[MarMema]

If Mary were Immaculate, then from whom would Christ have assumed our fallen nature? If Christ did not assume our fallen nature, we are not redeemed.

If Mary were Immaculate, then from whom would Christ have assumed our fallen nature? If Christ did not assume our fallen nature, we are not redeemed.

Original sin is spiritual death; separation from the living God. Jesus could not possibly have been in such a state, for His human nature could not be simultaneously hypostatically united to God the Son and separated from God by sin. So even if Mary had been a sinner, Christ would not have contracted original sin from her. However a sinful mother would have been a dishonor to Him so she was granted this special grace.

I am curious why you deny this grace to the very Mother of God, Spouse of the Holy Spirit?
