On Holy Thursday, I think it is important to reflect on an oft-missed detail that has tremendous applications. Jesus sent the two disciples, Peter and John, into the city to prepare for the feast by telling that they would meet a man carrying a water jar. They were to follow him, and, entering the house which he entered, tell the head of the house that the Master was to have the Passover there with His disciples. This man would show them a large upper room, fully furnished, and there they were to prepare the meal.
Why Jesus used such a cryptic way of pointing out the house was to keep Judas unaware of the place, for Jesus knew that the traitor was looking for an opportune time to have Jesus arrested, and the Lord did not want the Last Supper to be interrupted by the temple guards.
It is also evident that Jesus knew this man who owned the house, and had arranged something in advance, even if it was simply that this unknown man was a hidden disciple, or at least a friend of Jesus.
This man had the privilege of having the First Mass, the First appearance to the apostles of the Risen Lord, and Pentecost in his home. Some traditions say he was the father of John Mark, of Gospel fame, but the Gospels themselves are silent on the matter. Whatever the case, his simple friendship of Jesus and the welcoming attitude of this man gave him a grace of unimaginable joy. His family shared this joy and they were among the first Christians to be sure.
The opportunity is not lost to history, for Christ seeks friendship with all. A welcoming home is among His greatest joys.
