It is night while they are fishing, and in John s well-worked symbol of light, Jesus appears at the shore, it was already dawn, and now Jesus would do some more fishing for His friends. We will see Peter standing with Jesus again. There is a charcoal fire there and some fish and bread cooking. Easter is happening at dawn for those who had gone back into their old ways of seeing themselves in the dark. There are some consequences for Peter and the others, though.
Easter is also a future event.
It does remember an event, it does take place in the present, but its movement is always from death to life, from dark to light, from then to when. Peter is invited to follow Jesus in feeding the future-followers of Jesus. Again Jesus does not give Peter exact descriptions of what this feeding might entail. He doesn t give Peter a map, but rather an indication of what it is going to cost him. The Gospel ends with the usual words to Peter and to us, Follow me.
