What would it look like if it were?

Adam Lee points out:

In reality, there’s such a huge diversity of opinion among self-professed Christians past and present that the term “Christian values” could mean almost anything.

Christians have been communists and socialists (including Francis Bellamy, the author of the Pledge of Allegiance); Christians have supported empire and dictatorship (including Mussolini, who made Catholicism the official state religion of fascist Italy). Christians have advocated positions across the political spectrum, from environmental preservation to environmental destruction, from pacifism to just war to open advocacy of genocide, from civil rights to segregation and slavery.

He discusses what forms of government are sanctioned in the Bible and points out that democracy is nowhere mentioned. Then he provides a lesson in constitutional history, observing that the constitution is a “godless” document.

… it’s easy to see just how unique, unusual, even unprecedented the Constitution is. The United States of America was the first modern republic that was created on the foundation of reason, without seeking blessings from a god, without imploring divine assistance or invoking divine favor. And, as I said, this fact was not overlooked when the Constitution was being debated. Very much to the contrary, the religious right of the founding generation angrily attacked it, warning that ratifying this godless document as-is would spell doom for the nation.

Tom Ehrich answers the same question from a very different perspective:

If we were a genuinely Christian nation, we would be gathering the harvest of this abundant land and sharing it with the hungry of our own land and of many lands. We would forgive our enemies, speak truth to power and go forth to serve and to sacrifice, not to rule.

We would stand with the poor when predators circled around them. We would stand with sinners when the self-righteous picked up stones. We would join hands with nonconformists and strangers.

We would become God’s beacon to the nations. And when the tired and poor followed that light to our borders, we would greet them with open arms and make room for them in our communities.

That’s what Jesus did, and that is what it would mean to be a Christian nation.
