I would define spirituality as the experience and expression of compassion for the other. And I would define religion as the ideation and institutionalization of spirituality that both affirms and negates compassion for the other. So the challenge for people of goodwill of all religions is to discover what affirms true spirituality in their religion and what negates true spirituality in their religion.
And as a Christian the challenge for me is to find what affirms true spirituality within my tradition and challenge that which negates true spirituality. And for me that's focused on the person of Jesus and his example. And that for me is an inspiring kind of enchanting model of the way that I would love to live my life.
