Genesis 25:33

15. And therefore also did I read there, that they had changed the glory of Thy incorruptible nature into idols and divers forms, “into an image made like to corruptible man, and to birds, and four-footed beasts, and creeping things,” namely, into that Egyptian food for which Esau lost his birthright; for that Thy first-born people worshipped the head of a four-footed beast instead of Thee, turning back in heart towards Egypt, and prostrating Thy image, their own soul, before the image “of an ox that eateth grass.” These things found I there; but I fed not on them. For it pleased Thee, O Lord, to take away the reproach of diminution from Jacob, that the elder should serve the younger; and Thou hast called the Gentiles into Thine inheritance. …

21. Therefore the heretic is not "the first to seize baptism," since he has received it from the Church. Nor, though he seceded, could baptism have been lost by him whom we assert no longer to retain the Church, and yet allow to retain baptism. Nor does any one "yield his birthright, and give it to a heretic," because he says that he took away with him what he could not give lawfully, but what would yet be according to law when given; or that he no longer has lawfully what yet is in accordance with law in his possession. …

5. “He hath chosen an inheritance for us, the excellency of Jacob, whom He loved” ( ver. 4 ). A certain beauty of Jacob He hath chosen for our inheritance. Esau and Jacob were two brothers; in their mother’s womb both struggled, and by this struggle their mother’s bowels were shaken; and while they two were yet therein, the younger was elected and preferred to the elder, and it was said, “Two peoples are in thy womb, and the elder shall serve the younger.” Among all nations is the elder, among all nations the younger; but the younger is in good Christians, elect, godly, faithful; the elder in the proud, unworthy, sinful, stubborn, defending rather than confessing their sins: as was also the very people of the Jews, “being ignorant of God’s righteousness, and going about to establish their own righteousness.” But for that it is said, “The elder shall serve the younger;” it is manifest tha …

3. Let us therefore consider what we are taught here; since both those deeds were typical of us, and these words exhort us to recognise ourselves. For if we hold with a firm heart the grace of God which hath been given us, we are Israel, the seed of Abraham: unto us the Apostle saith, “Therefore are ye the seed of Abraham.”…Let therefore no Christian consider himself alien to the name of Israel. For we are joined in the corner stone with those among the Jews who believed, among whom we find the Apostles chief. Hence our Lord in another passage saith, “And other sheep I have, which are not of this fold; them also I must bring, that there may be one fold and one Shepherd.” The Christian people then is rather Israel, and the same is preferably the house of Jacob; for Israel and Jacob are the same. …

Let us consider our very make, and we shall see there is in us but one little part that has this operation, for our mouth and tongue are meant for singing hymns, our throat for voice, therefore the very necessity of nature has tied us down, that we may not, even involuntarily, get into much trouble ( πραγματείαν ) (in this way). Since, if indeed luxurious living had not its pains, nor sickness and infirmities, it might be tolerated: but as the case is, He hath stinted thee by restrictions of nature, that even if thou wish to exceed, thou mayest not be able to do so. Is not pleasure thine object, beloved? This thou shalt find from moderation. Is not health? This too thou shalt so gain. Is not easiness of mind? This too. …
