Synonymous, maybe. The same, no. The man's quote was taken out of context, purposely, distorting what he was trying to say. You very well know he was not trying to say that Jesus was not Mary's son.
I wasn't talking about what MacArthur said, rather I was talking about the historic and orthodox Christology itself.
To say "Mary is the mother of God" is identical with saying "The Child which Mary gave birth to is God". Those are identical statements and have the same meaning.
Both speak of the Child Mary had, Jesus. These are Christological statements.
So when someone says that Mary is not the mother of God, they are denying that the Child Mary bore is God.
This isn't a Protestant vs Catholic thing. Which is how so many contemporary Protestants imagine it. This is a matter of good Christology on the one hand, and bad Christology on the other.
I'm not going to accuse John MacArthur of heresy, because I don't know if he is speaking out of his own personal ignorance, or if he is attempting to undermine the foundational doctrines of the Incarnation. But I think it fair to give him the benefit of the doubt that he is simply ignorant.
The reason for this modern problem isn't, I don't think, because of heresy; but ignorance, it is the all too prevalent problem of theological illiteracy among Christians.
People take issue with this for the same reason people frequently get the doctrine of the Trinity completely wrong.
Saying "Mary isn't the mother of God" is like when I see people argue against the Eternal Generation of the Son. They are ignorant, they have not been taught basic Christian doctrine in such a way that they understand what it is that we confess and believe as Christians.
So the point of my post wasn't to address MacArthur directly, or even indirectly; but rather to give defense of basic Christian doctrine.
To say that Mary is the mother of God is synonymous with saying the Child which Mary bore is God. These statements are identical in meaning.
Understanding that is key to healing this particular theological confusion.
