On this most patriotic of holidays, it's worth asking the question, "What should the relationship between church and state look like?" Consider this quote from German scholar, Theo Sorg,
"The New Testament knows nothing of a Christian state, but it knows of Christians who profess their Lord in public life and in their political responsibility, and who make every effort to realize symbolically something of his good rule. It is not they themselves who create the coming reign of peace; God alone will bring it about. But they have this goal before them and can therefore seek to bring about peace wherever and however that is possible, in every weakness and fallibility, but nevertheless with the breath of Christian patience."
From Theo Sorg, "Die Bibel zum Thema Frieden," Theologische Beitrage (1982): 264-265. Quoted by Helmut W. Ziefle in Modern Theological German: A Reader and Dictionary (Grand Rapids: Baker Books, 1997), 243. My translation.
