Theology is man's attempt to bring meaning into situation, to people or within history. This is why theology has been so diverse, as it has spoken in different ways and for different reasons.
Man seeks to understand life, this is what the natural sciences are about, but theology seeks to connect the real world to God. What is the real world?
The real world could be historical events that bring disappointment or despair. It could be a disorientation to life by a people, or it could be a people's situation. Theology can be systemized through themes of Scripture, but today's need is much broader than any of these.
Althougth there are still peoples that need hope in their specific context, there is a real need to univeralize the hisorical situation and mankind today. A universalization is akin to using our globalization for the benefit of mankind, to help bring meaning within a broader context and give more of a broader vision or perspective, so that the economic will not drive meaning and relationships.
Today Black Theology, Liberration Theology, Feminist Theology, Biblical Theology, Dogmatic Theology will not do. Texts and Cultures must be unified. There should not be a distinction of theology based on a ethnic group, such as the Jew, or the "Gentile". Theology should have a wide, and inclusive grasp that goes beyond specifics. We need a "Globalized Faith", where no one faith is primary, while allowing the diverse ways of understanding and worshipping God can be affirmed. Therefore, such universal needs of man must be recognized and addressed. I think that a theology based on the Quadralateral, psychology, history, and philosophy would meet this need.
For the "New Covenant" promises that they will all know me from the least to the greatest and no one will have to teach anyone to know the Lord for they will all know me"
