Spirituality is a word thrown around a lot. When I say spirituality, what I mean is Christian spirituality. I believe these quotes from Dissident Discipleship define well Christian spirituality.
…Christian spirituality is truly Christian only when we are seeing through Christ who God is and seeing in Christ who we are.
Spirituality cannot be found at the end of a search for self-fulfillment. Spirituality does not lie at the end of a drive for gratified greed. Spirituality does not associate itself with the life long quest for power and dominance.
