The book of Malachi offers no clear pointer to the date of its composition. Nevertheless, most scholars agree that Malachi was probably a contemporary of Ezra and Nehemiah in the mid-fifth century B.C. This is supported by the implied existence of the temple (Mal. 1:10; 3:1, 8), which requires a date after its reconstruction c. 516 B.C.
The mention of the temple highlights Malachi’s focus on worship. Malachi’s contemporaries may have been free from blatant idolatry (though see Mal. 2:11) and relatively orthodox in their beliefs, but theirs had become a dead orthodoxy. They were all too ready to make ethical compromises and to dilute the strenuous demands of proper worship. In response to the cynicism and religious malaise of his contemporaries, Malachi’s prophecy comes as a wake-up call to renewed covenant fidelity.
