The Theologische Realenzyklopädie (TRE) is a German encyclopedia of theology and religious studies. It contains some 2000 articles in 36 volumes. The first installment was published in 1977, the last in 2004.
Genesis and editors
The Theologische Realenzyklopädie is published by Walter de Gruyter and continues the nineteenth-century tradition of specialized encyclopedias, specifically that of the Realenzyklopädie für protestantische Theologie und Kirche, published in Leipzig between 1896 and 1913. But in contrast to the latter, the TRE treats its subjects in an ecumenical fashion.
The TRE was edited by fourteen main editors. The primary editor was the bishop and church historian Gerhard Müller of the Evangelical Lutheran Church in Brunswick. Until volume 12 his fellow main editor was Gerhard Krause, professor of theology at the University of Bonn.
