SEDOS (Service of Documentation and Study on Global Mission) is a forum open to Institutes of Consecrated Life, which commit themselves to deepening their understanding of global mission. It encourages research and disseminates information through its Bulletin and Homepage, the annual SEDOS Residential Seminar (beginning of May), public conferences, and workshops.
SEDOS began during the Second Vatican Council when nine missionary societies began to meet in an informal way in Rome to exchange information and opinions on mission in the Church. The guiding light was Father Mondé, Superior General of the Society of the Missionaries of Africa, together with other eight Superiors General. The group made a significant contribution to Ad Gentes at the Second Vatican Council, which was greatly influenced by their discussions with members of the Roman Curia.
In 1964 the nine societies wished to have a permanent secretariat. Father Johan Schütte, Superior General of the Society of the Divine Word Missionaries, generously made available the spacious premises on the SVD College grounds, in Rome. Even today, these offices host the SEDOS secretariat and library.
In 1969, SEDOS was already made up of 30 member societies of sisters, brothers, and priests. In December 1995 the number reached 88. At the moment, 2017, we have about 80 members. Many of the members have their Mother House in Rome, others in Ireland, England, France, The Netherlands, Switzerland, Canada, the United States of America, and Mexico. Many of them are major religious missionary societies of the Catholic Church.
