What Is the Catechism? What Are the Questions It's Not Answering?

The catechism is meant as a brief summary document. It's its not meant to spell out the church's thought in exhaustive detail. Just because some catholics espouses anarchy doesn't mean their espousing a version of anarchism that is compatible with the teaching of the church. The way to do that would be to elect people who will be willing to scrap our current constitution or make other arrangements for an anarcho capitalism. And if people wanted, for example, to institute anarco capitalism, you could do that here in the united states.
