According to their detractors, they are heretics, cultists and polygamists, spawned by a twisted prophet preaching a strange brew of Christian compassion and free love. But to Sarah Lieberman, the oldest of 10 children born to a female member of the sect, the Children of God have been misunderstood and maligned.
"People think this is all about sex," said Lieberman, 25. "But it's greater than sexual relations. It's about how you relate and feel about people. It's about loving God with all your soul."
Founded in the late 1960s by David "Moses" Berg, this underground church was one of the most notorious sects of the 1970s and '80s.
Christian history is replete with movements inspired by self-proclaimed prophets--messianic leaders who claim they are the mouthpiece for God. Few of those prophets, however, were as obsessed with sex as David Berg.
"We have a sexy God and a sexy religion with a very sexy leader with an extremely sexy young following," Berg wrote. "So if you don't like sex, you better get out while you can."
Berg also made it clear that his word was God's word. "I am God's man for this hour, and I am the prophet of God for you," he said. "You had better believe it or you are in serious spiritual trouble."
Berg died in 1994, but his movement lives on today as "The Family."
Other survivors of the Children of God include hundreds--perhaps thousands--of "Jesus babies" born in the 1970s and '80s. Their mothers were young missionaries who followed Berg's call to share sexual favors in order to bring young men to Christ.
"We came from a generation that wanted something different," said Marina Tafuri, who was 16 when she joined Berg's sect in 1977.
Berg was born in Oakland in 1919, the son of famous evangelist Virginia Brandt Berg. He was nearly 50 years old when he began preaching in a Huntington Beach coffeehouse run by "Teen Challenge," a Christian outreach group affiliated with the Assemblies of God denomination.
Berg's early flock, a growing band of hippies, political radicals, and "Jesus freaks," left Huntington Beach in 1969. In the early '70s, they formed Christian communes in California and Texas--the first of dozens of small "intentional communities" that would spring up around the world.
Within a few years, "Moses" Berg disappeared from public sight. But he continued promoting his prophecies in a series of missives, called "Mo letters," dispatched to his far-flung flock.
One of the most detailed examinations of Berg's prophecies and sexual practices is contained in a voluminous 1995 court judgment in a British child custody case. In his conclusion, Lord Justice Alan Ward wrote that, at least until 1986, there was widespread child-to-child sex and sexual abuse of minors by adult members of the Children of God.
Citing the prophet's explicit writings depicting young children as "sexual beings," the judge ruled that Berg "bears responsibility for propagating the doctrine which so grievously misled his flock and injured the children within it."
Another independent observer who has studied the Children of God, Steve Kent, agreed with Ward's conclusion that The Family has now stopped most of its past excesses. But both men say the current leaders, including the founder's widow, the "prophetess" Maria Berg, must address the continuing psychological damage upon the descendants of the Children of God.
"What about the long-term effect on the children from that period?" said Kent, a professor of sociology at the University of Alberta. "Some have been able to pull themselves up, but many of them wound up in the sex trade."
Williams, author of the book "Heaven's Harlots: My Fifteen Years in a Sex Cult," soon found herself sharing more than her material possessions. One of Berg's teachings was called "the law of love," which included the "sexual sharing" of husbands and wives.
"God will have no other gods before Him, not even the marriage god," Berg proclaimed. "Partiality toward your own wife or husband...strikes against the unity and supremacy of God's Family and its oneness and wholeness."
In the search for new converts, Williams and her female brethren soon were encouraged to expand the "law of love" beyond the confines of their sect. They called it "flirty fishing," after Jesus of Nazareth's call that they become "fishers of men."
