God, the Future of Man focuses on religion and secularisation, viewed from various vantage points: secularisation and God-talk; secularisation and the church’s liturgy; secularisation and the church’s new self-understanding; and, finally, secularisation and the future of humankind on earth in light of the eschaton (church and social politics). These thought-provoking reflections are presented against the backdrop of Schillebeeckx’s hermeneutic premises. In the concluding chapter his reflections on secularisation culminate in a God concept that can function fruitfully in a modern culture that assigns the future pride of place: God as the future of humankind. Written in a period pregnant with Cultural Revolution and religious change, the book foregrounds the pivotal issue of secularisation in a thought-provoking way. With feverish urgency he reflects on various forms of religiosity in the modern world. His contribution to the debate could just as well have been written today.
