Mary is the mother of Sam. Sam is a fireman. Therefore, Mary is the mother of firemen. Get it?
The title "mother of God" means that Mary is the mother of God the Son, the Word, the Second Person of the Trinity, because she conceived him in her womb and bore him. It has NEVER meant that Mary is the mother of God the Father and/or God the Holy Spirit.
In other words, you are arguing against an assertion that NO ONE HAS EVER MADE--namely, that Mary is the mother of the Trinity or the mother of one or both of the other Persons of the Trinity.
If one hears mother of God how does one know it is limited to only Christ? Why would the term not apply to the Father and Holy Spirit?
I’m not arguing against an assertion “nobody has made” but against the illogic of your syllogism.
On the contrary, that is EXACTLY what *mother of God* SAYS.
You all can deny it and claim that it means something different than what it says, but then you are denying the plain basic reading of a simple statement.
If it actually MEANS something different, then whoever chose that term did a poor job and it needs to be reworded to more accurately say what it means.
Kind of like what the HOLY SPIRIT did when HE chose to use the term *mother of Jesus*.
God was not conceived in the flesh...God was planted there, by the Holy Spirit...
