Isaias 56:4

Et rursus cure dicit: “Bonum est homini uxorem non tangere, sed propter fornicationes unusquisque suam uxorem habeat;” id veluti exponens, rursus dicit: “Ne vos tentet Satanas.” Non enim iis, qui continenter utuntur matrimonio propter solam liberorum procreationem, dicit, “propter intemperantiam;” sed iis, qui finem liberorum procreationis cupiunt transilire: ne, cure nimium annuerit noster adversarius, excitet appetitionem ad alienas voluptates. Fortasse autem quoniam iis, qui juste vivunt, resistit propter æmulationem, et adversus eos contendit, volens eos ad suos ordines traducere, per laboriosam continentiam eis vult præbere occasionera. Merito ergo dicit: “Melius est matrimonio jungi quam uri,” ut “vir reddat debiturn uxori, et uxor viro, et ne frustrentur invicem” hoc divino ad generationera dato auxilio. …

3. Do you wish then to know in what manner the Word of God, who was again the Son of God, as He was of old the Word, communicated His revelations to the blessed prophets in former times? Well, as the Word shows His compassion and His denial of all respect of persons by all the saints, He enlightens them and adapts them to that which is advantageous for us, like a skilful physician, understanding the weakness of men. And the ignorant He loves to teach, and the erring He turns again to His own true way. And by those who live by faith He is easily found; and to those of pure eye and holy heart, who desire to knock at the door, He opens immediately. For He casts away none of His servants as unworthy of the divine mysteries. He does not esteem the rich man more highly than the poor, nor does He despise the poor man for his poverty. …

13. If Faustus thinks Moses an enemy of continence or virginity because he says, "Cursed is everyone that raiseth not up seed in Israel," let them hear the words of Isaiah: "Thus saith the Lord to all eunuchs; To them who keep my precepts, and choose the things that please me, and regard my covenant, will I give in my house and within my walls a place and a name better than of sons and of daughters; I will give them an everlasting name, that shall not be cut off." Though our adversaries disagree with Moses, if they agree with Isaiah it is something gained. …

55. (3.) Such has been the state of mind under which Christ’s enemies have fallen into their execrable heresy. For had they known the person, and the subject, and the season of the Apostle’s words, they would not have expounded of Christ’s divinity what belongs to His manhood, nor in their folly have committed so great an act of irreligion. Now this will be readily seen, if one expounds properly the beginning of this lection. For the Apostle says, ‘God who at sundry times and divers manners spake in times past unto the fathers by the prophets, hath in these last days spoken unto us by His Son;’ then again shortly after he says, ‘when He had by Himself purged our sins, He sat down on the right hand of the Majesty on high, having become so much better than the Angels, as He hath by inheritance obtained a more excellent Name than they.’ It appears then that the Apostle’s words make mention …

But, on the other hand, those that are unacquainted with the sins of the flesh are to be admonished to fear headlong ruin the more anxiously, as they stand upon a higher eminence. They are to be admonished to be aware that the more prominent be the place they stand on, so much the more frequent are the arrows of the lier-in-wait by which they are assailed. For he is wont to rouse himself the more ardently, the more stoutly he sees himself to be vanquished: and so much the more he scorns and feels it intolerable to be vanquished, as he perceives the unbroken camp of weak flesh to be set in array against him. They are to be admonished to look up incessantly to the rewards, and then undoubtedly they will gladly tread under foot the labours of temptation which they endure. …
