Thus, the more violently they try to occupy the places of worship, the more they separate themselves from the Church. They claim that they represent the Church; but in reality, they are the ones who are expelling themselves from it and going astray. Even if Catholics faithful to Tradition are reduced to a handful, they are the ones who are the true Church of Jesus Christ.

- St Athanasius
