I've wondered about this for a while now and have a lot of questions with no clear answers.
Most American Christians are right of center because of the myopic (in my view) focus on two hot-button morality issues (abortion and homosexuality). But how should a Christian respond:
*to war? Is the Iraq war just? Is the war in Afghanistan just? Is war ever "just"? What should a Christian's response to war be? Is pacifism Biblically supported?
*to economic hardships? We all know it's a believer's job to help the poor and downtrodden; the widows and orphans. Do we? If we do, how often is it only a gift of our money but not our time and effort.
How should this translate in a political context? Should the government also assist in the care of its society? If it should, to what extent should the government help? how big should the "social safety net" be? On the other hand, if we do think government should have a social agenda, does this (subconsciously or otherwise) cause us to abandon our own personal responsibility because we (subconsciously or otherwise) think that the government is "taking care of it"?
*to wealth? What should our response be to wealth? We see the mantra "the rich are getting richer and the poor are getting poorer". Part of one party's answer is to eliminate tax cuts to the rich. The other party believes in "trickle down economics". Is there an aspect of class envy here? Or is an injustice? If so, how should it be corrected?
*to abortion? OK, fine, it's wrong. But is an outright ban the answer? It may very well be; but even if it is, is it worth the time and effort we Christians have historically put into this issue? If that time was spent spreading the gospel, or caring for the poor and downtrodden, wouldn't the Kingdom of God be furthered more?
Also, we Christians are good about crisis pregnancies, but what about help for new mothers?
Politically, why do we give so much attention to the pro-life/pro-choice views of our leaders? Why has it become a litmus test for Christians? Other than Bush's partial birth initiative, has there been any action other than simple lip-service by a pro-life politician? We hear so often that we need to get a conservative leader in the white house because of upcoming vacancies in the supreme court. When push comes to shove, will Roe v. Wade ever be overturned?
*to homosexuality? Does it really matter that homosexuals are getting married? Most Christians can agree that homosexuality is anti-Biblical, however, I have not heard one cogent non-theological argument against gay marriage. Doesn't there need to be an argument that will appeal to non-Christians also? Do non-Christians care that the Bible says homosexuality is wrong? Should they? Do we need a broader political reason? If not, why?
Again, I have some opinions on these issues (some of which may have leaked out because of my writing). But I honestly do have questions on these. Questions, that I don't think have a clear answer; and answers that cannot be answered by one political party or another.
