I suppose there are two sides to every story. The St. Louis Review has a positive piece on Cardinal Rigali, recounting his efforts in St. Louis. Every other media outlet (for example, this one) focuses on the likelihood that His Eminence was moved along earlier than he would have wanted.
There is no doubt that Cardinal Rigali had exercised great influence as an American bishop, particularly in the selection of U.S. Bishops in the last decade or more. His power, reportedly, finally began to wane with the combination of his hitting the retirement age of 75 in 2010, coupled with the appointment of then-Archbishop Burke to the Congregation for Bishops in late 2009 and his being made Cardinal in 2010. Of course, I don’t give credence to such rumors– they are simply that.
The good news to come out of this change is that Philadelphia will benefit from a strong and orthodox pastor in Archbishop Chaput. A very lucky See, all things considered.
