St. Cyril of Jerusalem (c. 313–386 AD) lived in Jerusalem. His theological contributions regarding the sacraments and the Creed are highly regarded in the broader Orthodox world.

Primary Works

The most significant extant works of St. Cyril of Jerusalem are his Catechetical Lectures (Katikheses). These are divided into two main sets:

1. The Procatechesis: An introductory lecture given to those beginning their preparation for Baptism (the photizomenoi or "those being enlightened").
2. The 18 Catechetical Lectures (Catecheses ad illuminandos): These were delivered during Great Lent to candidates preparing for Baptism at Pascha.

• Lectures 1–5 focus on repentance, faith, and the nature of God.
• Lectures 6–18 follow the articles of the Jerusalem Creed (which is very similar to our Nicene Creed), explaining the Trinity, the Incarnation, the Crucifixion, and the Resurrection.

1. The 5 Mystagogical Lectures (Catecheses Mystagogicae): These were delivered during Holy Week or the week following Pascha to the newly baptized (neophytes). They explain the "mysteries" or Sacraments:

• Lectures 19 & 20: Baptism
• Lecture 21: Chrismation (Confirmation)
• Lecture 22: The Eucharist (The Body and Blood of Christ)
• Lecture 23: The Liturgy and the Lord’s Prayer

1. Sermon on the Paralytic (Homilia in paralyticum juxta piscinam): A homily on the healing of the paralytic at the pool of Bethesda (John 5).
2. Letter to Emperor Constantius: A letter describing a miraculous appearance of a cross of light in the sky over Jerusalem in 351 AD.

Theological Contributions

• The Trinity and the Son: St. Cyril was a staunch defender of the Divinity of Christ. Although in his early writings he was cautious with the term homoousios (of one essence) because it had been misused by heretics like Sabellius, he remained entirely faithful to the Nicene faith, teaching that the Son is "God like to the Father in all things."
• The Real Presence: In his Mystagogical Lectures, he provides some of the clearest early Church evidence for the belief in the Real Presence of Christ in the Eucharist. He famously teaches that what appears to be bread is not bread, and what appears to be wine is not wine, but the Body and Blood of Christ.
• The Cross: In Lecture 13, he centered the entire economy of salvation on the Cross: "The Cross is the crown, not the defeat."

Historical Context

St. Cyril of Jerusalem lived during the turbulent 4th century, a time of great struggle against the Arian heresy. He was exiled three times by Arian-leaning emperors and bishops because of his commitment to the true faith.

While the Catholic Church and others claim him, we recognize his teachings as part of the consensus of the Holy Fathers before the tragic divisions of the 5th century. His emphasis on the holiness of the sacraments and the necessity of the Orthodox faith remains a pillar for all who follow the ancient path.

Coptic Reference: In our liturgy and tradition, we honor the "Three Cyrils"—St. Cyril of Alexandria (The Pillar of Faith), St. Cyril of Jerusalem, and sometimes St. Cyril of Quinis. St. Cyril of Jerusalem is remembered in the Synaxarium on the 20th of Paramhat.
