I think the key here is 'worship', to worship a saint is to give what is rightly God's to another.
As Revelation 22 says:
I, John, am the one who heard and saw these things. When I heard and saw them, I fell down to worship at the feet of the angel who had shown them to me. But he said to me, Dont do that! Im a servant just like you and your brothers and sisters, the prophets, and those who keep the words of this scroll. Worship God!
The key is her ignorance.
