I have asked saints to pray for me, if that is what you mean.
Right at the end of the Ave Maria I do it every time I sing it, which is just about every day:
Holy Mary, mother of God, pray for us sinners now and at the hour of our death. Amen.
Or, since I am singing it: "Sancta Maria, ora pro nobis peccatoribus nunc et in hora mortis nostrae. Amen."
Now, what I think I am doing is asking a holy lady to pray FOR me TO God, like I might ask you to pray FOR me TO God.
If I ask you to pray for me, or ask her to pray for me, as far as I know I am not worshipping either one of you.
You seem to know otherwise.
Enlighten me.
So, are saints demigods in your religion? They play some minor role before you get to the big league. Seems like polytheism to me.
