The Wisconsin Evangelical Lutheran Synod (WELS) began mission work in Hong Kong and Taiwan in the 1960s. This work led to the formation of a sister church body South Asia Lutheran Evangelical Mission (SALEM). WELS and SALEM worked together to establish a Bible Institute in order to train current and future Hong Kong Christian leaders. Students advanced beyond the Bible Institute level so ALS was established on May 29, 2005.
Since 2005, ALS has grown beyond the Hong Kong contingent and now offers an online Mandarin program for mandarin speakers who wish to pursue a theological education. ALS has also now offers theological training in English to serve the needs of the church across many countries and cultures in Asia.
