Anonymous - O bone Jesu - текст песни (слова), перевод

(The text appears as one long sentence in the source, without punctuation or capital letters except for 'Iesu', so the text division is editorial; the third and fourth sentences are apparently quoted from a prayer for mercy written by St Augustine.) 
 O bone Iesu, salvator mundi, miserere nobis.
 Cognoscimus quia peccavimus; veniam petimus quam non meremur.
 Vita nostra in dolore suspirat et in opere se non emendat.
 Si expectas non corrigimur; si vindicas non duramus.
 Ergo bone Iesu, salvator mundi, miserere nobis.
