The Priesthood Is on the Earth Today.
The Church of Jesus Christ of Latter-day Saints is governed by the priesthood. The priesthood, which is always associated with God's work, "continueth in the church of God in all generations, and is without beginning of days or end of years" (D&C 84:17). It is upon the earth today. Men young and old are baptized into the Church, and when they are judged worthy they are ordained to the priesthood. They are given the authority to act for the Lord and do His work on the earth.
The priesthood is divided into two parts: the Melchizedek Priesthood and the Aaronic Priesthood.
Offices of the Aaronic Priesthood:
Deacon
Teacher
Priest
Bishop
Offices of the Melchizedek Priesthood:
