HaHaHa...Your catechism in not God's bible...All it is is a commentary on some of the scripture and a poor one at that...
If the person does not believe that the Catholic Church is the church that Christ founded, they must repent and believe.
Repent and believe, in YOUR RELIGION...So all this stuff about Protestants who are baptized can be saved is a bunch of baloney...Since they can not be forgiven for anything...
But they wont have the psychological certainty of Gods forgiveness that Catholics receive in Confession, nor the graces that the sacrament imparts.
And that is the craziest part of all...We are not looking for the psychological anything...Christianity is not psychological...
Christianity is an operation...It is a spiritual circumcision of the heart...It is NOT psychology of the mind...That's why the bible is so foreign to you guys...That's why you need someone to tell you what it says...
"If he will not listen to the church, treat him as a pagan or tax collector." --Jesus
Catholics read the whole Bible, and take Jesus' commands seriously.
