Our three theologians grapple with the doctrine of the Trinity and its relation to the cross. In Mark’s gospel, Jesus cries out on the cross, “My God, my God, why have you forsaken me?” (Mark 15:34). What does this cry of dereliction tell us about the relationship between Father, Son and Holy Spirit? Can God suffer? Can he change? Is God’s action sometimes ‘hidden’, as Pascal suggested? Graham, Mike, and Jane go on to consider the relationship between prayer and time and the nature of human participation in the work of God. Can we pray for things that have already happened? Can we pray for our loved ones who have died?
