Even though Padre Pio is a saint in Heaven, we can still ask him to be our spiritual father. It was after my father died that I asked to become his spiritual child.
Dear Padre Pio, I recall your promise to the Lord, "Lord, I will stand at the gates of heaven until I see all my spiritual children have entered."The Padre Pio Foundation of America
Encouraged by your gracious promise, I ask you to accept me as a spiritual child and to intercede for my prayer requests...(Here state your petitions)
Glory be to the Father, and to the Son, and to the Holy Spirit, now and forever.
The following quotes from Padre Pio tell how he looked after and loved his spiritual family:
"I love my Spiritual Children as much as my own soul, and even more."
"Once I take a soul on, I also take on their entire family as my spiritual children."
"To my Spiritual Children, my prayers for you will never be lacking."
"If one of my spiritual children ever goes astray, I shall leave my flock and seek him out."
"I shall stand at the gates of Paradise until all my spiritual children have entered."
I often ask him to help me prior to examining my conscience and before going to Confession. I find that Padre Pio does help me in giving me spiritual direction.
