STM started as a joint-venture among the Anglican Diocese of West Malaysia, the Methodists and the Evangelical Lutheran Church of Malaysia and Singapore (ELCMS) in Malaysia and was opened on 6 January 1979 (Feast of Epiphany). Its stated aim in the Companies Act of Malaysia under which it was incorporated was "to provide education in the Christian faith for the service in the ministry, worship and witness of the Church." This venture built upon a 1974 collaboration between the Anglicans and the Evangelical Lutherans that saw the merger of the Christian Training Centre (founded by the Lutherans in 1969) and the St. Mark's Training Centre (founded by the Anglicans in 1970) that was called "Kolej Theologi Malaysia" (KTM) or Malaysia Theological College (in English).
