The very early date to which this homily is now assigned makes its slightest allusions to the New-Testament canon of very great importance. I have ventured to indicate a few such, even where they may be mere allusions, not textual quotations: as, e.g., on p. 517, at notes 20 and 22, slight indications of a reference to the Second Epistle of St. Peter and to the Apocalypse.
