The Way of the Cross is a devotional service that is frequently observed during Lent. There are 14 stations in most churches - each with either a picture or bas-relief depiction. Many services add a 15th (the Resurrection) at the Altar. After a brief introductory prayer the Deacon or Priest, often attended by a Cross Bearer, will then stop at each station in order for a short prayer and response noting the exact station depicted - there is usually a small pamplet available for you to follow along.
At the end there is a final prayer. Many parishes - such as ours - combine the Way of the Cross with the Exposition and Benediction of the Holy Eucharist.
Most Way of the Cross services in my experience last less than 1/2 hour. The Exposition and Benediction can add 15-20 minutes.
It is a wonderful and very prayerful way to meditate on Christ’s supreme sacrifice for us as we prepare for Easter.
