"The Puritans agreed that Jesus Christ is Lord of the whole of life including the things of this age. So they were true secularists, being openly theistic secularists." In this lecture, David Holloway argues that we have a public theology deficit - the world has changed and presents new challenges that Christians have failed to think through. At the time of the Reformation and during the Puritan era, Christians had a deep concern for the total welfare of their fellow men. But this is something that seems to have been lost now. This study describes the current situation for the church in our culture and begins to suggest ways in which we might work to re-establish the Christian faith. David Holloway is Vicar of Jesmond, Newcastle upon Tyne. Having previously worked in the Sudan, Leeds and on the staff of Wycliffe Hall Theological College, Oxford, he was for many years a member of the General Synod of the Church of England and on its Board for Social Responsibility and Standing Committee. He is also a Trustee of Reform and The Christian Institute.
