I've worshipped alongside both Republicans and Democrats. I've sat across the table from and had political discussions with Christian conservatives and progressives. I've even conversed with a sitting senator who is a devout Christian and a tea party aligned conservative. I find it impossible to deny that any of them are Christian. Both sides want what is best for the country, they just disagree on how to get there.
Christians on the right believe that poverty is the result of a lack of motivation and that if we ended the safety net programs that are allowing the poor to live off of charity, the threat of starvation would motivate them to better themselves. They also see taxes and government regulation as chains that constrain businesses. They believe that if we unburdened those business by cutting taxes and getting rid of some of those chains of regulation, they could operate more efficiently and become stronger engines in the economy, leading to more job growth and increased opportunity. Thus they seek to cut social programs as well taxes and government regulation. In this way, conservatives seek to address the issue of poverty
Those on the left see poverty as a systemic, structural problem, the result of a socio-economic system that unequally distributes opportunity in an unjust way. They see the path towards ending poverty as one wherein we make changes to the system so that opportunity is more justly distributed; those needing more help get more help and those needing less get less. They see taxes and government regulation as tools that can be utilized to fix some of these systemic problems and help guide us towards a more just society. In that way, progressives tend to see government regulation and taxation as useful tools in creating the kind of just society they wish we had. In this way, progressives seek to address the issue of poverty.
Ultimately, both seek the same thing. They seek an end to poverty and a stronger economy. They just seek it in different ways.
Obviously, I align myself with one of those camps and think the others are completely wrong. But that's no excuse for me to pretend that my tea party brothers in Christ are any less Christian than I am. Wrong? Yes. Deceived? Yes. Missing the point on a lot of issues? Yes. But not Christian? heck no! I have and will continue to gladly worship alongside them and work with them in the areas we do agree on.
*I recognize this is a gross oversimplification and that there are may different nuances I could have gone into. I stuck to poverty as an example, but ultimately the progressive and conservative vision for America really are quite different. I realize I'm only scratching the surface.
