she was redeemed in anticipation of His merits on the Cross. She was also sanctified beforehand, at the moment of her conception.

How? I read nothing which attest to Mary being saved at conception, or her being sanctified beforehand. The announcement was all about Christ and His birth...She said...'Behold the handmaiden of the Lord, be it unto me as you will"...Her willingness to have what was spoken to be so. But nothing of her being saved.??????

No, I wasn’t referring to the conception of Jesus by the power of the Holy Spirit.

The Immaculate Conception means that Mary, from the first moment of HER conception, was preserved from original sin. That’s when she was sanctified.
