And so when the antagonists of orthodox Christianity use Exodus 20:4-5 against Mary and the other followers of Jesus, they are using it out of context. Mary is not another god!
She is the Mother of God (Jesus) and she says of herself, My soul magnifies the Lord, and my spirit rejoices in God my Savior (Lk 1:46-47). Pagan gods do not magnify the Lord; however, Jesus' Mother Mary does magnify Him. The adversaries of Mary and her role in the Gospels are making Mary into a god. They have in effect made her an enemy of Jesus by using a verse of the Bible that has to do with Pagan gods and applying it to Mary. What’s the harm in this? When some Evangelicals see that their tradition is embracing this type of intellectual dishonesty, some leave Christianity altogether. Still, there are many wonderful Evangelicals out there, who after seeing the Bible taken out of context by their tradition, have made their journey home to the Catholic Church.
