Interview Episode: The Aggressive Christianity Missions Training Corps with Harrison Hill

ABOUT THIS EPISODE

The Aggressive Christianity Missions Training Corps, or ACMTC, is a hardline fringe religious cult that was led by a former hippie who went by the name Deborah Green. In The Oracle’s Daughter, author Harrison Hill tells the story of the group through the experiences of three women: Deborah, the self-proclaimed oracle; Maura, who nursed Deborah’s ailing brother and became one of her first followers; and Sarah, the oracle’s daughter of the title.

The group’s practices included harsh punishments of children and extreme forms of exorcism, and its crimes included kidnapping and abuse. Through his book, Harrison examines the dwindling gap between the fringe and the mainstream in the United States, and shows how we may be much more vulnerable to extremism than we think.

If you have been personally affected by involvement in a cult, or would like to support those who have been, you can find support with or donate to Cult Information and Family Support if you’re in Australia (via www.cifs.org.au), and you can find resources outside of Australia with the International Cultic Studies Association (via www.icsahome.com).
