Oh yes she can save many people, she already did many times in the past and up to the present. She does it because Jesus allows it. Christ alone is enough but we aren't always worthy to come to His presence, thus he gave us His very own mother to help all of us. If you don't want to believe it's up to you. I've already shared enough info to you and the internet is open for everyone.

We Catholics will keep believing what Jesus taught His apostles: Mama Mary is our spiritual mother. God bless you! 🙏
