David Brandt Berg (February 18, 1919 – October 1, 1994), also known as King David, Mo, Moses David, Father David, Dad, or Grandpa to followers, was the founder and leader of the new religious movement initially called Teens for Christ (1968), then later The Children of God (1969), now called The Family International.
Berg founded this movement in 1968 among the counterculture youth in Southern California.
He came from a long line of non-conformist ministers and evangelists, and he also decided to spend his life dedicated to Christian service.
Initially the group was filled with hippies and unchurched youth, but later drew in followers from many other places.
This is when the Children of God expanded and became known as the Family International.
To communicate with his followers, he began writing letters, and continued this practice for thirty years.
His legacy is highly controversial, however, as he was accused several times of child abuse and sexual misconduct, including by his grandchildren.
He disapproved of mainstream Christians because he thought that they failed to follow the teachings of Christ.
He believed that all Christians should model their lives after the first century church, living a simple life, and devoting their life, time, and money to sharing the Gospel of Christ with as many people as possible.
During the first 25 years of this movement, the Family International claims they shared their message with over 260 million people in over 100 countries.
According to The Family International, 18 million of those people became followers of Christ.
