" As the priest and Levite thought they could follow the Torah and not offer aid to the stranded, dying man (Luke 10:25–37), so Isaiah’s community thought they could abstain from food and pass by the needs of others on their way to God. Fasting never stands alone. Fasting, if it is genuine, brings us into a communal spirituality because it is a response to the lack of justice in the community. "
