In case you haven't guessed yet, I am a Christian but I view Christianity not as a religion but as a personal faith, a relationship, between a human being and God. How can a nation possibly be "Christian?" One of the main concerns that I have with people wanting America to become a Christian nation is that we as voters begin to vote based on religion rather than competency. We begin to ask ourselves questions like, "Could I ever vote for a Mormon?" for instance.
In my heart, I truly believe that we cannot allow our religious beliefs to cloud our judgement when it comes to voting. The modern church seems to have become more focused on getting a Christian into office than we are about being a Christian at the office. I think voting should be based much more on values than religion, and yes, there really is a difference. If I vote my values, I can vote for an someone of any belief system or even an atheist, if they value the things I value in a nation. Someone having to believe the world is 6,000 years old is really not a very important concern to me when it comes to running my country.
When it comes time to vote for a new pastor at my church I will vote based on theological beliefs, when it comes to voting for a president I will vote for who I think is the best person for the job. As Christians, when we fight to have a Christian nation, then we are devaluing every other faith system out there, which ironically makes us just like the system we were fleeing to come here in the first place. If Christianity is so wonderful, we should not need to legislate it, we should simply put it on display for the world to see for themselves.
