The other day I was walking across the parking lot at work when the bell in the large, classical Presbyterian church rang. For a moment I thought about what it would be like to live in a country where church and state are united and the church is not compromised. I felt at ease for a second thinking of Christians, real Christians running the nation. I felt like I had nothing to fear.
After a brief moment the feeling passed. The Presbyterian church the bell rang from is part of a liberal denomination and so it is very likely that it teaches a hollowed out Christianity. The unity of Church and state has never left Church unscathed, she soon becomes polluted by men seeking power not Christ. Sin has so corrupted man that we can never achieve peace like that while man rules (sorry, no post-millennialism). Peace on earth like that can only come when Christ rules the nations with a rod of iron. What I got a fleeting glimpse of was the New Heavens and New Earth. No man-made institution.
