"A division within the Church has never occurred, nor indeed can one take place, while apostasy from the Church has and will continue to occur after the manner of those voluntarily fruitless branches which, having withered, fall away from the eternally living theanthropic Vine—the Lord Christ (John 15:1-6). From time to time, heretics and schismatics have cut themselves off and have fallen away from the one and indivisible Church of Christ, whereby they ceased to be members of the Church and parts of her theanthropic body. The first to fall away thus were the gnostics, then the Arians, then the Macedonians, then the Monophysites, then the Iconoclasts, then the Roman Catholics, then the Protestants, then the Uniates, and so on—all the other members of the legion of heretics and schismatics.”
