John II (Greek: Ἰωάννης Β΄; c. 356 – 10 January 417) was bishop of Jerusalem from AD 387 to AD 417. John II succeeded to the episcopal throne of Jerusalem on the death of Cyril in 386 (or 387). He was the author, according to an increasing number of modern scholars,[1] of the five Mystagogical Catecheses traditionally ascribed to his predecessor Cyril.
He is revered as a saint by the Eastern Orthodox Church and his feast day is held on March 30.[2][3][4] He is also honored as a saint by the Roman Catholic Church, which commemorates him on 10 January (Martyrologium Romanum, 2004, p. 92).
