17. Posse sane fieri nuptias ex male conjunctis, honesto postea placito consequente, manifestum est.
34. But those of ours who have wives we advise, with all our power, that they dare not to judge of those holy fathers after their own weakness, comparing, as the Apostle says, themselves with themselves;89 2 Cor. x. 12 and therefore, not understanding how great strength the soul hath, doing service unto righteousness against lusts, that it acquiesce not in carnal motions of this sort, or suffer them to glide on or advance unto sexual intercourse beyond the necessity of begetting children, so far as the order of nature, so far as the use of custom, so far as the decrees of laws prescribe. Forsooth it is on this account that men have this suspicion concerning those fathers, in that they themselves have either chosen marriage through incontinence, or use their wives with intemperance. But however let such as are continent, either men, who, on the death of their wives, or, women, who, on the death of their husbands, or both, who, with mutual consent, have vowed continence unto God, know that to them indeed there is due a greater recompense than marriage chastity demands; but, (as regards) the marriages of the holy Fathers, who were joined after the manner of prophecy, who neither in sexual intercourse sought aught save children, nor in children themselves aught save what should set forward Christ coming hereafter in the flesh, not only let them not despise them in comparison of their own purpose, but let them without any doubting prefer them even to their own purpose.
CAPUT XXVI.
34. Continentes hujus temporis non abjecte sentiant de sanctis Patribus conjugatis. Virginitas humilitate tuenda. Nostros autem qui conjuges habent, quantum possumus, admonemus, ne secundum suam infirmitatem de illis sanctis patribus audeant judicare; comparantes, ut ait Apostolus, semetipsos sibimetipsis (II Cor. X, 12); et ideo non intelligentes quantas vires habeat animus justitiae contra libidines serviens, ne carnalibus hujuscemodi motibus acquiescat, eosque in concubitum ultra generandi necessitatem prolabi aut progredi sinat, quantum ordo naturae, quantum morum consuetudo, quantum legum scita praescribunt. Hoc quippe ideo 0396 de illis patribus homines suspicantur, quia ipsi per incontinentiam vel nuptias elegerunt, vel conjugibus intemperanter utuntur. At vero continentes vel mares qui defunctis uxoribus, vel feminae quae defunctis viris, vel utrique qui pari consensu continentiam Deo voverunt, sciant sibi quidem mercedis amplius deberi, quam conjugalis castitas poscit: sed sanctorum patrum nuptias, qui prophetice conjungebantur, qui neque in concubitu nisi prolem, neque in ipsa prole nisi quod in carne venturo Christo proficeret requirebant, non solum prae suo proposito non contemnant, verum etiam suo proposito sine dubitatione praeponant.
