Many have tried to define faith on belief systems, which has done nothing for bringing unity. Others have tried to define unity on practice, or behavior, but this attempt also does not affirm diversity. So, how are we to define and affirm a unity in diversity? Faith.
Faith is in belonging to the human race, which brings unity, while belonging to certain cultures, nationalities, cultures, or traditions, brings about the diverse ways in understanding one's faith. Faith can be in anything, but all of us have faith. Belonging is a matter of finding where we belong, where we agree about how we define our faith. Faith in our common humanity, which needs identification factors in norms of behavior (as defined by religion, culture, or community), will bring about the environment where we can engage in understanding our diverse understandings of faith.
Faith in reason, faith in tradition, or faith in experience will guide the discussion over what our faith means and how that meaning affects our behavior. Behavior cannot be limited to a certain definition, other than a respect and honoring of another's difference. Nor can faith be defined by a spcified understanding, as faith is about our understanding of life itself, which ultimately means we affirm ourselves and another's belonging to the human race.
