Aaronic Priesthood
- The lesser or preparatory priesthood, whose offices are Deacon, Teacher, Priest, and Bishop; typically conferred on worthy young men beginning in January of the year they turn 12.
Named after Aaron of the Old Testament, the Aaronic Priesthood administers the outward ordinances of the gospel — most visibly the sacrament and baptism — and prepares its holders for the higher Melchizedek Priesthood.
