Leo Scheffczyk

Leo Scheffczyk (; 21 February 1920 – 8 December 2005) was a German cardinal and theologian. He was a long-time theologian at the Congregation for the Doctrine of the Faith and one of the strongest advocates for orthodoxy during the long pontificate of John Paul II. During the 1980s and 1990s, he severely criticized some of his former students, e.g. Leonardo Boff, who advocated a Marxist version of liberation theology. Scheffczyk likely played a major role in drafting the most controversial documents, such as ''Ordinatio sacerdotalis'' and ''Ad tuendam fidem''. He was made a cardinal in 2001. He was regarded as an important thinker in late twentieth-century Catholicism. Provided by Wikipedia
