Two years ago I interviewed various elderly nuns who had known Padre Pio, and who had received spiritual counsel from Padre Pio. One nun was a mother superior, and Padre Pio had told her that she had a vocation to be a nun. The nuns explained to me that St. Pio held St. Philomena in great esteem, and never doubted her intercessory powers. During his lifetime Padre Pio said to an Irish lady, Mary Philomena Mulcahy, "Saint Philomena is in Paradise, the confusion is the work of Satan."
The Curé of Ars used to bless cords of St Philomena, and gave them as gifts. He also composed the following litany to her.
PS - Happy Feastday of St. Philomena to one and all!
