Can you please explain to me how Catholics are not Christians?

St Irenaeus first used the term "catholic" around 120ad. Catholics do not believe that the bible alone has all the answers as no where does the bible state or teach this. Jesus never said for us to read the bible as it did not come into existence some time later. The Catholics put together the canon to form the bible and the so-called reformers messed up the rest. The Protestant doctrines of sola scriptura and sola fide were made up by Luther and others in the Middle Ages in order to split from Rome. Neither is true. All they have to show for their work is 22,000 protestant denominations that are hopelessly divided and agree on nothing, except allowing the tele-evangelists to make millions.
