The term was used in 2005 by John Plummer, in The Many Paths of the Independent Sacramental Movement,[2] and was used earlier, in 2002, by Richard Smoley in his Inner Christianity.[3]
Terminology
The movement's name is an expansion of an earlier term: the Independent Orthodox, Catholic, and Anglican Movement, which was used extensively during many years when many of these groups cooperated, although they were not in formal communion with one another. The majority of these groups' holy orders and sequences of apostolic succession are derived through mutually-common sources, especially Arnold Harris Mathew, Aftimios Ofiesh, Carlos Duarte Costa, and Joseph René Vilatte. It remains difficult to define the ISM as an entity and to distinguish it from the closely related Independent Catholic movement; the two terms are sometimes used interchangeably, seemingly to refer to the same reality.[4]: 152

One relatively underreported segment of the incredible spiritual mosaic which is Western religious life today is the large number of small independent churches of sacramental, Catholic style and practice. Mostly of Anglican, Eastern Orthodox, or Roman Catholic derivation and character, they emphasize the importance of the sacraments, and generally claim authentic apostolic succession.

She sought a bishop to ordain her in the Independent Sacramental Movement, a network of self-sustaining faith communities that operate outside the structures of mainstream churches, but that retain the same apostolic succession of these same mainstream churches. As with the Rev. Bingle, the mainstream church hierarchies generally do not recognize the ordinations of clergy in the Independent Sacramental Movement, even though the lineages of these clergy – who ordained whom ordained whom ordained whom – can be traced back to the same foundational ministers.
