Originally published by the Paulist Press in 1978, this book attempts to elaborate a foundational theology that could interpret the experience of Christian life in all of its social complexity. Father Gelpi reflects both on his personal experience as well as the principal texts of the Christian religion. He examines the American philosophical contributions of Edwards, Peirce, James, Dewey, Santayana, and Whitehead and their contribution to our Christian heritage. Co-published with the College Theology Society as part of its Reprints in Religion Series.
