It is no 'falsehood' to SHOW what the BIBLE actually says: "Mother of Jesus".
WHY Rome wants to ESCALATE that up to mother of GOD is beyond me.
Unless; it is to ESTABLISH the supposedly SINLESS nature of Mary.
A sinful mother could have given birth to a god that has come in the flesh;
but only a sinLESS mother could give birth to a GOD in the flesh.
I'm not sure where you got this. This is not my doctrine. IS it yours?
