If I ask you to do something that only God can do, that is worship. If I ask you to save me from Hell, or to give me grace or to give me peace in my heart, then that is worship.
Only the uninformed or the heretical ask Mary to save them from Hell.
Hail Mary,
Full of Grace,
The Lord is with thee.
Blessed art thou among women,
and blessed is the fruit
of thy womb, Jesus.
Holy Mary,
Mother of God,
pray for us sinners now,
and at the hour of death.
Amen.
If we worshiped Mary, we wouldn’t be asking her to pray for us, would we? We don’t ask Jesus to pray for us, since He is God. If we believe that Mary is God, or an equivalent of God, then who would she praying to?
