'How is it that a Bishop comes between the Twelve Apostles and the Seventy Apostles, and can cut off an Apostle but an Apostle of the Seventies cannot cut off one of their Quorum;'Br Joseph Young Senr. replied that it was true that the decision of a full Quorum of Seventies, acting unanimously was equal to the Quorum of the Twelve. It is also true and that he had never known that when a man was cut off from the Church that it was ever done by the Seventies, but they could disfellowship them from their Quorum. He referred to the case of Theodore Turley who fell into transgression. The prophet told him to throw him out of his Quorum; having at that time a delicacy the Prophet said he would take him to the High Council. He said that the Seventies are under the jurisdiction of the Bishops. They take their Tithing and Offerings to the Bishops. They do not handle the Seventies except for misconduct. The Presidents of the Stakes have called upon the Seventies as Home Missionaries and they are generally satisfied with the kind treatment they receive from the Bishops. Many have to be sent on Missions and are generally ordained Seventies. Speaking of his own experience he said that he never knew that he was President of the Seventies until he came to Nauvoo and Br Brigham told him that that was his place and he took it. During the reformation he had surrendered his Presidency to Br Brigham and he did not take it.
