Malachi 1:2-5

Hence he says, I loved you. God might indeed have made an appeal to the Jews on another ground; for had he not manifested his love to them, they were yet bound to submit to his authority. He does not indeed speak here of God’s love generally, such as he shows to the whole human race; but he condemns the Jews, inasmuch as having been freely adopted by God as his holy and peculiar people, they yet forgot this honor, and despised the Giver, and regarded what he taught them as nothing. When therefore God says that he loved the Jews, we see that his object was to convict them of ingratitude for having despised the singular favor bestowed on them alone, rather than to press that authority which he possesses over all mankind in common. God then might have thus addressed them, “I have created you, and have been to you a kind Father; by my favor does the sun shine on you daily, and the earth produces its fruit; in a word, I hold you bound to me by innumerable benefits.” God might have thus spoken to them; but as I have said, his object was to bring forward the gratuitous adoption with which he had favored the seed of Abraham; for it was a less endurable impiety, that they had despised so incomparable a favor; inasmuch as God had preferred them to all other nations, not on the ground of merit or of any worthiness, but because it had so pleased him. This then is the reason why the Prophet begins by saying, that the Jews had been loved by God: for they had made the worst return for this gratuitous favor, when they despised his doctrine. This is the first thing.

There is further no doubt but that he indirectly condemns their ingratitude when he says, In what hast thou loved us? The words indeed may be thus explained — “If ye say, or if ye ask, In what have I loved you? Even in this — I preferred your father Jacob to Esau, when yet they were twin brothers.” But we shall see in other places that the Jews by evasions malignantly obscured God’s favor, and that this wickedness is in similar words condemned. Hence the Prophet, seeing that he had to do with debased men, who would not easily yield to God nor acknowledge his kindness by a free and ingenuous confession, introduces them here as speaking thus clamorously, “He! when hast thou loved us! in what! the tokens of thy love do not appear.” He answers in God’s name, Esau was Jacob’s brother; and yet I loved Jacob, and Esau I hated.”
