I. Days of Penance in the United States
—Ash Wednesday and Good Friday are days of
abstinence from meat and also days of fast: that is, limited to a single full meal.
—The other Fridays of Lent are days of abstinence from meat.
—The Fridays of the year outside Lent remain days of
penance, but each individual may substitute for the
traditional abstinence from meat some other practice of voluntary self-denial or personal penance; this may be physical mortification or temperance or acts of
religion, charity or Christian witness.
II. Those Bound to Fast and Abstain
—All those who are 14 years old are bound by the law of abstinence throughout their lifetime. The law of fast binds all who are 18 years old until they begin their 60th year.
