The Society for Promoting Christian Knowledge (SPCK) is a UK-based Christian charity (registered number 231144). Founded in 1698 by Thomas Bray, it has worked for over 300 years to increase awareness of the Christian faith in the UK and across the world. The SPCK is the oldest Anglican mission organisation in the world, though it is now more ecumenical in outlook and publishes books for a wide range of Christian denominations. It is currently the leading publisher of Christian books in the United Kingdom and the third oldest independent publisher in the UK.
