Just don't wanna deal with the SINs of the popes; do you...
Well; I wouldn't either, so we're together on this one.
Why, we indeed had sinful popes; in fact only some of the popes were recognized as saints. To think that if one is Catholic by religious affiliation means the one is “saved” is bringing the false salvation by faith alone concept to Catholicism. While Catholics receive special assurances of salvation through the sacraments of the Church available to them, they are judged just like Protestants by their works and therefore saved only when a lifetime of mature well-formed faith has lead them to union with Christ.
