In the evening, the All-Night Vigil for the Feast of the Nativity is composed of Great Compline, Matins and the First Hour. The Byzantine services of Christmas Eve are intentionally parallel to those of Good Friday, illustrating the theological point that the purpose of the Incarnation was to make possible the Crucifixion and Resurrection. This is illustrated in Eastern icons of the Nativity, on which the Christ Child is wrapped in swaddling clothes reminiscent of his burial wrappings. The child is also shown lying on a stone, representing the Tomb of Christ, rather than a manger. The Cave of the Nativity is also a reminder of the cave in which Jesus was buried.
