Faith and Order Commission
Schlink was very involved in the World Council of Churches (WCC). He served as a leading figure on its Faith and Order Commission. He was a delegate to the first assembly of the WCC in Amsterdam (1948), as well as to the assemblies in Evanston (1954), New Delhi (1961), and Uppsala (1968). At the second assembly, he delivered the first keynote address, "Christ--The Hope for the World." Through his ecumenical work with Eastern Orthodox theologians, Schlink helped to bring the Russian Orthodox Church into the WCC in 1961.
