1. There have been many many religious conscientious objectors over the course of history. I believe the Quakers are the strongest anti military religion, but even there, if someone chose to go to war im sure they don't disfellowship. In my current church, there are people who have been in the military and people whose sons are in the military, and there are also many people who would NEVER support war and definitely not fight in one. The thing is, most churches allow a persons conscience to make this decision, but do not punish people for going with their own conscience. The same goes for number 4., generally,actually as well. The church is there to guide people, not condemn. Their sin is between them and God,for the most part.
2. Refuse to get involved with politics....personally I think this is stupid. I think it's good for the church as a whole not to get involved with politics, but for individual members, I believe politics is very important. For any church to ban its members from being political is taking away a huge freedom that should be a human right. I wonder if witnesses voted in Germany in the 30's, would Hitler have ever won that election? 3. Churches talk about the kingdom all the time, but usually its with the application 'let your will take place'... We know gods will is that we take care of the weak and poor. Most churches try to help spread Gods kingdom now, by helping make the world a better place.
