One needs to remember what bread, fish and water represent in Christianity.
Suffice it to say that water represents the mind, fish equal insights and bread spiritual sustenance. I could tell you, but you wouldn't believe me
For instance, "Fisher of men" does not mean someone dragging a line and a hook through the Dead Sea.
An superb reference is by the Episcopalian minister John A. Sanford, "The Kingdom Within". Dr. Sanford makes sense of Christianity. And solves the loaves and fishes problem for those who are stuck in a material world.
Good luck.
