I worry that Unitarnianism in the West had a parasitic relationship with conservative religion. Where conservative religion is strong, as in the United States, Unitarianism does well scooping up a certain percentage who rebel against conservative religion, because it is refreshingly different. But where secularism is strong, as in the United Kingdom, it fails utterly as a powerful religious force. Unitarianism too often seeks to answer the question - why belong to this faith community as opposed to another faith commmunity? But too little seeks to answer the question - why belong to any faith community at all?
We have no idea how faith development works as a transition from unchurched to liberal church. The path of unchurched to conservative church is well documented. The path from conservative church to liberal church is well documented. But how does one go from unchurched to liberal church? It seems that few people do that. Are we prepared to accept the fact that we need conservative religion to define ourselves and to grow?
What is required is a strong missional liberalism that provides something more solid than secularism, as opposed to something less solid than conservativism. This will require a change in our culture and our theology if we are to have any hope of reaching the unchurched.
