[Desdemona]

She carried an incarnate Christ, who was God and man. Not ALL of God's essence.

How is it possible for Christ to be God and not have all of God's essence?

She could not bear God because, simply put, you cannot get all of GOD in a womb or an other earthly vessel.

Why not? God can be anywhere God wants to be. All things are possible with God. (that statement is in the bible)

[Praxeus]

"How is it possible for Christ to be God and not have all of God's essence?"

I'll give you Phillipians 2:6-7 to answer:

7 but emptied himself, taking the form of a slave, being born in human likeness. And being found in human form,
8 he humbled himself and became obedient to the point of death-- even death on a cross. - (NSRV)

So it was an "emptied" (vs 7 NSRV) essence of God in Christ. It was impossible for ALL of God to be limited to a human form, Jesus was not limited to the earthly body. He was in heaven at the same time he was on earth:

And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven. - (John 3:13 KJV)

The incarnation was a limiting of God's presence to a human body. This is what Mary bore. To say she bore God in any fashion other than derivatively is not accurate.
