Others have given you some good resources/replies. I would only add that not having the original sense of the expression in either Aramiac or Greek does hinder our full appreciation of Jesus’ words when we try to interpret such passages for ourselves. This is why Christ established his Church–to interpret his words and to teach the truth.
So, what do we know about Mary as taught by the Church? Do you find in that teaching anything that would show her to be less than faithful? And where did she do anything wrong? If you can point out such examples you might have some reason to be concerned, but there aren’t any. There are misinterpretations of Mary’s actions and words from those who wish to downplay or ignore her part in God’s ongoing plan of salvation of mankind. But in reality we don’t honor her enough for all she did and still does as the faithful “handmaid of the Lord.”
We have some Biblical information on Mary:
Most Pure (Mt. 1:18, 20, 23; Lk 1:27,34)
18 Now the generation of Christ was in this wise. When as his mother Mary was espoused to Joseph, before they came together, she was found with child, of the Holy Ghost.
20 But while he thought on these things, behold the angel of the Lord appeared to him in his sleep, saying: Joseph, son of David, fear not to take unto thee Mary thy wife, for that which is conceived in her, is of the Holy Ghost.
23 Behold a virgin shall be with child, and bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.
27 To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin’s name was Mary.
34 And Mary said to the angel: How shall this be done, because I know not man?
Most Prudent (Lk 2:19, 51)
19 But Mary kept all these words, pondering them in her heart.
51 And he went down with them, and came to Nazareth, and was subject to them. And his mother kept all these words in her heart.
Most Humble (Lk 1:48)
48 Because he hath regarded the humility of his handmaid; for behold from henceforth all generations
shall call me blessed.
Most Faithful (Lk 1:45; Jn 2:5)
45 And blessed art thou that hast believed, because those things shall be accomplished that were spoken to thee by the Lord.
5 His mother saith to the waiters: Whatsoever he shall say to you, do ye.
Most Devout (Lk 1:46-7; Acts 1:14)
46 And Mary said: My soul doth magnify the Lord.
47 And my spirit hath rejoiced in God my Saviour.
14 All these were persevering with one mind in prayer with the women, and Mary the mother of Jesus, and with his brethren.
Most Obedient (Lk 1:38; 2:21-2, 27)
38 And Mary said: Behold the handmaid of the Lord; be it done to me according to thy word. And the angel departed from her.
21 And after eight days were accomplished, that the child should be circumcised, his name was called JESUS, which was called by the angel, before he was conceived in the womb.
22 And after the days of her purification, according to the law of Moses, were accomplished, they carried him to Jerusalem, to present him to the Lord:
27 And he came by the Spirit into the temple. And when his parents brought in the child Jesus, to do for him according to the custom of the law,
Most Poor (Lk 2:7)
7 And she brought forth
her firstborn son, and wrapped him up in swaddling clothes, and laid him in a manger; because there was no room for them in the inn.
Most Patient (Jn 19:25)
25 Now there stood by the cross of Jesus, his mother, and his mother’s sister, Mary of Cleophas, and Mary Magdalen.
Most Merciful (Lk 1:39, 56)
39 And Mary rising up in those days, went into the hill country with haste into a city of Juda.
56 And Mary abode with her about three months; and she returned to her own house.
Most Sorrowful (Lk 2:35)
35 And thy own soul a sword shall pierce, that, out of many hearts, thoughts may be revealed.
