<The Vatican said that what Curran pedals is not Catholic theology.>
The Vatican issued a decree to that effect concerning Father Kung, but never about Curran.  Of course, I could be mistaken, in which case I'm sure you'll cite the relevant document.
It is Curran -- not "the Vatican" -- who has been teaching in conformity with the mind of the church for all these years, if the "mind of the church" is understood to align with the faith and practice of the People of God.
