Sacramentum Mundi: An Encyclopedia of Theology (6 vols.)

Sacramentum Mundi is a six volume English reference work in Catholic Theology, edited (in 1968-1970) by Karl Rahner—one of the main Catholic theologians of the 20th century. It is an attempt to formulate present-day developments of the understanding of the faith, basing itself on modem theological investigations of the key themes of the theological disciplines, in the hope that they will thus be fruitful for personal reflection in faith and in practice. The developments in question may be characterized as a thinking which takes fully into account the conditions of past and present historical growth in the understanding of faith. It has therefore a strongly marked orientation to the future—its historical dimension—and is also marked by its openness for the other Christian churches, the non-Christian religions and for the world in general—its social dimension.
