MD, I believe that every human being is called to have a relationship with God and that the path of least resistance to that relationship depends upon a combination of nature and nurture factors that shape individual personalities and comfort zones.   Those that were raised in a strict rules-based environment may feel most comfortable in their search for a relationship with God if their search is structured by the doctrines of an organized religion.  Others that were raised in a culture and environment where they were encouraged to be critical thinkers at an early age may feel that the same rules proscribed by Church doctrine are a hindrance to growing their relationship with God.

Rather than condemn those whose comfort zone in their search for a relationship with God differs from our own, we should encourage them to follow their path in their way as God directs them.
