The purpose of the Constantinian Orders are to commemorate the first elevation of Christianity from the position of a despised and proscribed heresy to that of a legally recognized and honored religion, to cultivate the social virtues, appeal to the intellectual and moral qualities, preserve as far as possible the customs of the fraternity and bring about good fellowship and understanding between all branches of Masonry.

Knights Companions of the Order meet in Conclaves of the Red Cross of Constantine and a member must be a Royal Arch Mason in good standing and subscribe to a belief in the Christian religion as revealed in the New Testament. Membership is by invitation and each Conclave has a prescribed membership limit.
