How shall I answer the questions about Mary?

Her Immaculate Conception:  Mary is ‘full of grace’ through God.  She was redeemed from the moment of her conception.  When the Angel Gabriel greeted her, she was greeted with, “Hail Mary, full of grace” meaning she had been created without sin by God.  See Luke 1:26-38.  Our Blessed Mother Mary still had to be redeemed by God just as we must experience redemption, yet God redeemed Mary, who is the Ark of the New Covenant, at the moment of her conception so that she would be a purified vessel ready to receive the Messiah, Jesus, the New Covenant,.  She was purified by God just as the Ark of the Old Covenant was purified through God’s instructions to be made of pure gold to receive the Old Covenant.  The Ark of the Old Covenant was a foreshadowing of the promises to come.  This truth was recognized as Dogma in 1854 by Pope Pius IX.  See CCC (Catechism of the Catholic Church) 491
