146. Of which miracles of feeding do the gospels relate?

All the gospels relate the miracle that Jesus fed five thousand people with five loaves and two fish (cf. e.g. Mark 6: 30- 44). Beyond that, the gospels of Matthew and Mark tell of the feeding of the four thousand (cf. Matthew 15: 32-39 and Mark 8: 1-9).
These miracles are reminders that God provided food (manna) during the journey of the people of Israel through the desert. Furthermore, these events are a reference to Holy Communion.
