From a friend studying at Mount Saint Mary's Seminary in Emmitsburg:
I am writing to ask for prayers for the repose of the soul of Fr. David Greise. He was a graduate of Mount Saint Mary's Seminary celebrating his 25th anniversary as a priest.
Today we had our annual alumni mass here at the Mount, and during the pennitential rite of the mass, Fr. David passed out and died there while celebrating the mass. It came as a shock to us all and left many people shaken and stunned. Any prayers for the repose of his soul, his family, and those affected by the death of Fr. David would be greatly appreciated. I never knew him personally, but could tell that he was well loved and respected by his classmates, as they were shedding tears at his passing.

Wow - what a way to go!
