hence may not become or continue to be a member of the Knights of Columbus.
