Emitte lucem tuam has very kindly posted a short summary of my talk at St Patrick' Soho Square the other day. See: A challenge to the culture.
As I mentioned, the full version will go on the St Patrick' parish website in due course and I will let you know when this happens.
(BTW - I forgot to bring my camera on Wednesday. If anyone did take any photographs of the talk, please email them to the Catholic Herald (email@example.com) marked for the attention of Anna Arco who might be interested.)
