Teachers are organized into quorums of twenty-four each. The duty of those bearing this office is to see that the Saints do their duty and entertain no ill-feelings toward their fellow-beings, and that no iniquity exists in the Church. These general duties, common to all Saints, consist in living a chaste, honest, upright, temperate and industrious life, attending to secret and family prayers, attendance at meetings of worship, partaking of the sacrament, the payment of tithes and offerings, observing the Sabbath day, and kindred obligations, all made plain in the revelations of God to the Church. The Deacons are organized into quorums of twelve each, and are to assist the Teacher in all the duties of his calling, as occasion may require, but their especial duty is to look after the houses of worship, keep them clean, see to the arrangement of seats and the seating of the people in public assemblies of worship, and such other labors under the direction of the Bishop as may conduce to the welfare of the Church. The Melchisedek or higher priesthood holds the keys to the kingdom of heaven. It has the power to seal on earth, and what is done is sealed in heaven; to loose on earth and it is loosed in heaven; to receive the revelations of God; to guide the Church in all things, and to understand the mysteries of godliness as far as they are revealed to men in the flesh. In ancient times these keys and fullness of authority were given to Peter when the Savior said to him: "And I give unto thee the keys of the kingdom of heaven." (Matt. xvi:19.) The offices of this priesthood consist of the First Presidency, a quorum of three, bearing the holy apostleship, and as the organization of the Church on earth typifies the heavenly, these three symbolize the Father, Son and Holy Ghost, and hold the keys of authority over all departments of the Church, on all matters, spiritual and temporal, even as the Godhead is the great ruling power of the universe, the heavens and the earth and all that in them is. Next come the Twelve Apostles, who hold the keys of opening the door of salvation to all nations, kindreds, tongues and peoples. The reason that this quorum numbers twelve is in honor of the twelve tribes of Israel. Jesus said to the Twelve at Jerusalem: "Thou shalt sit upon twelve thrones, judging the whole house of Israel;" and again, upon the foundations of the heavenly Jerusalem were to be the names of the "Twelve Apostles of the Lamb." The Church in government is "built upon the foundation of the apostles and prophets, Jesus Christ Himself being the chief corner stone." (Eph. ii:19, 20.) The duty of the Twelve is to carry the Gospel to all nations and to send the same by their associates, the Seventies.
