Lack of government is anarchism, right?
not right, in fact.
anarchism, by definition, does not exist (you cant put a name on something that rejects stricture and conformity, once you tell an anarchist that s/he subscribes to anarchism, s/he will reject it instantly [and potentially spray-paint on your garage]). anarchists, however, exist and they are not bound into a group because that would encompass the entirety of humanity. everyone has a different sized anarchist living inside of them because it's a product of being a primate with a large brain. our group mentality and tribal preoccupation has to be countered by something and the desire to be free is what pulls us to be individuals among many. this is part of why we can't get our large numbered groups to work as seamlessly as ants or bees. (and this is a good thing)
anarchy (as someone else pointed out) is a state of being devoid of unnecessary hierarchies. anarchists reject unnecessary hierarchies. government can interfere with anarchy, or your garbage collection service can interfere with anarchy. an anarchist rejects the pope the same way as s/he rejects a drug dealer, or a school teacher, or an astrophysicist - if they stand in the way of hir freedom.
was christ preaching an anarchist message: no.
was christ anti-government: no.
was christ a pacifist: no.
did christ teach non-violent direct action: yes (cleverly, indeed).
was christ anti-roman: yes.
i personally feel that the term "christian" and the term "anarchist" are simply incompatible. "Christian anarchism is the belief that there is only one source of authority to which Christians are ultimately answerable, the authority of God as embodied in the teachings of Jesus." this clearly means that xian anarchists are willing to reject all authority figures besides one, they will only allow one boot to be on their throats. as i stated before, everyone is an anarchist to a different degree (every time you run a stop light because it's four in the morning and it just hasn't changed for five straight minutes, but nobody's coming from ANY direction - you become an anarchist for as long as it takes to get through the light.), but the active acceptance of christ as an authority figure is a rejection of anarchy.
christians are christians, anarchists are anarchists. some anarchists might be christians and some christians might be anarchist. some anarchists like grapefruit, some christians like grapefruit. that doesnt make it a movement.
however, christians as pacifists makes plenty of sense. they have to follow a more strict "do as i say not as i do" policy when reading the new testament (cant go throw a tantrum every time someone decides to have a temple garage sale), but it is certainly feasible. the only hang up is that christians who expect god to do their fighting for them are not pacifists, they are simply underlings. saying "my dad can beat up your dad" is not the same thing as saying "nobody needs to beat up anyone, let's just talk about it." if you walk away from non-violence with the image of your opponent burning in eternal damnation you have not been pacifist, you've been passive aggressive. but i think, by and large, the above grapefruit sequence could be applied to pacifism too - the man's not preaching it, but he's not preaching against it.
