Ave Maria!
“Some professors held that the affirmation according to which the Most Holy Virgin was immune from the stain of original sin is an offense to the dignity of Christ the Lord, who redeemed everyone without any exception and died for all. But isn’t it precisely for this, by the merits of His future death, that He did not even permit that She be stained by any sort of sin? Isn’t it precisely for this that He redeemed Her in the most perfect way?” (SK #1081)
