Fr. Z posts a wonderful article with his commentary about the miracle of Our Lady of Guadalupe on his blog.
Through this miracle, God drew an entire people to himself...all through the intercession of Jesus's blessed mother. How very evangelical! Mary is the model both of the Church and of all things evangelical. Her message is always that spoken at the wedding feast at Cana: "Do whatever he tells you." Mary's soul always "magnifies the Lord."
Through the intercession of the Blessed Mother Mary--our Blessed Mother--may the divisions between Christians be healed and perfect unity attained so that the "world may know" that the Father sent the Son (John 17), and may all people be drawn to Jesus Christ, the only savior of the world.
I would propose to my non-Catholic brothers and sisters in Christ that our collective evangelical efforts will be hindered and even damaged until we are in union with each other and with Jesus's and Mary's evangelical plan.
