Having spent some time recently visiting a Christian pilgrimage site of some considerable significance to believers (and history buffs as well), it became apparent to me the penitents amongst the crowds stood out. It was pretty clear there is a deep emotional engagement, a heart-felt belief in the Christian dogma, many of the pilgrims feel and adhere to.
It got me thinking about the sort of commitment other spiritual engagements require of their followers if their followers can be expected to remain followers. Other than Reformed Judaism which appears to be based pretty much on cultural tradition most other religious endeavors expect, if not an emotional commitment, an intellectual discipline whereby the metaphysical can be approached, the value of which for the honest participant is cultivation of a groundedness that is helpful in seeing through and beyond the petty and not so petty distractions life presents with considerable constancy.
Problems tend to arise when differences in doctrinal beliefs lead followers to deny the legitimacy of other traditions. It would be good, I think, if more adherents would focus on the common rather than the different and set aside the arrogance of an assumed superiority.
