Evangelicalism and National Idolatry

Over at Patheos, Timothy Dalrymple is running a forum on this subject.  He is asking experts from the evangelical community to reflect on these questions:

1.  When does patriotism pass over into idolatry?  How do we define America-worship?  What is the difference between loving, honoring, and worshiping America?

2.  What are the healthy and unhealthy ways of relating politics and religion?

3.  What is the evidence that politically conservative evangelicals have become guilty of America-worship and wrongly relating their politics to their faith?

If I get the time, I would like to take a crack at these questions here at The Way of Improvement Leads Home. In the meantime, how would you answer any or all of these questions?
