This book arises out of the need which has been felt for what might be called A Primer of Christianity. It is especially for those who are conscious of the great importance today of the scientific outlook and want to know how Christian faith and Christian theology can claim to be true when measured by scientific standards. Richardson shows that there can be and does exist a real science of theology working on the data provided by the historical facts concerning Christ and the Church, and that it has reached real and important results. He outlines what these are and shows how they point the way to the next step, which can only be taken by each person for himself–personal faith.
