In practical terms, the priesthood office of seventy is one which has varied widely over the course of history. As originally envisioned by Latter Day Saint movement founder Joseph Smith in the 1830s, the seventy were to be a body composed of several separate quorums of up to 70 seventies each, all of which would be led by seven presidents. These presidents, chosen from the first quorum, would appoint and direct the other quorums of seventy. In the LDS Church, the largest of the Latter Day Saint denominations, the quorums of the seventy are directed and supervised hierarchically by the Quorum of the Twelve Apostles, who are in turn directed by the First Presidency. As introduced by Smith, the apostles and the seventy had authority only outside the main body of Latter Day Saints in Zion, and in the outlying stakes. Members in Zion and the stakes were led by the High Council of Zion and stake high councils. As a body, the seventy in the LDS Church are considered to be equal in priesthood authority with the Quorum of the TwelveApostles. This presumably means that if the apostles were killed or incapacitated, the seventy could take over the function of the apostles. However, in such circumstances, the seventy would be required to act unanimously.
Early Latter Day Saint quorums of seventy
Historically, the First Quorum of the Seventy came into being in 1835 when seven men were set apart as the First Seven Presidents of the Seventy. In 1837, six of the seven presidents were released because it was discovered that they had previously been ordained high priests. Five of these men were ultimately replaced by others. The other two—Levi W. Hancock and Joseph Young—remained members of the First Seven Presidents for the rest of their lives.
Since 2005, the Quorums of the Seventy in the LDS Church have been organized into eight quorums with a presidency of seven. The seventy act as emissaries of the Quorum of the Twelve Apostles and First Presidency of the church in organizing, training, proselytizing, and administering to millions of people scattered all across the globe. The seventy are the layer between local church administration and general church administration. Members of the First and the Second Quorums of the Seventy are general authorities of the church with responsibilities covering the church as a whole. Members of the Third through Twelfth Quorums of the Seventy are called an area seventy and are ordained to the priesthood office of seventy, but they are not general authorities of the church. Area seventies generally have authority only within a geographical unit of the church called an area.
Within Community of Christ, a seventy is also considered to be an elder but is not a High Priest. Part of the function of the seventy is a missionary role and he or she works closely with the apostle in charge of his or her mission field. Seventies are organized into ten quorums, each quorum being presided over by a president. These presidents make up the Council of Presidents of Seventy, and are collectively led by the Senior President of the Presidents of Seventy. All ten quorums are equal with one another. When someone is ordained a seventy, that person automatically becomes a member of one of the Ten Quorums, and remains a member of one of the Quorums so long as that person remains a seventy. In other words, it is not possible to be a seventy and not belong to one of these quorums. The current roster of Presidents of Seventy include:
Quorum I - Tanoh Assoi
Quorum II/X - Larry M. McGuire
Quorum III - Keith E. McMillan/Larry M. McGuire/Karin F. Peter/John S. Wight, Senior President of Seventy
Quorum VII/VIII - John F. Glazer
Quorum IX - Adam R. Wade
Historically, there have always been seven quorums, with a maximum of 70 members each. However, on January 17, 2010, Prophet-President Stephen M. Veazey announced that the number of quorums could be flexible, based on the current needs of the church. The change from seven to ten quorums occurred after the acceptance of Doctrine and Covenants section 164 at the World Conference in April 2010.
There is currently one functioning Quorum of Seventy in the Apostolic United Brethren. Its members are distributed geographically among AUB congregations, with men ordained to this office called for life.
