Witness Lee's control early on depended on a church's proximity to Southern California. I was in Texas and early on it was less about WL. Actually Benson Phillips was spoken of more in Texas in those days, because we'd never really seen WL. But once the trainings and videos training started, WL moved front and center. But different regions and cities had different degrees of this. In the Midwest Titus Chu never completely gave up the stage to WL, I don't think.
