The Rosary means “Crown of Roses.” Each Hail Mary offers Our Lady a rose, and a full Rosary crowns her with love.
It is called the queen of prayers because it tells the story of our salvation through the joyful, sorrowful, glorious, and luminous mysteries.
Mary always prays with us, and what she asks, Jesus grants. The Rosary is a powerful weapon against evil and a path to peace.
Even though it may feel repetitive, it’s like saying to God and Mary over and over: “I love You.”
