It seems from all responses that he has not. As a Catholic, yes I am asking more from my Church. Maybe it is more than they are willing to give. I am not talking about excommunication, I have no idea where that idea came from but is not even relevant to this discussion. In my work, I have encountered even priests since the revisions who are still strong supporters of the death penalty and they too quote the tradition of Catholic teaching as found in Catholic Catechism.
Popes come and go.
The Catholic Catechism remains. It is the one of the keys to the traditional and conservative Catholic supporter of the death penalty.
