The Passion, Death and Resurrection of Jesus occurred over the feast of Passover, a time when there were many pilgrims who had made the journey to Jerusalem and the Temple, yet it was the entry of Jesus that was hailed triumphantly with crowds waving palm branches, and it was his presence in the city that attracted the attention and the ire of the Sanhedrin. After the death and Resurrection of Jesus, several of the apostles like Saint Paul and his followers spread the Christian faith further and further from the Holy Land, and the people were inspired to return to the holy sites to walk the Way of the Cross.
One of the earliest usages of the word is found in the writings of Saint Augustine of Hippo (354-430). His work, Peregrinatio, described a Christian spiritual journey as a search for God's truth by visiting the holy shrines of the Faith. In the Middle Ages it became a common religious practice to make a pilgrimage to a holy shrine and venerate the relics of saints. Even in modern times pilgrimages are made to holy sites.
