He also claims the Catholic cannot go all the back as well. Sebastian, thank you for your honesty. Many will not admit that their church does not go all the way back to the Apostles. The Catholic Church is the Church that Christ founded. Jesus appointed Peter as the first leader of the Church, followed by Linus all the way down to our present Pope. And yes the descriptive term catholic was applied by Ignatius of Antioch in the year 110. The name stuck and so that is why the Church founded by Jesus and the Apostles is called Catholic today. Protestants today have still kept many of these Catholic understandings such as the inspiration of the Bible, the Holy Trinity the two natures of Christ (Jesus Christ fully God and fully man) and many other teachings and this is why we call them separated brothers.
