Nobody’s worshipping her, or “supplicating her deific deliverance.”. They are asking for her prayers. Just as I might ask for my own Mom to pray for me.
These are called “ intercessory prayers”. We are all very much encouraged to pray for one another, because we love one another.
The whole ensemble of loving people praying for each other is called the “Communion of Saints.”
She can’t hear you. She was just a human, just like you.
Only Jesus can intercede.
