"She obtains purity for others"

“THE Blessed Virgin exceeds the Angels in purity. She is not only pure, but she obtains purity for others. She is purity itself, wholly lacking in every guilt of sin, for she never incurred either mortal or venial sin. So, too, she was free from the penalties of sin.”

~St. Thomas Aquinas: Exposition of the Hail Mary.
