Sicut amici adulantes pervertunt, sic inimici litigantes plerumque corrigunt.
Augustine Confessions Chapter 9
Just as flattering friends destroy, so quarrelsome enemies often correct.
This is the kind of thing Augustine loves. The antithesis. Rhetorically speaking: two contrasting statements written in grammatically parallel ways.
- amici = inimici friends = enemies (plural subjects)
- adulantes = litigantes flattering = quarreling (present active participles)
- pervertunt = corrigunt destroy = correct (plural verbs)
