BioEdge has a profile of some of Pope Francis' bioethical positions, which they translated from a book in Spanish from when the Pope was archbishop in Argentina.
I think it's safe to say that we should not expect the Catholic Church to be modifying its long-held positions any time soon. Sorry to disappoint the progressives out there, who were hoping for a liberalization of teaching regarding things like contraception, abortion, euthanasia, and all that. Yes, the Pope IS Catholic.
Personally, I can't wait to see if the Pope eventually says anything as Pope about these topics.
