Christian missionaries often witnessed to Indigenous people in an attempt to convert them to Christianity. The Presbyterian Church of Australia’s Australian Inland Mission and the Lutheran mission at Hermannsburg, Northern Territory being examples. Many missionaries often studied Aboriginal society from an Anthropological perspective. Missionaries have made significant contributions to anthropological and linguistic understanding of Indigenous Australians and aspects of Christian services have been adapted when there is Aboriginal involvement – even masses during Papal visits to Australia will include traditional Aboriginal smoking ceremonies. It was the practice of some Missions to enforce a 'forgetting' of Aboriginal culture. Others, like Fr Kevin McKelson of Broome encouraged aboriginal culture and language while also promoting the merits of western style education in the 1960s.
