I've been watching the developments between Israel and the Palestinians with deep pain and grief. While it is clear that Israel certainly has the right to defend itself, it is equally clear that the actions of both sides - Hamas and Israel - have been profoundly immoral and counter-productive to the ends either is supposedly seeking. The violence doesn't work and this situation is a prime example of that fact. It has been going on for decades and nothing is solved nor will it be until someone has the courage to stand and say, "Enough!"
That said, I want to address the issue of theology as we watch this. People often act as if theology is just a mind game that doesn't impact the real world except when talking about radical Islamists. I would say that theology - the way we understand God - is central to the way we behave and is critical in all of our interactions.
Regarding Israel, I have heard many Christians completely support their actions for one of two reasons - either saying that Israel is "The Chosen People" and basically can do whatever they want on "their land." Or... coming from some kind of dispensationalist stand that sees this all as a part of God's plan as revealed in prophecy and that peace in the Middle East is a bad thing.
Both are bad theology and result in the support of policies that are, let me say it flat out, sinful, immoral, and counter to the yearnings of God. Other theologies that we sometimes see at play are a deist view that God is in reality absent so our faith need not inform our actions at all or a theology commonly known as atheism which likewise allows for a variety of other kinds of moral structures for evaluating actions. Some have a theology that sees God as vengeful and concerned primarily about retribution. Finally there is a theology that sees mercy, justice, love, and community as the primary yearnings of God. Each would result in very different ways of evaluating the situation and in very different resulting actions.
For too long the church has neglected its role in teaching good, critical theology to church members, instead allowing them to be spoon fed garbage from popular authors with sensational visions of the future or allowed them to embrace some cultural theology that just reinforces whatever culture they happen to live in.
If the churches did and taught good, critical theology, we'd be standing up shouting for Israel and Hamas to stand down and to seriously work towards a permanent solution to the conflict and we would be using all of the leverage we have to that end.
