The National Evangelical Anglican Congress which took place at Keele University in April 1967 is widely acknowledged as a major watershed for the evangelical movement in the Church of England. This paper offers a fresh analysis of the event, based on detailed archival research. It argues that there was a decisive attitudinal shift at the congress, driven especially by the younger generation – from piety to policy, conservatism to radicalism, homogeneity to diversity, and exclusivism to ecumenism. It shows how in these four areas the Keele Congress established a new agenda for Anglican evangelicalism, a legacy which still continues today.
