Cosmerism was the name of a short-lived channeling group that originated in September 1972 when a couple (given the names Luke and Mark) channeled the messages of a group of seven angels. These messages were later published as the Book of Cosmer. Following instructions from the angels, Luke and Mark gathered a group of 13, each of whom was given a Cosmerite name: Matthias, Matthew, Judas Secarius, Josephus, Ananda, Peter, James the Elder, Thomas, Paul, Thaddeus, and John the Beloved. Luke and Mark completed the circle. In the summer of 1974 this circle went public with the first study of the Book of Cosmer and The Moon Monk, a periodical.
Cosmerism advocated the Way of Cosmer, which begins with a realization of the creative force innate in all things as the source of creation. Humanity is on a course toward a oneness of people and angels within the larger unity of the creative force.
The Cosmerites were headquartered in Winter Park, Florida. They proposed the building of Ichikama, a wilderness ashram, but it was never constructed, and the group seems to have disbanded within a few years of its formation.
