Rowan Williams’ enjoyable little book Being Disciples (SPCK) has a whole chapter on daily bread which is interesting.
He talks about the need for bread in the wider context of our humanity and being those who need to receive as well as give.
He also notes ‘the odd Greek word that is used in the Gospels for “daily bread” whose exact meaning has proved elusive’ but it could have meant in the original Aramaic that Jesus
was telling us to pray for the gifts of the coming kingdom to be received in the present … The need, the hunger, we must learn to express is a need not simply for sustenance but for God’s future. What we need is the new creation, the bread that comes down from heaven and gives life to the world’ (p42)Rowan Williams Being disciples p 42.
