You're a fool if you think men will not corrupt a theonomic government.
The Christian anarchist believes in Christian sovereignty, that Christians might be governed by Christ alone. We should have our own voluntary communities, by laws, committees, and elders. None beholden to any civil government.
Now, the governments of this world refuse to grant such sovereignty. So, we refuse as much participation in their system as possible, but obey certain ordinances that do not hinder us just to keep peace.
Christian anarchists envision sovereign Christian communities. Much like this one, but sovereign. Until that is possible, this is the closest the Christian anarchist vision can be realized.
