Latin Church USCCB
- 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.
