Bede's Ecclesiastical History of England, ed. by A.M. Sellar, , at sacred-texts.com
IN the meantime, in Britain, there was some respite from foreign, but not from civil war. The cities destroyed by the enemy and abandoned remained in ruins; and the natives, who had escaped the enemy, now fought against each other. Nevertheless, the kings, priests, private men, and the nobility, still remembering the late calamities and slaughters, in some measure kept within bounds; but when these died, and another generation succeeded, which knew nothing of those times, and was only acquainted with the existing peaceable state of things, all the bonds of truth and justice were so entirely broken, that there was not only no trace of them ‘remaining, but only very few persons seemed to retain any memory of them at all. To other crimes beyond description, which their own historian, Gildas, mournfully relates, they added this—that they never preached the faith to the Saxons, or English, who dwelt amongst them. Nevertheless, the goodness of God did not forsake his people, whom he foreknew, but sent to the aforesaid nation much more worthy heralds of the truth, to bring it to the faith.
