Nicetas of Remesiana

And now, beloved, I ought to say a word about the antiquity of the tradition and the utility of vigils. It is easier to begin a work if we keep before our eyes how useful it is. The devotion to vigils is very old. It has been a household tradition among the saints. It was the prophet Isaiah who cried out to the Lord: "My soul has yearned for you in the night. Indeed, my spirit within me seeks you early in the morning."
