Born in Jerusalem about 315, Cyril became bishop of that city probably in 349. In the course of political and ecclesiastical disputes, he was banished and restored three times. Cyril is the one we have most to thank for the development of catechetical instruction and liturgical observances during Lent and Holy Week. His Catechetical Lectures on the Christian Faith, given before Easter to candidates for baptism, were probably written sometime between 348 and 350.

The work consists of an introductory lecture, or Procatechesis, and eighteen Catecheses based upon the articles of the creed of the church in Jerusalem. All these lectures (the earliest catechetical materials surviving today) may have been used many times over by Cyril and his successors, and considerably revised in the process. They were probably part of the pre-baptismal instruction that Egeria, a pilgrim nun from western Europe, witnessed at Jerusalem in the fourth century and described with great enthusiasm in the account of her pilgrimage. Many of the faithful would also attend these instructions.

Cyril's five Mystagogical Catecheses on the Sacraments, intended for the newly baptized after Easter, are now thought to have been composed, or at least revised, by John, Cyril's successor as Bishop of Jerusalem, from 386 to 417.

It is likely that it was Cyril who instituted the observances of Palm Sunday and Holy Week during the latter years of his episcopate in Jerusalem. In doing so, he was taking practical steps to organize devotions for countless pilgrims and local inhabitants around the sacred sites. In time, as pilgrims returned to their homes from Palestine, these services were to influence the development of Holy Week observances throughout the entire church. Cyril attended the Second Ecumenical Council at Constantinople, in 381, and died in Jerusalem on March 18, 386.

Cyril's writings have greatly enriched the observance of Holy Week in the 1979 Book of Common Prayer.
