Reader Scottie has forwarded me this response he received via email from one Pope Michael, no affiliation with the original monks emailed. We are pleased to receive critique and feedback on our posts here. It is a bit late now, and the points raised in this response require deeper evaluation. For now, I will simply post it here. Please feel free to comment on this or the original post.
Dear Scottie,
This one is interesting. First of all, four people were born without Original Sin. Jesus, being God did not have Original Sin, obviously. Secondly, the Blessed Virgin Mary was conceived without original Sin as a special privilege from God. However, she did have to cooperate with these graces, and objectively speaking could have sinned. What if she had said no to the Angel at the Annunciation? Mary cooperated most perfectly with Almighty God in her salvation. She simply got a benefit most of us do not have, which God may do. Two others were born without Original Sin. Saint John the Baptist was purified at the time of the Visitation, and thus born without Original Sin. For this reason we celebrate the Birthdays of Jesus, Mary and John the Baptist and no other Birthdays in the Church. I believe the Prophet Jeremias was also sanctified in this manner.
We all must cooperate with God in our salvation, because God will not save us without our cooperation. This would deny free will, as the Calvinists apparently do. I wish I had a copy of the special I saw on the History Channel about two years ago on how Protestant thought has influenced the modern world. Calvin’s doctrine of justification had some surprising results. He taught that we were either saved or not no matter what we do. One group, and I forget the name, that spun off from this sinned like mad, because it simply does not matter under Calvinism. This reaction is logical and dangerous and proves the falsehood of the the Calvinistic proposition of justification. Remember also that Adam and Eve were not conceived in sin, but they sinned anyway, so being free from Original Sin is not a guarantee of salvation.
Yes it is well written, but it is what they do not say.
I hope this helps.
High School Apologetics 
I believe this post brings up an even deeper question regarding the ramifications of Mary’s birth without original sin. This post does nothing to squash the idea that Mary had free will in the first place. All we know about Mary’s response to the Gabriel is that she simply agreed to bear Jesus. “Behold, I am the handmaid of the Lord. May it be done to me according to you word.” There is nothing to suggest from the Bible that Mary had free will. What suggests that she did have free will? Secondly, if Mary had free will without the stain of orginial sin, why cannot the same be done for us “little people” alive today? It would seem quite cruel and thus against God’s natureto bestow this stain upon our souls for no reason. Am I missing something?
