St. Cyril of Jerusalem, a Church father; born in or near Jerusalem, Palestine, about 315. He was elected bishop of his native city in 351. He was engaged in hot conflict with his metropolitans, the Arian bishop Acacius of Caesarea, who caused him to be twice deposed. He was for the second time restored to his episcopate in 383. Soon after, his old enemy Acacius died, but Cyril was involved in new difficulties. After considerable strife Cyril was banished by order of the Emperor Valens in 367; nor did he return till the emperor's death in 378. He died in 386.
