Today, 6th August, is the Feast of the Transfiguration on the church’s calendar. But in the history of humankind, this day is remembered for the 1945 detonation of the atom bomb over the city of Hiroshima in Japan.

Today I re-read Paul Tillich’s essay ‘The Shaking of the Foundations’ in which he explores humankind’s ability to use this terrible destructive power, now come of age in the twentieth century. The challenge for the human race is how to come to terms with what we now know of our power to annihilate life on earth. How will we live with ourselves, can we do it?
