I have a question of my own that I would like to pose:
If Mary was not conceived immaculately, how was she able to live a life of perfect holiness when even the greatest of all other saints have failed to do so?
Good breeding: Luke 1:5 In the days of Herod, king of Judea, there was a priest named Zechari'ah, of the division of Abi'jah; and he had a wife of the daughters of Aaron, and her name was Elizabeth. 6 And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless 7 But they had no child, because Elizabeth was barren, and both were advanced in years...13 But the angel said to him, "Do not be afraid, Zechari'ah, for your prayer is heard, and your wife Elizabeth will bear you a son, and you shall call his name John...34 And Mary said to the angel, "How shall this be, since I have no husband?" 35 And the angel said to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy, the Son of God. 36 And behold, your kinswoman Elizabeth in her old age has also conceived a son; and this is the sixth month with her who was called barren 37 For with God nothing will be impossible." 38 And Mary said, "Behold, I am the handmaid of the Lord; let it be to me according to your word." And the angel departed from her. 39 In those days Mary arose and went with haste into the hill country, to a city of Judah, 40 and she entered the house of Zechari'ah and greeted Elizabeth. 41 And when Elizabeth heard the greeting of Mary, the babe leaped in her womb; and Elizabeth was filled with the Holy Spirit 42 and she exclaimed with a loud cry, "Blessed are you among women, and blessed is the fruit of your womb! 43 And why is this granted me, that the mother of my Lord should come to me? 44 For behold, when the voice of your greeting came to my ears, the babe in my womb leaped for joy. 45 And blessed is she who believed that there would be a fulfilment of what was spoken to her from the Lord." ....7:18 The disciples of John told him of all these things. 19 And John, calling to him two of his disciples, sent them to the Lord, saying, "Are you he who is to come, or shall we look for another?" 20 And when the men had come to him, they said, "John the Baptist has sent us to you, saying, 'Are you he who is to come, or shall we look for another?'" 21 In that hour he cured many of diseases and plagues and evil spirits, and on many that were blind he bestowed sight. 22 And he answered them, "Go and tell John what you have seen and heard: the blind receive their sight, the lame walk, lepers are cleansed, and the deaf hear, the dead are raised up, the poor have good news preached to them. 23 And blessed is he who takes no offense at me." 24 When the messengers of John had gone, he began to speak to the crowds concerning John: "What did you go out into the wilderness to behold? A reed shaken by the wind? 25 What then did you go out to see? A man clothed in soft clothing? Behold, those who are gorgeously appareled and live in luxury are in kings' courts. 26 What then did you go out to see? A prophet? Yes, I tell you, and more than a prophet. 27 This is he of whom it is written, 'Behold, I send my messenger before thy face, who shall prepare thy way before thee.' 28 I tell you, among those born of women none is greater than John.
I'd comment, but I am interested in whay you have to say.
