Following the fall of Constantinople, an ascetic while walking through the ruins of the city came before a destroyed, desolated Church Temple and saw an unspeakable sight: A female pig with her newborn on the Holy Prothesis (table of Offerings)! He then started crying and sorrowing that this holy place had been profaned. At that point an Angel of the Lord appeared saying:
“Abba, why are you weeping? Do you not know that what you have seen is more acceptable to God than the unworthiness of the priests who used to celebrate here?”
And the Angel vanished.
