Can't help but relate the doctrinal style (my opposite style) with the typology of thinking/feeling aspects of one's personality. As I understand this part of one's personality, it represents the ways in which a person typically makes a decision - either on facts/logic or on feelings. It appears that "thinking, embracing systems, content over experience, objectivity" take precedence in one's connection with God, and may have a correlation with that part of one's personality.
I feel I need help understanding the clarity C. Schwarz makes in focusing on one's connection to GOD - and not simply our personality, reflected in the day to day.
