In 1835, the Lord gave the revelation
on this matter that provides for orderly succession.
The revelation states that the Quorum of the Twelve Apostles
is a body equal in authority to the First Presidency.
That means that when the President of the Church dies,
the First Presidency is dissolved,
and the Quorum of the Twelve automatically
become the presiding body of the Church.
That pattern was established with the death of the Church's
first President Joseph Smith.
This divinely revealed procedure for installing a new First
Presidents of the Church, revelation from the Lord,
and sustaining by the people has been
followed to our present day.
The First Presidency is to be upheld by the confidence,
faith, and prayer of the Church.
