The Bible does not have a single or simple explanation for fish eating. It depends on the context, the interpretation, and the personal choice of each individual. In the Old Testament, God gave dietary laws to the Israelites that forbade them from eating any sea creature that did not have fins or scales. In the New Testament, Jesus declared that all foods are clean and that what matters is not what goes into the mouth but what comes out of it. He also ate fish himself and used fish to feed the crowds and to symbolize his resurrection. Some Catholics avoid eating meat on Fridays during Lent, but they can eat fish, eggs, dairy products, and other seafood. In Eastern Orthodoxy eggs, dairy products, and meat is forbidden during Lent but fish is allowed. Some Jews also fast on several days throughout the year and abstain from all food and drink, but they can eat fish on other days when they observe a partial fast.
