The leadership structure of The Church of Jesus Christ of Latter-day Saints begins with a man who has been sustained by Church membership as a living prophet. This man has two counselors to assist him. The three men together comprise what is called the First Presidency.
The First Presidency is at the top of the Church's leadership chain. Next in line are the Twelve Apostles. These twelve men, in addition to the three men of the First Presidency, are all considered within the LDS Church to be "prophets, seers and revelators."
Following the Prophet and Apostles are many additional Church leadership offices. Except for offices relating specifically to women and children (Relief Society, Primary, and Young Women), these positions are filled exclusively by men. Below is a simplified diagram of the leadership structure of the Mormon Church.
