Imagine what Paul would have specifically said had he known people would have PRAYED TO him when he had departed this earth. Or had asked for his intercession with God with Christ reigning. The Epistle to the Catholics.
Please read the prayer again. We are asking St. Paul to pray for us. (intercede for us )(intercession)
Read the introductions to his Letters. In almost everyone of them he prays for them....and then again at the end of the letter.
"In the day when God shall judge the secrets of men by Jesus Christ according to my gospel." (Rom. 2:16).
This is what will be presented to you, Salvation. NOT copies of your 'prayers' to St. Paul.
