The reason for why Catholics eat fish on Friday is simple: the Catholic Church has historically urged people to abstain from meat on Fridays. Meat is the flesh of warm-blooded land animals, whereas fish are cold-blooded water dwelling creatures. Because of this, many people began to eat fish flesh on Fridays. In time, this custom became a staple of Catholic culture. Although many Catholics were reluctant to eat fish during the fasting period, it still became a way for them to get enough protein.
While Catholics abstain from eating meat on certain days, they eat fish on Fridays, as warm-blooded animals have already sacrificed their life to provide for human needs. This practice was encouraged by the Church because it was good for the soul and promotes a spiritual life. However, people are naturally inclined to look for loopholes in new rules, so why do Catholics eat fish on Friday?
Although the practice of abstaining from meat on Fridays has biblical implications, it has also become a common custom in Catholic households worldwide. While the church has never made it mandatory, the practice of eating fish on Friday has become increasingly popular with vegetarians. The next time you go to a Catholic home, don’t forget to bring a nice bottle of wine to match the fish. There are many varieties of fish and wines that are delicious with this meal.
