Administratively, there are numerous presidents within the Church, including congregational presidents (pastors), presidents of large jurisdictions of the Church (mission centers), presidents of local priesthood quorums (any quorum of deacons, any quorum of elders, etc.), and presidents of World Church level priesthood quorums (Council of Twelve Apostles, Quorum of High Priests, etc.). However, only members of the highest body of the Church, the Quorum of the First Presidency, are actually "ordained" to the "priesthood office" of President. All three members of the First Presidency are thus termed “President X, President Y, President Z”. However, only one of these individuals is the actual president "of" the Church (and of the quorum itself). To put it simply, all three are presidents by priesthood office, but only one is the administrative and spiritual President "of" the Church. The other two serve as his or her counselors, and are often informally referred to as such.
