David Berg, a former Christian and Missionary Alliance pastor, gathered young hippie converts in Huntington Beach in 1968 and led them as 'Moses David'. Members gave up their possessions and lived in communal 'homes' around the world, guided by his 'Mo Letters'. From 1974 to 1987 Berg directed women to use sex to win converts and donors ('Flirty Fishing'), and his writings promoted sexual contact involving children. He lived in hiding from the mid-1970s and died in 1994, after which his partner Karen Zerby led the group.
In academic terms, berg combined high epistemic and devotion closure (forsake-all communism, sexual 'sharing' as obedience) with high temporal urgency, while governing from hiding. The harm was directed inward at members and especially children, not outward.
Where scholars disagree
The case that the framework fits
Ex-member testimony, Berg's own published letters and British court findings in 1995 show sexual exploitation of women and children and tight control through prophecy. Chancellor's interviewees also confirm abuse in the 1970s and 1980s.
The case that it does not fit, or overstates
Lewis and Melton argued that 1990s raids that removed children found no current abuse and that critics reported an older era. Chancellor holds that many members experienced genuine faith and that the group reformed its sexual practices after 1986.
The five walls
5.8 of 10
- 7
1.
Who decides what is real?
Mo Letters were treated as God's word for the age, and outside media and churches were dismissed as 'the System'. Criticism of Berg led to discipline or expulsion.
- 7
2.
Are friends and family outside the group cut off?
Converts were told to forsake parents, who were often treated as Systemites, and children were raised communally and moved between homes. Berg's own writings encouraged sexual activity by and with children, which former members later documented as abuse.
- 5
3.
How hard is it to physically leave?
Members lived in communal homes, moved often between countries and depended on the group for money and housing. There were no armed guards, and many members left.
- 7
4.
Is an apocalypse or a destined triumph always near?
Berg predicted catastrophe from Comet Kohoutek in 1973, a Great Tribulation beginning about 1989 and Christ's return in 1993. Members were urged to flee America and live as end-time missionaries.
- 3
5.
Does the group decide who deserves to live?
Outsiders were 'Systemites' outside God's will, and Berg wrote harshly about Jews and the churches. There is no doctrine of violence against critics.
Debt, dependence and harm
8 of 10, high
How much do followers feel they owe?
Members surrendered all possessions on joining, worked for the group and were required to obey sexual directives such as Flirty Fishing and sexual sharing. Confession and public correction were common.
6 of 10, medium
How far does everything rest on one person?
A 'Chain' of leaders existed until Berg dissolved it in the 1978 Reorganisation Nationalisation Revolution. Zerby succeeded him smoothly in 1994, so some succession planning existed.
-5, mostly insiders
When the system turns violent, where does the harm go?
Serious abuse fell on members, especially the sexual abuse of children documented by former members and a 1995 British court judgment, without lethal violence during Berg's lifetime. Nothing comparable was directed at outsiders.
Methods of control
Specific techniques from the historical record that kept followers loyal and the bubble sealed.
- 01Forsake-all surrender of property
- 02Mo Letters as continuing revelation
- 03Flirty Fishing and sexual sharing as obedience
- 04Frequent relocation between countries
- 05Communal childrearing with sexualised teaching
- 06Leader in hiding issuing directives
Against the reference cases
State power, violence aimed outward
Compared with Hitler
Unlike Hitler, Berg had no external target or state, and his apocalyptic expectations drove members abroad rather than toward conquest.
A sealed group, violence aimed inward
Compared with Jones
Like Jones, Berg used sexual access and total surrender as signs of loyalty, but his movement was scattered across small homes rather than sealed in one enclave.
Through the theorists
Berg's authority was pure prophetic charisma delivered in writing, which let him rule from hiding.
Wallis
The movement moved from a world-rejecting Jesus sect to an antinomian prophetic one in which the leader's revelations overrode biblical norms.
Chancellor
Members' own accounts show how ordinary believers made meaning within a deeply flawed and abusive system.
Key sources
Moderate evidence base

Caveats
Scores describe 1974 to 1987, when sexual directives were strongest. Sympathetic and hostile scholars disagree sharply, and some evidence of child abuse comes from litigation. The group revised its policies after 1986, and the 2005 murder-suicide by Ricky Rodriguez falls after Berg's death.
