Whilst I walk in the spirit, I do not think it necessary to be subject to any visible organization.

The Catholic Answers

You may say that you believe it unnecessary. But pay attention to the words of Christ I have just quoted. He thought it necessary, and He has the right to map out the kind of religion we are to accept. If Christians had to accept such disciplinary authority in the time of the Apostles, they must accept it now. Christianity is Christianity. It does not change with the ages. If it did, it would lose its character, and not remain the religion of Christ, to which religion alone He attached His promises. And remember His prediction that His flock would be one fold with one shepherd. Jn. X., 14. You would have sheep, not gathered into one fold, but straying anywhere and everywhere, having no shepherd with any real authority over them.
