Here is a sermon from a priest friend of mine in my native place, Fr. Thomas Dufner, pastor of Epiphany Church in Coon Rapids, MN.
He gave this sermon on 15 October 2017, just after the 100th anniversary of the final apparition of the Our Lady at Fatima.
He makes a reference to a Mass at the Cathedral of St. Paul, which was packed. You should look up the Cathedral to get a sense of the size of the crowd.
