who is Immanuel, interpreted by the Holy Spirit as "God with us." Mary is the mother of Immanuel. Mary is the mother of "God with us."
What I wrote above is what the Holy Spirit inspired.
No "personal savior" is there for you to use.
Frankly, any other title given ... would be going beyond what God revealed to us.
It would then be hypocrisy to go beyond "my saviour," or "saviour of the world."
This is where your argument goes off the rails as I already commented on the use of ‘personal.’
There is absolutely no correlation between explaining the literal use of Scriptural terms and then expressions which come from them. For we see the expressions in the words used.
How you correlated the above with inferring Mary as ‘mother of God’ amazes me.
However, I’ll bite...By your inference and use of Immanuel are you comfortable giving Mary the title of “Mother of YHWH”?
