Ascetic Life and Practice
Macedonius's regimen was marked by extreme austerity. For much of his life his sole sustenance was barley moistened with water, the practice that earned him the Greek epithet 'Krithophagos' (Barley-Eater). His decades-long residence in a deep pit, open to the sky, gave rise to the Syrian epithet 'Gouvas,' meaning 'pit.'
He understood food not as indulgence but as necessity, reportedly regarding it as 'medicine that could be taken to stave off death because it is not lawful to shorten one's life to shun labors and conflicts.' Accordingly, he accepted baked bread only when his bodily strength failed in old age, and consented to a narrow constructed cell only late in life.
