I imagine that other people have used similar lines in the past, e.g., David Koresh, Joseph Smith.
From the Freethinker:
EVANGELICAL pastor Valdeci Sobrino Picanto hit on a crafty way of getting blowjobs. He convinced his followers that his semen was “holy milk” and, according to one of his flock:
He has convinced us that only God could come into our lives through our mouth and that’s why he would do what he did. Often, after worship, pastor Valdeci would take us to the where the funds were kept at the back of the Church and asked us to have oral sex with him until the Holy Spirit would come through ejaculation.
Picanto said after his arrest that he intended sharing his sacred semen with fellow inmates.
