I'm surprised this thread is so focused on Mary instead of how wrong it is to make an object of veneration out of Paul's tomb.
"I'm surprised this thread is so focused on Mary..."
The Mary focus was brought in after the thread was hijacked.
"... how wrong it is to make an object of veneration of Paul's tomb."
If you wish to believe that it is wrong to venerate the relics of St. Paul that is your prerogative.
Hundreds of millions of Catholic, Orthodox, Coptic, and Protestant Christians, however, do not likely agree with you on this point.
