In the unlikely event that the First Presidency and Quorum of the Twelve all died simultaneously, how would that affect succession? In this hypothetical worst-case scenario, would the keys of the kingdom be lost? And, if an apostle came down with a debilitating health problem, is there any precedent for making him an emeritus apostle?  And speaking of apostles, is there a set procedure in calling them, or does the method vary from Church president to president? Also, sometimes in the Church people speak of a special requirement for a man to become an apostle—the phrase “sure” or “special” witness of Christ comes up a lot. What’s true? Must a man have personally seen Jesus Christ in order to be fully considered an apostle? On this episode of Church History Matters Casey and I are joined by a special guest, Dr. Daniel C. Peterson, to help us answer these and other great questions related to succession.  For show notes and transcript for this and other episodes go to https://doctrineandcovenantscentral.org/church-history-matters-podcast/
