Thanks Claud.
A prayer to Pio.
You're understandably concerned about phrase "pray to", because that's as high as your adoration goes--so you can't see any practical difference between adoration and veneration.
But we have the Mass. We adore God not just by prayer but by sacrifice...and if you read through the order of Mass, even those that are specifically dedicated to saints, you will not find *any* Mass offered to a saint, but always and only to God.
That's where we draw the distinction. We have this whole higher tier of adoration that the saints never enter into.
