The Christian liturgical year follows the life of Jesus, with church services moving from the predictions of his coming in Advent through to his death at Easter. The annual pattern of this re-enactment gives structure to the worship, and therefore to life itself. Although it is a cycle, repeated each year, St Augustine suggested that, unlike nature's cycles, Christian time was continually moving forward towards the second coming of Christ. Easter is seen as the most important of all Christian festivals, culminating with the observance of Jesus' crucifixion and death on Good Friday and his resurrection on Easter Day.
