Inexplicably, yours and other protestant “explanations” of the role of the Blessed Mother fail to account for simple logic. It would have been simply illogical for the Perfect Christ to have come from an imperfect Mary, thus the Church that JESUS founded and promised would not be prevailed against, through Divine guidance as promised by Christ Himself (“…and the gates of hell shall NOT prevail against it.”) was forced to reckon with this. How could imperfection give birth to Perfection? The ONLY logical explanation is that Mary HAD to have been born without the stain of original sin. I would invite you to watch “Coming Home” on EWTN and listen to the wonderful and remarkable stories of those who found The Holy Roman Catholic Church had ALL the answers that Protestantism, Judaism, Buddhism, Islam, and the others could not offer.
Our response – Let’s take a look at your simple logic. You said it would be “simply illogical for the Perfect Christ to have come from an imperfect Mary.” You also said, “How could imperfection give birth to Perfection? The ONLY logical explanation is that Mary HAD to have been born without the stain of original sin.” Are you sure you want to stick with this logic? If so, then you must conclude that both of Mary’s parents were born without sin as well. After all, if she was born sinless, and imperfection cannot give birth to perfection, then her parents must have been perfect. If that’s so, then all four of her grandparents must also have been perfect and sinless, and so on and so forth. That perfection would then have been passed on to Mary’s siblings, her cousins, aunts and uncles, etc. etc. The simple logic you wish to argue has now created veritable nation of perfect people. Is this your contention? I think you can see how this argument falls. The real answer doesn’t come burdened with this sort of achille’s heel. You’re assuming what came from Mary was perfect. However, God the Son existed before Mary. The Son has always existed. His perfection is found in His eternal deity. Mary’s role was in the production and nurturing of His human body. His body was not perfect until His assumption. Before then, His body bled, bruised, and scarred. Scripture tells us He was nothing special to look at — nothing particularly attractive about Him. His body was very, very human and imperfect. His divine nature was perfect, but that did not come from Mary.
