“For the spiritual power of a sacrament is like light in this way: it is both received pure by those to be enlightened, and if it passes through the impure it is not defiled.”
Spiritalis enim virtus Sacramenti ita est ut lux: et ab illuminandis pura excipitur, et si per immundos transeat, non inquinatur.

The sun, too, shines into cesspools and is not polluted.
Diogenes Laërtius, Lib. vi. section 63

“It is reported that there was then such perfect peace in Britain, wheresoever the dominion of King Edwin extended, that, as is still proverbially said, a woman with her newborn babe might walk throughout the island, from sea to sea, without receiving any harm.”
Tanta eo tempore pax in Britannia fuisse perhibetur, ut, sicut usque hodie in proverbio dicitur, etiamsi mulier una cum recens nato parvulo vellet totam perambulare insulam a mari ad mare, nullo se laedente valeret.
