That's broken down now, says Reese, because, "Many bishops believe they are being prophetic on the issues they think are important and these bishops think abortion is the pre-eminent issue of our time, like slavery and genocide were in the past. They are true believers and they are speaking out, even if, like Archbishop Burke, they have absolutely zero authority to tell someone else in the USA what they can do."
Fr. Z has some great commentary on the subject (here)
Archbishop Raymond Burke apologized for the misuse of his comments from an interview with Randall Terry regarding the actions of other United States bishops regarding Catholic politicians who support abortion. (here)
