Lesslie Newbigin: from Liberal to Evangelical. A controversial viewpoint?

I was recently reading an article on Christian Socialist Movement theology section which I found fascinating - so I thought I'd share it. It talks about the famous missioner Lesslie Newbigin and how his Christian journey was shaped, partially by SCM and the relationship it had with CU in the past. It got me thinking: what can we learn from yesterday's problems (and mistakes, even)? What is at the heart of mission? Do we recognise others as Christians? Is this the desirable goal? Are we aiming to be Liberal/Conservative or are we aiming to be Christians? Are the distinctions and indentities even necessary and in a society which is radically disengaged with Christianity? What is the gospel?
