Mary conceived without sin? No, she was not. She was human like all the rest of us.
Catholic Church teaching - The Dogma of the Immaculate Conception.
Sin never made anyone human. Adam and Eve were created without sin -- did they have to sin to become human? God forbid! Jesus was perfectly human and perfectly divine, yet never sinned. Think about your objection, because it leads to some awful conclusions.
“....Mary conceived without sin? No, she was not. She was human like all the rest of us...”
Do we have to go thru this again?
Yes Mary was human. She was created just like the rest of us. Yes she had human parents, Joachim and Anna. They were very devout Jews and longed for a child. They prayed unceasingly according to narratives written that were not included in the Bible.
“Conceived without sin” means that as the selected woman to be the Mother of the Messiah, God favored her with the Holy Spirit from her natural conception in order that His Divine Son would not be ever subjected to the power of Satan. That is why the angel Gabriel saluted her with the phrase, “Full of Grace.”
Since God so favored her, I would never presume to assume equality with Mary, the Mother of Jesus. To my knowledge no other woman has ever been so privileged.
Mary was the new Eve. Eve was created without sin.
