Pope John II

Pope John II (Latin: Ioannes II; c. 475 – 8 May 535), born Mercurius, was the Bishop of Rome from 2 January 533 to his death on 8 May 535. As a priest at St. Clement's Basilica, he endowed that church with gifts and commissioned stone carvings for it. Mercurius became the first pope to adopt a new papal name upon his elevation to the office. During his pontificate, John II notably removed Bishop Contumeliosus of Riez from his office, convened a council on the readmission of Arian clergy, and approved an edict of emperor Justinian, promulgating doctrine opposed by his predecessor, Pope Hormisdas.
