"Idolaters! You are not true Eastern Orthodox Christians," the monk at St Spas monastery near Yambol scolded us while he was locking the gate of the supposedly miraculous cave spring his abode is famed for. Our sin? We had not lit candles when we entered the church. He, however, did not see any contradiction in the fact that the veneration of "healing" springs is a tradition that Eastern Orthodoxy in Bulgaria has inherited from paganism.
