Why are Fridays during Lent days of abstinence?
This is because Jesus died for our sins on Friday, making it an especially appropriate day of mourning our sins (just as Sunday, the day on which he rose for our salvation is an especially appropriate day to rejoice) by denying ourselves something we enjoy. During the rest of the year Catholics in this country are permitted to use a different act of penance on Friday in place of abstinence, though all Fridays are days of penance on which we are required to do something expressing sorrow for our sins, just as Sundays are holy days on which we are required to worship and celebrate God's great gift of salvation.
