Jesus will indeed unify all believers under His rule with the power of the Holy Spirit. Mary has nothing to do with it. If you continue to trust your salvation to an earthly woman it will not end well. Mary can no more contribute to your salvation than your can. Christ alone is sufficient
That is your personal opinion.
The Blessed Mother was and is closer to Jesus and the Holy Spirit than anyone else on earth, and she leads all that ask for her help as God’s humble servant. Mary will help draw us closer to her Son, Jesus.
Perhaps you should read Revelations 12 about the woman, Mary and Saint Michael and the angels threw down Satan and “Now the salvation and power and kingdom of God and the authority of Christ have come, for the accuser has been thrown down...”
The more I imitate the Mother of God, the more deeply I get to know God. — Saint Maria Faustina, Diary entry 843
Saint Faustina recorded many mystical experiences with the Mother of God who taught her how to love God interiorly and how to carry out His holy will in all things. May we also come to better know the love of God by learning from our Lady and growing in devotion to her. Let us implore and be strengthened by her intercessions. The Mother of God, our heavenly Mother, desires nothing more:
I am Mother to you all, thanks to the unfathomable mercy of God. Most pleasing to Me is that soul which faithfully carries out the will of God. (Diary, 449
Perhaps you should study the Lady of Guadalupe in Spain and Mexico to understand how the Blessed Mother unified the the native Aztec Mexicans and the Spanish and converted millions to the Catholic faith.

I understand that many protestants have been taught lies about the Blessed Mother and don’t understand her role or appreciate how Mary can help us in our salvation. Yes Jesus is the just judge and the Blessed Mother has influence with her Son.
