"From the beginning men and women have been filled -- and this is as true today as ever -- with a desire to 'be like God', to attain the heights of God by their own powers," he said, wearing resplendent red and gold vestments.
"Mankind has managed to accomplish so many things: we can fly! We can see, hear and speak to one another from the farthest ends of the earth. And yet the force of gravity which draws us down is powerful," he said.
