Atheism has led to some of the “greatest forms of cruelty and violations of justice” known to mankind, the Pope said yesterday.

He also said that humanity would not be saved by scientific progress or political revolution, but only in the hope offered by Christianity.

“A world which has to create its own justice is a world without hope,” he said in an encyclical released yesterday, the most authoritative statement a Pope can issue to the faithful and the second of his pontificate.
