"You are the ones who are happy; you who remain within the Church by your Faith, who hold firmly to the foundations of the Faith which has come down to you from Apostolic Tradition. ... No one, ever, will prevail against your Faith, beloved Brothers. And we believe that God will give us our churches back some day. ... 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, Letter to His Flock, 4th. c., Coll. selecta SS. Eccl. Patrum, Caillau and Guillou, Vol. 32, pp. 411-412
