S. AURELII AUGUSTINI HIPPONENSIS EPISCOPI DE BONO CONJUGALI LIBER UNUS .
17. Posse sane fieri nuptias ex male conjunctis, honesto postea placito consequente, manifestum est.
24. Marriage, I say, is a good, and may be, by sound reason, defended against all calumnies. But with the marriage of the holy fathers, I inquire not what marriage, but what continence, is on a level: or rather not marriage with marriage; for it is an equal gift in all cases given to the mortal nature of men; but men who use marriage, forasmuch as I find not, to compare with other men who used marriage in a far other spirit, we must require what continent persons admit of being compared with those married persons. Unless, haply, Abraham could not contain from marriage, for the sake of the kingdom of heaven, he who, for the sake of the kingdom of heaven, could fearless sacrifice his only pledge of offspring, for whose sake marriage was dear!
24. Bonum, inquam, sunt nuptiae, et contra omnes calumnias possunt sana ratione defendi. Nuptiis tamen sanctorum patrum, non quas nuptias, sed quam 0390 continentiam comparem quaero: imo non nuptias nuptiis; nam par in omnibus munus est mortali hominum naturae datum; sed homines qui nuptiis utuntur, aliis hominibus qui longe aliter nuptiis usi sunt quos conferam quoniam non invenio, quinam continentes illis conjugatis conferendi sint requirendum est. Nisi forte Abraham continere se non posset a nuptiis propter regnum coelorum, qui unicum prolis pignus, propter quod nuptiae charae sunt, potuit intrepidus immolare propter regnum coelorum.
