Contrary to most descriptions, a Roman scourging was a vicious affair. It usually killed a person at forty lashes or greater because of blood loss from exposed internal organs. The entire purpose of a public lashing is to scare away people from either supporting the victim's cause or preventing certain crimes. It should come as no surprise there were very few of Jesus public supporters and apostles at the foot of his cross when he died. That was the entire idea behind a cruxifixction.
So approaching the Shrine, on the southern portico we have this cross at the end. With a single kneeler just begging you to come and pray with and for our Lord in his suffering. A suffering which continues today in this world. Jesus' persecution continues today with attacks on the people of his church around the world. Jesus' church on this earth needs our prayers as much now as ever!
So the lonely kneeler begs the question from Jesus: Will you pray for me?
