If you're not when he asks you, than you're right, it's not worship, rather its a typical sign of delusional psychosis.
In English it's not been since the 1600s that the phrase "I pray thee" was used to ask for something. The issue is not respect for great saints, or the humility to ask others to pray for you--something I do routinely to my brothers who are alive. Do you?
But you and I, like the homeless man, cannot ask someone something if they are not there, and cannot hear us.
God alone is omniscient; neither Mary, nor any of the other saints in Heaven are--and I challenge you to show me where in holy Scripture citizenship in heaven for humans implies gaining God's omniscience or omnipresence.
There is no difference between humbly begging your brother who is alive on earth to pray for you than there is humbly begging St. Peter, St. Paul, St. Andrew, St. Therese, or St. Bernadette, all of whom are alive in Heaven, to pray for you.
Ummm, just WHY is that, just because you assert it? Please prove to me that the saints in heaven can hear us, just like the saints we speak to on earth can.
And please notice I have not given one word of insult to you in return to the insulting manner you addressed me.
