Is it from the door of the sepulcher, or of your own hearts? From the tomb, or from your own eyes? You whose heart is shut, whose eyes are closed, are unable to discover the glory of the open grave. Pour then your oil, if you wish to see that glory, not on the body of the Lord, but on the eyes of your hearts. By the light of faith you will then see that which through the deficiency of faith now lies hidden in darkness.

Peter Chrysologus,  Sermon 82, in Mark (The Ancient Christian Commentary on Scripture), edited by Thomas C. Oden & Christopher A. Hall, IVP, 1998, 229-230.

I seem to find myself becoming more and more aware of the need for a sustained reflection on the relationship between epistemology and asceticism.
