"There was no Original Sin in Mary"

"WE do not say that every pink and blue doll from an Art Repository is a satisfactory symbol of the Mother of God. But we do say that it is less of a contradiction than exists in a person who says there is no Original Sin in anybody, and then calls it Mariolatry to say there was no Original Sin in Mary."

~G.K. Chesterton: The Thing.
