From the Assumption Grotto homepage:
Fr. Hardon spent much time in his final years at Assumption Grotto. I happened to be there with my camera the day that Msgr. Eugene Morris(then Fr. Morris) made the trip to the parish to move his library back to St. Louis, Missouri, where his case is being studied.Fr. Robert McDermott, Postulator for the Cause of Beatification and Canonization of the Servant of God, Fr. John A. Hardon S.J., will be the Homilist at a Mermorial Mass celebrated by Fr. Eduard Perrone on June 18th at 7:00 p.m. at Assumption Grotto Church. A Marian Catechist meeting will be held after Mass in the school lounge. Everyone is invited. [this ought to be interesting]
There is a webpage dedicated to the cause of Fr. John Hardon, SJ.
There was also a nice article in National Catholic Register print edition (Sept 2006) that I was authorized to republish enttitled: "St. John Hardon?", which gives some interesting details of his life.
Please come if you are available for this special evening at Assumption Grotto.
The obedient are not held captive by Holy Mother Church; it is the disobedient who are held captive by the world!
