Karl Barth was a way for theology to address modernity's criticism. While modernity needs the transcendent, the transcendent needs the grounding of modernity's critique. Today's post-modernity brings us to experiential faith, which is not grounded at all.
What do I mean by this? Post-modernity has struggled to find a reason for the hope of Christian faith. Stanley Grenz grounded his understanding in the community of God. The "redeemed" were to exemplify Christ's life. The basis of "fact" was developed upon the Trinity. But, in actuality it is another type of existentialism, as it applies to the organizational structure of the Church. And the Trinity itself is a philosophical understanding of God. It is not a fact, but a representation of fact.
Fact is based on science and the historical and social sciences should give new insight into what happened in the development of Christian faith, which was grounded within a Jewish context. Judiasm itself must be understood. And then, Judiasm must be understood within the historical development of World Religions, or Traditions, which are representative of cultures.
Civilizations are representative of cultures, which are understood by the laws, values and customs that define them. And people are constructed within these contexts. Understanding other cultures is necessary in international relations, diplomacy and the globalized market. Hopefully, international law will develop a format for businesses to be boundaried by proper behavior within the global market and economy.
