The article attacks not faith but doctrine.
The article indicates a failure to understand that the Catholic Church, finding it too forced and simple a distinction to portray soteriology adequately, does not buy into the faith/works dichotomy of the Reformation.
But the Catechism makes plain, though it provides too clipped an examination, that Baptism is not absolutely necessary to salvation. The writer of the article may have been a Catholic, but that's no guarantee that he knows what the RC Church teaches.
He knows. You ntold him. Certainly so have others. Jack Chick types make real money attacking “Romanism”. Follow the Money Mad Dawg, follow the money.
