Smith started Calvary Chapel in the mid-1960s before ultimately leading the so-called “Jesus Movement” in the 1970s.

His church was filled with hippes and other counter culture youth wearing long hair and sandals. It is now an association of Christian churches with over one thousand congregations around the world.

Smith was recently at the center of controversy in October when he publicly criticized an abuse victim of one of his Calvary Chapel pastors.
