5. _The Twelve:_ "The twelve traveling counselors are called to be the Twelve Apostles, or special witnesses of the name of Christ in all the world; thus differing from other officers in the Church in the duties of their calling. * * * * The Twelve are a traveling presiding High Council, to officiate in the name of the Lord, under the direction of the Presidency of the Church, agreeable to the institution of heaven; to build up the Church, and regulate all the affairs of the same in all nations; first unto the Gentiles, and secondly unto the Jews. * * * * The Twelve being sent out, holding the keys to open the door by the proclamation of the gospel of Jesus Christ--and first unto the Gentiles and then unto the Jews." (Doc & Cov., Sec. cvii.) This is the special calling of the Twelve Apostles, and the calling of the Seventy is like unto it. 6. _The Seventy:_ "The Seventy are also called to preach the gospel, and to be especial witnesses unto the Gentiles and in all the world. Thus differing from other officers in the Church in the duties of their calling. * * * * The Seventy are to act in the name of the Lord, under the direction of the Twelve or the traveling High Council, in building up the Church and regulating all the affairs of the same in all nations--first unto the Gentiles and then to the Jews. * * * * It is the duty of the traveling High Council to call upon the Seventy, when they need assistance, to fill the several calls for preaching and administering the gospel, instead of any others. * * * * And these Seventy (the reference is to the whole body of that Priesthood) are to be traveling ministers unto the Gentiles first, and also unto the Jews. * * * * Whereas other officers of the Church, who belong not unto the Twelve, neither to the Seventy, are not under the responsibility to travel among all nations, but are to travel as their circumstances shall allow, notwithstanding they may hold as high and responsible offices in the Church." (Doc. & Cov., Sec. cvii.) When the Church was set in order at Nauvoo, in 1841, by direction of a revelation (Doc. & Cov.; Sec. cxxiv.) after naming the First Seven Presidents, who were to preside over the quorums of Seventies, the Lord said: "Which quorum is instituted for traveling Elders to bear record of my name in all the world, whenever the traveling High Council, my Apostles, shall send them to prepare a way before my face. The difference between this quorum and the quorum of Elders is, that one is to travel continually, and the other is to preside over the churches from time to time: the one has the responsibility of presiding from time to time, and the other has no responsibility of presiding, saith the Lord your God."
