It is Better for Sun and Moon to Drop from Heaven
It's one of Newman's most notorious lines, and a claim I for one wish were untrue: "The Catholic Church holds it better for the sun and moon to drop from heaven, for the earth to fail, and for all the many millions on it to die of starvation in extremest agony, as far as temporal affliction goes, than that one soul, I will not say, should be lost, but should commit one single venial sin, should tell one wilful untruth, or should steal one poor farthing without excuse."
