How can one be "pure" and "unstained" if she was supposedly stained with sin? That doesn't make sense.
Also have some more quotes I found on the matter:
St. Cyril of Jerusalem
Pure and spotless is this birth. For where the Holy Spirit breathes, all pollution is taken away, so that the human birth of the Only-begotten from the Virgin is undefiled. (Catechetical Lectures, XII, 31-32; Gambero, 140)
St. Gregory of Nyssa
It was, to divulge by the manner of His Incarnation this great secret; that purity is the only complete indication of the presence of God and of His coming, and that no one can in reality secure this for himself, unless he has altogether estranged himself from the passions of the flesh. What happened in the stainless Mary when the fulness of the Godhead which was in Christ shone out through her, that happens in every soul that leads by rule the virgin life. (On Virginity, 2; NPNF 2, Vol. V, 344)
[T]he power of the Most High, through the Holy Spirit, overshadowed the human nature and was formed therein; that is to say, the portion of flesh was formed in the immaculate Virgin. (Against Apollinaris, 6; Gambero, 153)
St. Ambrose
. . . Mary, a Virgin not only undefiled but a Virgin whom grace has made inviolate, free of every stain of sin. (Commentary on Psalm 118, 22, 30; Jurgens, II, 166)
What is greater than the Mother of God? What more glorious than she whom Glory Itself chose? What more chaste than she who bore a body without contact with another body? (Virginity, II, 6; NPNF 2, Vol. X, 374)
St. Epiphanius
Mary, the holy Virgin, is truly great before God and men. For how shall we not proclaim her great, who held within her the uncontainable One, whom neither heaven nor earth can contain? (Panarion, 30, 31; Gambero, 127)
St. Jerome
‘There shall come forth a rod out of the stem of Jesse, and a flower shall grow out of his roots.’ The rod is the mother of the Lord–simple, pure, unsullied; drawing no germ of life from without but fruitful in singleness like God Himself… Set before you the blessed Mary, whose surpassing purity made her meet to be the mother of the Lord. (Letter XXII. To Eustochium, 19, 38; NPNF 2, Vol. VI, 29, 39; cf. Gambero, p. 213: “whose purity was so great that she merited to be the Mother of the Lord”)
Indeed how inferior they are, in terms of holiness, to blessed Mary, Mother of the Lord! (Contra Pelagianos, 1, 16; Gambero, 212)
St. Cyril of Alexandria
Hail, Mary Theotokos, Virgin-Mother, lightbearer, uncorrupt vessel . . . Hail Mary, you are the most precious creature in the whole world; hail, Mary, uncorrupt dove; hail, Mary, inextinguishable lamp; for from you was born the Sun of justice . . . Through you, every faithful soul achieves salvation. (Homily 11 at the Ecumenical Council of Ephesus; Gambero, 243, 245)
I see the assembly of the saints, all zealously gathered together, invited by the holy Mother of God, Mary, ever-virgin . . . We hail you, O Mary Mother of God, venerable treasure of the entire world, inextinguishable lamp, crown of virginity, scepter of orthodoxy, imperishable temple, container of him who cannot be contained . . . Through you, the Holy Trinity is glorified; the precious Cross is celebrated and adored throughout the world; heaven exults, the angels and archangels rejoice, the demons are put to flight, the devil, the tempter, falls from heaven, the fallen creation is brought back to paradise, all creatures trapped in idolatry come to know of the truth. (Homily IV Preached at Ephesus Against Nestorius; Gambero, 247-248)
