I do not believe it is any more extrascriptural than saying the flesh of Jesus was all hers.
If there had been some man's DNA mixed in, then that would have given Jesus at least a virtual human father.
Not if there was never a human male with that DNA.
At any rate, I don't think Al is making a biogenetical point here
Perhaps, but it seemed to me that he was since he said the flesh of Jesus was her flesh.
pleased God to have a human mother, when He could have incarnated in some way that would avoid a human mother just like He was born without a human father.
Yes, God could have done that if He chose to do so. But instead, He chooses to work through the human beings, usually the ones thought by the world to be least likely to draw God's attention.
I believe that Mary deserves great honor, just as I honor all the great servants of God. We just need to be careful not to elevate her above the level of human being.
The scripture mentions human mother of Christ, and God the Father. Looks like Al’s view is pure scripture, not yours.
It is true that Mary is not the only human instrument that God chose; the entire Church is such instrument as well. Nevertheless she stands out, for obvious reasons.
