Cyril, the anti-Arianist bishop of Jerusalem, has written twenty-four treatises on Christian doctrine called Catecheses.

Acacius, the Arian bishop of Caesarea, had had exiled Cyril from his see in 358, forcing his retirement to Tarsus; the Council of Seleukeia, held two years later, results in his reinstatement and the deposition of Acacius.

The process in 360 had been reversed through the metropolitan's court influence, and Cyril had suffered another year's exile from Jerusalem, until the accession of Julian the Apostate allows him to return in 363.
