“...when he speaks “ex Cathedra” he cannot err.....ever....”
Only God speaks without error. No man, not even the ‘Pope’ can speak without error. God never ordained that. Period. The Catholic Church ‘defines’ ‘ex Cathedra’...how convenient.
sure he can....God promised it and so far...so good...for 2013 years the pope has never said anything ..Ex Cathedra...that was in error.
