This connected fishing with spreading the Gospel.

Fish appear repeatedly in Jesus’ ministry:
- Feeding the 5,000 with five loaves and two fish
- Feeding the 4,000
- The miraculous catch of fish (Luke 5)
- Jesus cooking fish after His resurrection (John 21)
These moments associate fish with provision, abundance, and divine power.
3. Fish and Baptism Symbolism
Water represents cleansing and new life in Christianity. Fish, which live in water, became symbolic of believers who are reborn through baptism.
