Ecumenical Commemoration
Bishop & Doctor of the Church
March 18 · d. 386
also known as Cyril of Jerusalem, Cyril of the Holy City
Cyril of Jerusalem is remembered primarily for his Catechetical Lectures, a systematic instruction given to catechumens (those preparing for baptism) that provides the most detailed early source for 4th-century liturgical practice and Christian doctrine. Though he faced exile multiple times for his opposition to heresy and for ecclesiastical disputes, his pastoral and catechetical work shaped Christian initiation for centuries.
Traditionally, Cyril's three exiles were understood as the cost of his faithful witness to orthodoxy. Socrates reports that during one exile, Cyril's opponents spread false charges against him and attempted to undermine his reputation, but that his integrity and the truth of his teaching eventually vindicated him. Later hagiographic sources attribute miracles to Cyril — including healings and visions — but these are not found in the earliest sources.
Cyril's role as custodian of the liturgy of Jerusalem, the city of Christ's redemptive work, gave him special significance in Christian tradition. His catechetical method — careful instruction in the creeds, the sacraments, and Christian virtue — became the model for Christian initiation across the Church.
Cyril was born around 313 in Jerusalem. Little is known of his early life, but he emerged as a prominent figure in the Jerusalem church during the episcopacy of Macarius (314–335), the bishop who presided over the dedication of the Church of the Holy Sepulchre under Constantine. Cyril was ordained a deacon under Macarius and later became known as a powerful preacher and catechist.
Around 349, Cyril was ordained as bishop of Jerusalem — though the exact date is disputed. He inherited a church that was experiencing rapid growth due to Constantine's building of the Holy Sepulchre basilica, which made Jerusalem a major pilgrimage site. Cyril's role included not only governing the Jerusalem church but also caring for the influx of pilgrims and instructing the growing numbers of catechumens seeking baptism.
It was probably between 350 and 365 that Cyril delivered his most famous work: twenty-four lectures given to catechumens in preparation for their baptism at Easter and Pentecost. These Catechetical Lectures (preserved in the tradition of Cyril's works, though some scholars dispute the attribution of a few lectures) provide the most comprehensive surviving account of 4th-century liturgical practice, including the structure of the Eucharistic prayer (anaphora), the practice of the sign of the cross, the veneration of the cross, and practices of Christian discipline and penance.
Cyril's episcopacy was not without conflict. Like many bishops in the fourth century, he became embroiled in ecclesiastical disputes related to Arianism and imperial politics. He was exiled at least three times: first by the Arian bishop Acacius of Caesarea (around 357), then by the Emperor Valens (around 367), and finally by the Emperor Theodosius's ecclesiastical appointees (around 384). However, unlike some bishops whose careers were entirely defined by these conflicts, Cyril maintained his primary focus on pastoral work and catechesis.
During the reign of the orthodox Emperor Theodosius (379–395), Cyril was restored to his see and spent his final years in pastoral work. He died in 386, having served the Jerusalem church for nearly four decades. His catechetical lectures ensured that his name would be preserved and venerated by all subsequent generations as a model of systematic Christian instruction.
Almighty God, you gave your servant Cyril of Jerusalem special gifts of grace to understand and teach the truth revealed in Christ Jesus: Grant that by this teaching we may know you, the one true God, and Jesus Christ whom you have sent; who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
