And you know this bit of information about her how?
This information comes to us via the
same Oral Tradition that tells us which books belong in the Bible.
If you believe that the New Testament consists of 27 books, consisting of four Gospels, fourteen general Epistles, seven Catholic epistles, and one each of the Acts of the Apostles and the Book of Revelation (also sometimes called
The Apocalypse of St. John the Divine) then you follow the
same authority who also said that Mary is without sin.
Now, if you believe that he was correct about the one thing, but incorrect about the other, you need to have an external reason - some supporting bit of evidence that shows that although he had the ability to be wrong about Mary, he (somehow) was able to be correct about the Canon of the New Testament.
Why would Paul, inspired by the Holy Spirit, write “all” (in the context of meaning all Jews and Gentiles of Adam’s fallen posterity) if both he and the Holy Spirit allegedly knew Mary was spared a “mud puddle” birth?
Because St. Paul wanted each member of his audience to understand that they themselves were not exempted from sin. “All” is a polite way of saying “You.”
You have sinned, and come short of the glory of God." Even Protestant preachers use this device, saying “All” when they mean “you” - “All” are contributing to the decline of society by going shopping on Sundays and participating in base entertainments. Obviously, not “all” do these things - but everyone in that particular preacher’s audience is doing so - but he is too polite to say “
You are contributing to the decline of society …” because he knows they will be offended to be singled out in such a way. “All” simply means “you and everyone else here” - which is easier to hear - one does not like to be singled out, after all, nor to have one’s sins announced in church.
The doctrine that Mary was spared a “mud puddle” birth is extra-biblical. Only God would have known such information about her. So who, may I ask, was personally given that bit of information; and when; and by what means?
Obviously, the Holy Spirit knew it, and gave it to the Church through the Magesterium - in
exactly the same way that He inspired the Scriptures, and permitted the Church to know which books belonged in the New Testament.
This is important because what separates the true Christian faith from all others in this world is that it is based solely on divine revelation, not on man’s imagination or speculation.
The problem comes when we mistake the
fruits of divine revelation (for example, the Bible) for the actual divine revelation itself, which comes to the Magesterium (teaching authority) of the Church from the Holy Spirit.
The Bible did not write itself, nor did it compile, translate, or publish itself. These were accomplished by human beings - the
very same human beings who taught us the things that we believe about Mary.
Again, if they were right about the one, and wrong about the other, then we need to know why and how the Holy Spirit was inspiring them, in the one case, and yet abandoned them in the other - and we need to be able to show how we know they got the Bible right, but got the teachings about Mary wrong.
