The Liturgy of the Holy Sepulcher has been a central liturgy for members of the Order since the earliest days of the Hospital in Jerusalem. The Order has historically admitted members from nations throughout Christendom. This included men from the various Churches of apostolic tradition. Accordingly, members of the Order have attended various apostolic liturgiesaccording to their heritages: this practice continues today. Notably, the Liturgy of Saint James, the Apostle and first Bishop of Jerusalem, has an historical use within the Order. The Liturgy of St. John Chrysostom was commonly attended by Russian members of the Order in the 19th and 20th centuries. This respect for traditional culture and life has been a practice within the Order throughout its history. While the Knights of Saint John were called to service from various nations, they were bound in their common purpose of serving and defending Christians in the Holy Land, and later Christendeom. This tradition continues in the Order today.
