Why Do Catholics Eat Fish on Friday

Why do people eat fish on Fridays instead of fasting?

The tradition of eating fish on Fridays dates back to the early days of Christianity. According to Christian tradition, Jesus Christ died on a Friday. As a way to commemorate his sacrifice, early Christians began to fast on Fridays. This fast originally meant abstaining from all food, but it was later relaxed to include only meat.

There are a few reasons why fish was considered an acceptable substitute for meat on Fridays:

  1. Fish were not considered warm-blooded animals, like humans, so they were not seen as being as closely associated with Christ.
  2. Fish were a symbol of life and abundance, which was seen as a fitting contrast to the death of Christ.
  3. Fish were a relatively abundant and affordable food source, making them a practical choice for many people.

Over time, the tradition of eating fish on Fridays became increasingly popular, and the Catholic Church eventually adopted it as an official rule. This rule required all Catholics to abstain from meat on Fridays, allowing them to eat fish. This rule was in place for centuries and is still followed by many Catholics today.

Recently, the tradition of eating fish on Fridays has become less strictly observed, but it is still widespread among many Christians. Some people choose to eat fish on Fridays as a way to connect with their faith and commemorate the sacrifice of Christ. Others enjoy the taste of fish and find it a healthy and convenient meal option.

Regardless of the reason, the tradition of eating fish on Fridays is a reminder of the deep history and rich traditions of Christianity. It is a practice that continues to be meaningful to many people worldwide.


In summary, the tradition of Catholics eating fish on Fridays carries profound historical, religious, cultural, and communal significance. Despite evolving practices, it remains a symbol of faith, unity, and sacrifice within the Catholic community.
