Why Catholics consider fish S meat?

The reason for this confusion might stem from the tradition of abstaining from eating meat on Fridays during Lent. This tradition dates back to the early Church and was a way to honor the sacrifice of Jesus Christ, who died on a Friday.

However, the Church never considered fish to be meat. This is because fish are cold-blooded and do not have red blood. Historically, this was considered a key characteristic of meat.

Therefore, while Catholics traditionally abstain from eating meat on Fridays during Lent, fish has always been permitted and is considered a type of seafood.
