"We nurture our children selflessly. But we also recognize them as our most tangible sources of renewal — for a child, the world is always new. Renewal has been a religious theme throughout the ages … All of us see in children — our own and all children — the hope and promise of what we humans can become. As the forbears of our children we are called to transmit to them a joyous and sustainable vision of their future — meaning that we are each called to develop such a vision."
