Newman currently (technically) ranks as a "Venerable", and this miracle paves the way to being raised to the level of "Blessed", the last stop before Sainthood.
Start your prayers now. Most people are quick to turn to the "old reliables" when it comes to the Communion of Saints. I like to tell people, whilst Saints Anthony, Jude, Rita, Rocco, etc., are great, why not turn to a "Blessed" of the Church. They need that last miracle for Canonization. Besides, if it's your miracle that pushes him/her over the top, you get a great seat for the Pope's ceremony.
