A Statement Issued by the National Conference of Catholic Bishops November 18, 1966
Vigils and Ember Days
17 … We impose no fast before any feast-day, but we suggest that the devout will find greater Christian joy in the feasts of the liturgical calendar if they freely bind themselves, for their own motives and in their own spirit of piety, to prepare for each Church festival by a day of particular self-denial, penitential prayer and fasting.
Christ Died for Our Salvation on Friday
23 Friday should be in each week something of what Lent is in the entire year. For this reason we urge all to prepare for that weekly Easter that comes with each Sunday by freely making of every Friday a day of self-denial and mortification in prayerful remembrance of the passion of Jesus Christ.
24 Among the works of voluntary self-denial and personal penance which we especially commend to our people for the future observance of Friday, even though we hereby terminate the traditional law of abstinence binding under pain of sin, as the sole prescribed means of observing Friday, we give first place to abstinence from flesh meat. We do so in the hope that the Catholic community will ordinarily continue to abstain from meat by free choice as formerly we did in obedience to Church law. …
25 Every Catholic Christian understands that the fast and abstinence regulations admit of change, unlike the commandments and precepts of that unchanging divine moral law which the Church must today and always defend as immutable. This said, we emphasize that our people are henceforth free from the obligation traditionally binding under pain of sin in what pertains to Friday abstinence, except as noted above for Lent. We stress this so that “no” scrupulosity will enter into examinations of conscience,confessions, or personal decisions on this point.
26 Perhaps we should warn those who decide to keep the Friday abstinence for reasons of personal piety and special love that they must not pass judgment on those who elect to substitute other penitential observances. Friday, please God, will acquire among us other forms of penitential witness which may become as much a part of the devout way of life in the future as Friday abstinence from meat. In this connection we have foremost in mind the modern need for self-discipline in the use of stimulants and for a renewed emphasis on the virtue of temperance, especially in the use of alcoholic beverages.
