Jesus asked the disciples to see what resources the people had. All they came up with were five loaves and two fish. Jesus took them, broke them into pieces, and when the crowd had eaten, there were twelve baskets of leftovers. I think that's a metaphor for the dialogical process of faith.
We gather, offer the loaves and fishes of our lives' experiences and mysteries, and there is always enough food and leftovers for us to keep going and growing in faith.
