Instead of discussing the differences between Mormons and Christians - Mormons are not Christians - I want to draw to your attention a well-written post on Christianity and politics by Nathan Busenitz of Pulpit Magazine. The post is subtitled "Bringing in the Kingdom one vote at a time?" and it is worth a read.
A casual perusal of this blog quickly reveals that I enjoy discussing politics and have strong political opinions. I do not think it sin for a Christian to hold political office, but I also do not believe that holding political office is the means by which God will bring righteousness to this or any nation. In his post Busenitz asks the questions:
Is it really the church’s mission, or even her responsibility, to gain political dominance? Should we preoccupy ourselves with congressional hearings, presidential campaigns, and economic plans? Do we need to form committees and coalitions who will raise millions of dollars to protect the Ten Commandments and vigilantly stand against any advance by the “immoral minority”?
No...Matthew 28:18-20 gives us the mission, or commission, with which we should be primarily concerned. It is hardly political in nature.
American Christians...must remember that our allegiance is first to God and only second to our government. Our primary concern then should be in saving souls rather than gaining votes. Rather than being consumed with political debates, we should be consumed with our responsibility as Christ’s ambassadors. These are the efforts and activities that have eternal value. And while we preoccupy ourselves with the spiritual rather than the political, we can rest in knowing that He is sovereign over the governments and affairs of this world. (Emphasis added)
I like politics. I enjoy debating political issues. I enjoy exercising my American rights and privileges, but I fear that far too many Christians equate political activism with Biblical orthodoxy. Being a social, fiscal conservative Republican is not synonymous with being a Christian.
