What is the quadrilateral of meaning?

Andrew Fellows was appointed pastor of a church in Bradford, West Yorkshire in 1988 where he served for seven years. In 1995 his family moved to the English branch of L’Abri Fellowship, where they lived and worked for 21 years. From 2011 to 2016 Andrew was the chairman of L’Abri International. Now based in Cambridge, Andrew is the pastor of a newly formed church alongside his work of speaking and writing. He has a special interest in reaching sceptics and encouraging followers of Christ to develop the life of the mind so it includes the whole Gospel to the whole world with all of its implications. Here, Andrew answers questions from the talk "The Secular Age and the Struggle for Meaning", given at the 2024 European Leadership Forum.
