I believe there is an important distinction to be made between religion and spirituality. Religion I take to be concerned with belief in the claims to salvation of one faith tradition or another--an aspect of which is acceptance of some form of meta-physical or philosophical reality, including perhaps an idea of heaven or hell. Connected with this are religious teachings or dogma, ritual, prayers and so on. Spirituality I take to be concerned with those qualities of the human spirit--such as love and compassion, patience, tolerance, forgiveness, contentment, a sense of responsibility, a sense of harmony, which bring happiness to both self and others.
