Prayers that God will forgive him.
We need as many good priests as we can get, and he seems to have been a good priest.
Hard to imagine why he would do something like this, but I hope that he was not in his right mind, that he repented at the last instant, and that God will forgive him.
It is a terrible thing for a priest to commit suicide! I pray that he has been saved through the grace of Our Lord.
His judgment could have been severely diminished by the psychiatric medications he was taking. There is voluminous evidence that some of these drugs can cause suicidal thoughts and feelings.
His soul has been commended now to the infinite Mercy of a loving God. That is all we really know.
