This is the paragraph in question I presume:
“Our Lord and Lady were both, of course, conceived without sin, but St. John the Baptist, though not conceived in this way, was filled with grace in the womb of his mother, the aged Elizabeth, and so was *born *without original sin. This is evident by his recognizing the Savior even in the womb”
I am no authority on this subject, but I must say I am as surprised as you are at this explanation. This is why: The soul comes into being at conception and not after spending several months in the womb. All sorts of people have been anointed and filled with the Holy Spirit, but the Holy Spirit did not remove the stain of original sin from their soul. What being filled means; the individual soul is being filled to capacity. I can accept the Baptist being baptized and confirmed inside Elisabeth’s womb, but I am very reluctant to accept this would have washed away the original sin which must have already been on the Baptist’s soul. You see, all the examples I brought up, Adam, Eve, Mary and Jesus were without original sin at the moment of their creation/conception. If the Baptist’s original sin would have been washed away, than the Holy Spirit would have washed away the original sin from the soul of every Old Testament prophet and Catholic saint as well. This makes virtually no sense to me. Unless I am corrected by someone with authority, real and not perceived, I will not accept this. I have seen this site and I will go to it for reference again, but for those, who are embarking on the journey toward the Catholic faith, I would not recommend it, unless as I said someone with real theological authority can explain it otherwise. As you see we are arguing back and forth, our faith is not cut and dry and it may seem overwhelming at first, but it does get easier.
