For us laypeople, Holy Week is a glorious time of great excitement. I look forward to it every year. For our priests who make it all happen, it is also glorious and exciting, but their ability to enjoy it as such is limited. Multi-hour Confessions almost daily, new members of the Church, and preparing for festivities and special liturgies, while beautiful privileges they cherish, also form a very heavy, stressful, and sometimes agonizing cross. These consecrated men of God truly lay down their lives for the sheep. I spend every Holy Week in prayer and fasting for them, and find my own Holy Week experience nourished as a result. Out of love, gratitude, compassion, and reverence for their holy gift of self for us, let us relieve them as much as possible through prayer and sacrifice.
