Should the Catechism be modified? Bishop Bonny thinks it can and should be. “It was written 30 years ago and there are areas, like the one we are discussing, in which society, culture, moral theology developed fast and radically in the last 20-30 years,” Bonny said. “The Catechism is not of divine right, it can be changed by the Pope. Pope Benedict changed some paragraphs in the Catechism. (…) The Catechism is a book that is open to historicity and progress. I think there are paragraphs, which in a collegial way, could be changed for the best of the Church and for the best of our pastoral work we have to do.”
So much for your infallibe, immutable catechism, Murph.
