I have excerpted and paraphrased this message by Pope Benedict XVI:

Unity that is not dependent on uniformity to form a culture not defined by boundaries...but, fundamentally, shaped by the principles and actions that stem from belief, can "teach the deeper spiritual values of our common humanity. The hearts of the young, readily, join those of all religions wishing to safeguard children from fanaticism and violence while preparing them to be builders of a better world."
