It's widely recognised that popular atheism is changing fast. It's moving into a more constructive phase after the attacks on religion, inspired by scientism, that characterised the first decade of the new millennium. One of the most interesting new movements is the Sunday Assembly, sometimes called the "atheist church" - though the founders are not keen on that title as it suggests they are against rather than for something. It began about 3 years ago and, in that short time, has spawned over 70 congregations around the world, particularly in the UK and US. In this Science Set Free podcast, Rupert Sheldrake and Mark Vernon discuss this new development, after Mark made a radio programme for the BBC on the Sunday Assembly. They ask how atheism is changing; how it is embracing dimensions of life such as the ecstatic that have been quite taboo in atheist circles; and what this means for our time.
