I never said that sin doesn’t exist among Catholics. God estabished authority, which is to be respected as He’s ordained it. The faithful can’t consecrate, absolve from sins, etc. True, Satanists would oppose all Christians, but they know that their true enemy is the Church that Jesus Christ established. The devil did his job in part by inspiring Protestantism, separating the flock. St. Augustine: He who will not have the Church for his mother cannot have God for his Father.
Why attack the Protestants? The devil has separated them from the protection of the Bride of Christ and Her sacraments. You seem to be a “to-each-his-own” kind of person, by your statements, not really believing in an ultimate truth. (That statement was not meant to be rude, just an observance.) Truth is truth, you can’t pick and choose. It exists or it doesn’t. If my assumption is correct, then there’s no point in debating anything, ever. If it was incorrect, then the matter should be seriously looked into before condemning it.
