The Cambridge Missionary Fellowship (1930) was formed by members of the Cambridge Inter-Collegiate Christian Union (CICCU) who graduated in 1930-31. They resolved to continue to support each other by prayer, circulation of bulletins of correspondence, and financial contributions to the work of members or other Evangelical causes.
