There is a story from the Desert Fathers that bears repeating often:
When Abba Holarion (the Great) was old, he determined to leave his monastery for a while and take a trip through the Known World. Anon, he cane to Cyprus, where Abba Epiphanios (the Jew) was Bishop; this same Epiphanios had once been a monk at Scetis. Abba Holarion arrived at the episcopal residence, received a cordial greeting, and spent the afternoon in edifying converrsation with the bishop.
When it drew on to evening, the bishop summoned his deacon and bade him prepare supper; the deacon returned with a freshly killed and plucked chicken. Abba Hilarion was aghast. "Forgive me, Father, never since I took the habit in Egypt have my lips tasted meat," he said. Abba Epiphanios replied, "Indeed, when I took the habit in Egypt, I made a vow to that effect; but now that I'm a bishop, I'm obliged to eat whatever my people provide me." Then, after some thought, he added, "When I took the habit in Egypt, I made a vow never to go to bed angry with anyone." Abba Hilarion replied, "Forgive me, Father, your way is better than mine."
