Applewhite began to emphasize a strict hierarchy, teaching that his students needed his guidance, as he needed the guidance of the Next Level. Zeller notes that this naturally ensured no possibility of the group's continuing if Applewhite were to die. A relationship with Applewhite was said to be the only way to salvation; he encouraged his followers to see him as Christ. Zeller states that the group's previous focus on individual choice was replaced with an emphasis on Applewhite's role as a mediator. Applewhite maintained some aspects of their scientific teachings, but in the 1980s the group became more like a religion in its focus on faith and submission to authority.
