For a some time the words "O Segnore, fa di me uno strumento della tua pace" (O Lord, make me an instrument of your peace) have lain at the back of me mind, and they have some times taken a passionate voice when I happened to be in a church with nobody around! But I'd forgotten where the words came from.
I've just discovered that they are by St Francis of Assisi. There's an English translations of the full poem, accompanied by a gentle flowing tune ... like a lullaby. But Francis was surely no baby: you have to be tough to revolutionise the church as he did!
I'm wondering where my tune came from.
