When Mary gave birth to Jesus he was not a God. He was a little human baby.
'Blessed [art] thou among women, and blessed [is] the fruit of thy womb.
The above is indeed the correct translation. No where in scripture is Mary ever called "Most Blessed" as your original post suggested....she is called "Blessed".
Only one time in scripture is any woman called "Most Blessed"....or "Blessed" above women....and that is "Jael" in [Judges 5:24].
***When Mary gave birth to Jesus he was not a God. He was a little human baby.***
Do you believe that Jesus is the Second Person of the Trinity? If so, He is God. If Mary is His mother, she is the mother of God (the second person of the Trinity). It is really quite simple.
Now, if you DON'T believe that Jesus is the Second Person of the Trinity, then you believe in Nestorianism, a heresy that claims that Jesus was just a human man and not God. This heresy was rebutted at the Council of Ephesus in 431 A.D. with the doctrine that Mary is "Theotokos," the "God-bearer." This description of Mary is really all about Jesus, because it defines His nature and who He is.
