50 POINTS I need help ;-;

Having begun to speak of the city of God, I have thought it necessary first of all to reply to its enemies, who, eagerly pursuing earthly joys and gaping after transitory things, throw the blame of all the sorrow they suffer in them . . . on the Christian religion, which is the one . . . true religion. And since there is among them also an unlearned rabble [mob], they are stirred up . . . to hate us more bitterly, thinking in their inexperience that things which have happened unwontedly in their days were not wont to happen in other times gone by.
