We believe in the same organization that existed in the Primitive Church, namely, apostles, prophets, pastors, teachers, evangelists, and so forth. -Sixth Article of Faith
The Fellowship is a nondenominational form of the Latter Day Saint movement, or Mormonism. The family is the first layer. Because all that are called may hold the keys of the priesthood, the father and/or mother may be the spiritual leader in the home. This is for them to workout through prayer and revelation. The same is true for same-sex couples. And, in polygamous or polyandrous relationship, it is recommended the decision be put to a vote.
Multiple families that worship together as a small congregation become a Synagogue, named after the home temple they worship in. Synagogue literally means “bring together.” These are lead by a Pastor (a lone Bishop). A larger congregation would need to meet in a temple, a building bought by the local Congregation and dedicated to worshiping the Lord. A Congregation shouldn’t exceed one hundred fifty adult seekers and disciples (Mosiah 9:51 RAV, 18:18 OPV).
Congratulations should be lead by members of the High Priesthood holders known as a Bishopric: a High Priest, a High Priestess, and a First Deacon. These three should act as one, are called of the Lord, and sustained by the congregation. They are to be supported by one male and one female first elder and one male and one female first deacon.
Groups of congregations are to be led by a Council of Evangelists, made of members of each congregation and lead by a Patriarch and a Matriarch. In new areas, these are setup by members of the seventy. The Evangelists travel between Congregations, preaching and laboring as needed.
The Fellowship is lead by the First Presidency and the Council of Elders. One may be a member of other Latter Day Saint denominations and still be counted as members of the Fellowship.
