Why is the fish a Christian symbol?
When Jesus called Peter and Andrew, He told them he would make them “fishers of men” (see Matthew 4:19-22). Early Christians embraced that title with the fish symbol. Also the Greek word for fish (icquv~) came to stand for Ihsou`~ Cristo~ qeou` uiou` sovthr, which means Jesus Christ God’s Son Savior.
Why do we have fish symbols in our worship and our homes?
We have this symbol in our worship and homes to remind us who Jesus is (Messiah, God the Son) and why He came (to be our Savior). The fish symbol also reminds us of our mission to be fishers of men.
What does the Bible say about this symbol?
The Bible clearly teaches us who Jesus is and why He came. The Bible also teaches that we are fishers of men (see above). The Bible refers to the church as a boat (see Genesis 6-9, 1 Peter 3:18-22). The Church has used Luke 5:1-11 as an example of the church’s life and mission. The boat is the church, the nets are the casting of the Word, and the fish is the increase God brings to our efforts in His kingdom.

Object Lesson
Show a fish net. Tell how the disciples were fishermen who cast nets to catch fish. Jesus provided them with a great catch. We cast the Word of God and the Holy Spirit uses the Word to bring others into the boat of God’s church, giving them eternal life.
Prayer
Lord of harvest, great and kind, rouse to action heart and mind; Let the gath’ring nations all see Your light and heed Your call. Amen.
