Some men join the Church or become active after they have passed the usual age to receive the offices of this priesthood. They are usually ordained to an office in the Aaronic Priesthood and can soon be advanced to higher offices if they are worthy. A boy who has been baptized and confirmed a member of the Church and is worthy may be ordained to the office of deacon when he is twelve years old. The deacons are usually assigned to pass the sacrament to members of the Church, act as ushers, keep Church buildings and grounds in good order, act as messengers for priesthood leaders, and fulfill special assignments such as collecting fast offerings. A worthy boy may be ordained a teacher when he is fourteen years old or older.
Teachers have all the duties, rights, and powers of the office of deacon plus additional ones.
To help fulfill this responsibility, they are usually called as home teachers. They visit the homes of Church members and encourage them to live the principles of the gospel. Teachers also prepare the bread and water for the sacrament service. A worthy boy may be ordained a priest when he is sixteen years old or older. A priest may baptize.
