Third, the concern to ground what we say in the Scriptures of our traditions shows a desire to meet each other not ‘at the margins’ of our historic identities but speaking from what is central and authoritative for us. Here, however, it is especially important to acknowledge that the Qur’an’s role in Islam is not the same as that of the Bible in Christianity; Christians understand the primary location of God’s revealing Word to be the history of God’s people and above all the history of Jesus Christ, whom we acknowledge as the Word made flesh, to which the Bible is the authoritative and irreplaceable witness. For the Muslim, as we understand it, the Word is supremely communicated in what Mohammed is commanded to recite. But for both faiths, scripture provides the basic tools for speaking of God and it is in attending to how we use our holy texts that we often discover most truly the nature of each other’s faith.
Having made the crucial point often missed by secular commentators and Muslim critics alike (that we are not "people of the Book", we are "people of the Word"), he then he goes on to make a breathtaking explanation of the Trinity:
Muslims see the belief that God could have a son as suggesting that God is somehow limited as we are limited, bound to physical processes and needing the co-operation of others. How can such a God be truly free and sovereign – qualities both Christianity and Islam claim to affirm, for we know that God is able to bring the world into being by his word alone?
Here it is important to state unequivocally that the association of any other being with God is expressly rejected by the Christian theological tradition. Since the earliest Councils of the Church, Christian thinkers sought to clarify how, when we speak of the Father ‘begetting’ the Son, we must put out of our minds any suggestion that this is a physical thing, a process or event like the processes and events that happen in the world. They insisted that the name ‘God’ is not the name of a person like a human person, a limited being with a father and mother and a place that they inhabit within the world. ‘God’ is the name of a kind of life, a ‘nature’ or essence – eternal and self-sufficient life, always active, needing nothing. But that life is lived, so Christians have always held, eternally and simultaneously as three interrelated agencies are made known to us in the history of God's revelation to the Hebrew people and in the life of Jesus and what flows from it. God is at once the source of divine life, the expression of that life and the active power that communicates that life. This takes us at once into consideration of the Trinitarian language used by Christians to speak of God. We recognise that this is difficult,
sometimes offensive, to Muslims; but it is all the more important for the sake of open and careful dialogue that we try to clarify what we do and do not mean by it, and so trust that what follows will be read in this spirit.
In human language, in the light of what our Scripture says, we speak of “Father, Son and Holy Spirit”, but we do not mean one God with two beings alongside him, or three gods of limited power. So there is indeed one God, the Living and Self-subsistent, associated with no other; but what God is and does is not different from the life which is eternally and simultaneously the threefold pattern of life: source and expression and sharing. Since God's life is always an intelligent, purposeful and loving life, it is possible to think of each of these dimensions of divine life as, in important ways, like a centre of mind and love, a person; but this does not mean that God ‘contains’ three different individuals, separate from each other as human individuals are.
Christians believe that in a mysterious manner we have a limited share in the characteristics of divine life. Through the death and rising to life of Jesus, God takes away our evildoing and our guilt, he forgives us and sets us free. And our Scriptures go on to say that he breathes new life into us, as he breathed life into Adam at the first, so that God’s spirit is alive in us. The presence and action of the Holy Spirit is thus God in his action of sharing life with us. As we become mature in our new life, our lives become closer and closer (so we pray and hope) to the central and perfect expression of divine life, the Word whom we encounter in Jesus – though we never become simply equal to him. And because Jesus prayed to the source of his life as ‘Father’, we call the eternal and perfect expression of God's life not only the Word but also the ‘Son’. We pray to the source of divine life in the way that Jesus taught us, and we say ‘Father’ to this divine reality. And in
calling the eternal word the ‘Son’ of God, we remind ourselves that he is in no way different in nature from the Father: there is only one divine nature and reality.
Finally, he powerfully deconstructs the argument of the religious fanatic in one paragraph:
To believe in an absolute religious truth is to believe that the object of our belief is not vulnerable to the contingencies of human history: God's mind and character cannot be changed by what happens here in the world. Thus an apparent defeat in the world for our belief cannot be definitive; God does not fail just because we fail to persuade others or because our communities fail to win some kind of power. If we were to believe that our failure is a failure or defeat for God, then the temptation will be to seek for any means possible to avoid such an outcome. But that way lies terrorism and religious war and persecution. The idea that any action, however extreme or disruptive or even murderous, is justified if it averts failure or defeat for a particular belief or a particular religious group is not really consistent with the conviction that our failure does not mean God's failure. Indeed, it reveals a fundamental lack of conviction in the eternity and sufficiency of the object of faith.
Religious violence suggests an underlying religious insecurity.
One question, however, on reading this last paragraph - I wonder if we are seeing here mental preparations for the Worst Case Scenario at Lambeth...
