At least the growing back of a limb could be classed as a genuine miracle.
The quality of "miracles" that the Catholic church will accept seems to be slipping, IMO.
The reason given that Cardinal Newman was deserving of Beatification. according to the church, was a single instance of an alleged "miracle cure" by a Catholic Deacon, who, suffering from stenosis, had a laminectomy. According to him, hearing that the church was seeking evidence of a miracle in order to beatify Newman, he prayed to Cardinal Newman to relieve him of his alleged extreme and -according to him and his devout catholic surgeon - untreatable pain, and was immediately rewarded by a warm feeling and cessation of pain.
I am amazed that it just takes one anecdote to generate a miracle, in the eyes of the catholic church.......
