“[T]hese vestments, they are but a little detail of ritual, yet they too are a wonderful witness of our unbroken continuity… If Ambrose or Augustine or Leo came back now… [and] wandered into a Catholic church, there and there alone they would be at home. They would see the sacrifice they offered still shown forth in the same way. They would recognize the prayers and understand the language that they used. And as they gazed from the barbarous clothes of the congregation to the altar they would see at least one man dressed as they were… So the ghosts of the mighty men who spread the name of Christ throughout the dying Empire would know that, in spite of all changes, their Church still stands, after sixteen long centuries.”
