I Came to Cast Fire upon the Earth

 From Catholic Exchange:

When we pray the Rosary, we are gathered around Our Blessed Mother as one priest said, just like the Apostles and disciples gathered in prayer with Her in the Upper Room in preparation for Pentecost. And the Holy Spirit descends into our hearts through the Heart of Our Blessed Mother Who is present with us when we pray. While we are praying the Our Father, which Jesus Himself taught us, and the Hail Mary containing the words God spoke to Our Blessed Mother through the Angel Gabriel, we are meditating on the Mysteries of the Life of Jesus. The Life of Jesus is profoundly and inseparably intertwined with that of Our Blessed Mother. These Mysteries are not merely past events. What happens to God, and Jesus is God, remains present for all eternity because God is the eternal present. His acts are theandric—they are acts of God, thus they remain eternally present in Him, and He in them. The Mysteries of His life remain ever present in Him, and He in them. As we meditate on these Mysteries then, we are gazing with Our Blessed Mother at Christ Who is present with us when we pray the Rosary as St. Louis de Montfort says. We are gazing at the Living God; we are in contact with Him. This contact purifies us since “God is a consuming fire.” (Hebrews 12:29). His gaze purifies us. In this prayer—the Rosary—we gaze at Christ through Mary, with Mary, and He gazes at us. (Read more.)
