For anyone reading up on the Love Family, this source can be valuable:
Robert W. Balch. 1995. "Charisma and Corruption in the Love Family: Toward a Theory of Corruption Charismatic Cults." Pp. 155-179 in Sex, Lies, and Sanctity: Religion and Deviance in Contemporary North America, edited by Mary Jo Neitz and Marion Goldman. Greenwich, CT: JAI Press.

A quote from a member about the leader Love Israel:
[He would] wake us all up at two or three in the morning, and we'd all come down and he'd have us "duck waddle" around the table and quack. I'm serious ... I remember feeling embarrassed and ridiculous, but that I could overcome my ego. I could do it.
Love Israel/ Paul Erdmann was a charismatic cult leader. He became very self indulgent, his "most significant indulgence was cocaine".
