Three aspects of Allport's original concept of mature religion appear to be omitted from his later, highly-popular concept of religion as an intrinsic end in itself. These aspects are (a) readiness to face existential questions without reducing their complexity, (b) perception of religious doubts as positive, and (c) openness to future change in one's religious views. Batson and Ventis claim that these three aspects are included in Batson's concept of religion as a quest. Consistent with this claim, evidence is presented which indicates that the quest orientation correlates positively with greater cognitive complexity in dealing with existential concerns, while the intrinsic, end orientation does not.
