In the following period Landázuri Ricketts led during a period when priests rapidly developed
liberation theology and a theory of resistance to the military dictatorship under
Ricardo Perez Godoy who ruled Peru. Landázuri Ricketts responded to this with considerable support. In 1959, he said: In response, the entrenched
oligarchy called him and Bishop
Leonidas Proaño "Marxist manipulators." By comparison, in 1961, the
Rand Corporation, a
United States think tank, called him "moderate and able". He was also trying to ensure that the laity and nuns had considerable say in local decision-making. He became a major participant as Acting President in the 1968
Medellin Conference, more formally known as the
Second Episcopal Conference of Latin America. At its core, the Medellin Conference's final report, fully embraced Liberation Theology, which was "the church's decision to make a pastoral option for the poor." In 1970, in accordance with his
Franciscan ideals, and the "reforming spirit" of the times, Landázuri Ricketts left the Archbishop's palace and moved into a small house in a working-class area of Lima. Although he served on the
Pontifical Council for Interreligious Dialogue during the 1970s, his relationship with the Vatican soured after the ascension of
John Paul II. That pope believed that
liberation theology posed problems for Catholicism and was too involved in opposition to temporal political systems. Despite being an extremely respected prelate, Landázuri Ricketts had to accept more conservative
Opus Dei bishops and sympathisers being appointed in Peru during the 1980s and 1990s. ==Later life and death ==
