We don't usually have a sermon on Palm Sunday. Instead you are invited to ponder carefully the connection between the Last Supper and the Sacrifice of Calvary as these events are recorded in the Passion Gospels read this week.
In many modern Churches these have been abbreviated so that the connection is not obvious. We invite you to read the text of the Traditional Masses today, and through Holy Week:
May God grant you a reflective Holy Week and a Blessed Easter!
