Ordo Templi Orientis USA Grand Lodge
The U.S. Grand Lodge is the governing body of the Ordo Templi Orientis in the United States. It is the most populous and active branch of O.T.O., with many local bodies spread throughout the country.
Ordo Templi Orientis is the first of the great Old Æon orders to accept The Book of the Law, received by Aleister Crowley in 1904 EV. This book proclaims a New Æon in human thought, culture and religion. The Æon arises from a single supreme injunction: the Law of Thelema, which is Do what thou wilt.
Ecclesia Gnostica Catholica (E.G.C.), the Gnostic Catholic Church, is the ecclesiastical arm of O.T.O. It confers sacraments including the eucharist of the Gnostic Mass, baptism, confirmation, and ordination. Many celebrations of the Gnostic Mass are open to the public. Those who wish to learn more about O.T.O. are encouraged to attend a Mass; it provides an excellent introduction to O.T.O.'s symbolism and philosophy.
