Holy Week is the greatest week of the liturgical year. Devotion to Christ's passion is essential for salvation. The paschal mystery describes the law of dying and rising that must direct our lives. The more deeply we enter into this paschal mystery, the more we will experience victory over sin. The more we enter into the love of Christ that powered Him through His passion, the more we move into a love that crowds out sin. That is the power of the cross of Christ.
