Is this the Fr. John O’Connor in southern Indiana?
He has Fr. Gavin Bitzer from OL of the Pillar in Louisville, KY say Mass at his chapel certain Sundays and weekdays.
As of this October, he’s alive and kicking in his 90’s!
I don’t know when he was ordained or by whom, but given his age and the fact that Fr. Bitzer works with him, I’d have no concern about going to Mass at his chapel.
