this list only includes individuals who have served in the quorum. this list is organized by current quorum members, original quorum members, then by date of appointment to the quorum, and then by last name. members of the first presidency, which include the president of the church and his counselors, are usually not part of the quorum, and a calling to the first presidency usually entails leaving the quorum. exceptions to this rule are noted. it is also possible to be ordained to the priesthood office of apostle without automatic membership in the quorum of the twelve, or to serve in the first presidency without having been ordained an apostle. such individuals who never became members of the quorum do not appear in the last section of this page.
