No. What one has to look to is the prescriptions set in place by the territory where a Catholic lives…normally, at the level of the national episcopal conference, but with the understanding that the diocesan bishop may have promulgated particular law, which should be followed by those in his diocese.
The following, as one example, is from the US Conference of Catholic Bishops:

*Christ Died for Our Salvation on Friday
- Gratefully remembering this, Catholic peoples from time immemorial have set apart Friday for special penitential observance by which they gladly suffer with Christ that they may one day be glorified with Him. This is the heart of the tradition of abstinence from meat on Friday where that tradition has been observed in the holy Catholic Church.
- Changing circumstances, including economic, dietary, and social elements, have made some of our people feel that the renunciation of the eating of meat is not always and for everyone the most effective means of practicing penance. Meat was once an exceptional form of food; now it is commonplace.
- Accordingly, since the spirit of penance primarily suggests that we discipline ourselves in that which we enjoy most, to many in our day abstinence from meat no longer implies penance, while renunciation of other things would be more penitential.
- For these and related reasons, the Catholic bishops of the United States, far from downgrading the traditional penitential observance of Friday, and motivated precisely by the desire to give the spirit of penance greater vitality, especially on Fridays, the day that Jesus died, urge our Catholic people henceforth to be guided by the following norms.
- Friday itself remains a special day of penitential observance throughout the year, a time when those who seek perfection will be mindful of their personal sins and the sins of mankind which they are called upon to help expiate in union with Christ Crucified.
- 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.
- 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. Our expectation is based on the following considerations:
We shall thus freely and out of love for Christ Crucified show our solidarity with the generations of believers to whom this practice frequently became,especially in times of persecution and of great poverty,no mean evidence of fidelity to Christ and His Church.
We shall thus also remind ourselves that as Christians, although immersed in the world and sharing its life, we must preserve a saving and necessary difference from the spirit of the world. Our deliberate,personal abstinence from meat, more especially because no longer required by law, will be an outward sign of inward spiritual values that we cherish.
- 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.
- 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.
- It would bring great glory to God and good to souls if Fridays found our people doing volunteer work in hospitals, visiting the sick, serving the needs of the aged and the lonely, instructing the young in the Faith, participating as Christians in community affairs, and meeting our obligations to our families, our friends,our neighbors, and our community, including our parishes, with a special zeal born of the desire to add the merit of penance to the other virtues exercised in good works born of living faith.*
