AttisXVI saidOne Bishop's decision does not necessarily reflect the views of the entire Catholic church. Only the Pope can actually make a decision that represents the entire Church because his job is exactly that.
It doesn't even reflect the views of the entire Roman Catholic church.
AttisXVI is wrong. It is only when the Supreme Pontiff speaks "ex cathedral de fide" does he speak infallibly for the Church and he will do so only with the assent of a majority of his fellow bishops (as he is Bishop of Rome, first among equals), and Patriarchs and Metropolitans in communion with Rome. The Pope does not make decrees which are binding upon the Catholic Church capriciously.
Doctrines pronounced "ex cathedrA" are "infallible"; but so are all the "solemn definitions" of ecumenical councils (the last being Vatican II).
But these are not the highest authorities for choices on moral issues within the ROMAN Catholic church: As any "educated" RC knows,
"A human being must always obey the certain judgment of his conscience."
