In Holy Week, the faithful join themselves to Christ in His suffering, death and resurrection. The Christian life is not something we do for God, but, rather, something God does in us.
Just as we share in Christ's Body and Blood in the Eucharist, so we share in His life-giving passion in the services of Holy Week. St. Paul prayed that he might know the "communion of Christ's sufferings, and the power of His resurrection" (Phil.3:10). This is a summary of the Christian life, a summary that is expressed as liturgy in the services of Holy Week.
