Pontifical Academy of Sciences The academy brings together eminent scientists and professors from all parts of the world to explore contemporary issues at the nexus of science and faith. This learned society is one of two modern reincarnations of the Accademia dei Lincei, a society of 17th century scholars that once numbered Galileo Galilei among its members. Galileo's portrait rests atop the desk of the chancellor of the academy. The website has links to the papers and proceedings of the academy, most of which are in English.
Pontifical Academy of Social Sciences This academy is under the same administration as the Academy of Sciences and similarly explores research and scholarship at the nexus of social issues and faith.

In 2012 the academy published Universal Rights in a World of Diversity - The Case of Religious Freedom, the proceedings of its plenary meeting of the year before.
Pontifical Council for Culture Blessed John Paul II founded this council in 1982 with the purpose of "establishing dialogue between the Church and the cultures of our time, so that they could open themselves up to the Christian faith, creator of culture and source of science, letters and the arts." Cardinal Ravasi, the president of the council, recently founded a forum called The Courtyard of the Gentiles for a cultural dialogue with the unchurched and non-believers. The website of the council has some useful links and also appears to be still in development, as you can tell from the untitled catalogue of the electronic journal, Cultures and Faith, linked under The Review in Tools.
Pontifical Council for Inter-religious Dialogue This very important council was founded in 1964 by Pope Paul VI.

The webpage is part of the Vatican site and has links to major addresses of the council and its members.
Pontifical Council for Justice and Peace This body of scholars is housed at San Callisto in Trastevere, which is an extraterritorial possession of the Vatican.
