Sorry if I didn't make that clear (I was just responding to the doubters of the CURRENT canonizations). This proposal is just dumb. If he's a saint, he can manage to get a miracle or two.
I think this article overstates the consideration JP II is giving this - it makes it appear that he's about to implement this rule, but the only actual source just says that a proposal has been presented to him.
Yesterday Cardinal Tarcisio Bertone, the Archbishop of Genoa, disclosed that Cardinal Joseph Ratzinger, the head of the Congregation for the Doctrine of the Faith and the Pope’s ideologial “enforcer” for two decades, had presented a formula for the abolition of the “the miracle clause” to the Pope. Cardinal Bertone said that there was a growing feeling in the Vatican that the need for miracles for both beatification and canonisation was “anachronistic”.
If Cardinal Ratzinger is the one proposing it, then it DEFINITELY has the ear of the Pope.
