VATICAN CITY (AP) — Pope Francis has formally named Monsignor Michael Byrnes as Guam's archbishop following the definitive sex abuse verdict against his predecessor.

Byrnes in 2016 had been named coadjutor bishop for the U.S. Pacific island territory, giving him the right of succession after Archbishop Anthony Apuron was removed pending the investigation into claims by former altar boys that he assaulted them. On Saturday, the Vatican made that transition official after Apuron's guilty verdict was upheld on appeal.

His sentence — a lifelong ban from Guam, removal from office and prohibition of presenting himself as a bishop — disappointed victims' advocates since he was allowed to stay in ministry and not defrocked.

Byrnes has called the sentence "a monumental marker in our journey toward healing."
