An essay in "liturgical theology", this book is in fact a study in biblical theology which seeks to provide a firm basis for the eucharistic liturgy in the great Judaeo-Christian tradition represented by the Scriptures. From the insights which came to him within the brotherhood of Taize in France, Max Thurian believes that the real presence of Christ must be studied within the "liturgical action" and not isolated as a separate theological problem. In the Reformed tradition of Taize he turns, therefore, to a study of the Scriptures and opens the Scriptural meaning of the Eucharistic memorial as seen in the Old and New Testaments.
