Oaks. Following the death of Boyd K. Packer on July 3, 2015, Nelson became the most senior member of the Quorum of the Twelve and the quorum's president. Nelson was set apart as the quorum president on July 15, 2015, by Thomas S. Monson. Nelson made his first international trip as quorum president to Central America from August 20–31, 2015. The following month, Nelson dedicated the renovated Aaronic Priesthood Restoration Site in Pennsylvania, where LDS Church members believe the Aaronic and Melchizedek priesthoods were restored.
