The Preacher of Righteousness – Malachi 2:1-9

The chief duty of a priest is to show the right way of living to the people; for however upright and holy one may be through his whole life, he is not on that account to be deemed a priest. Hence our Prophet dwells especially on this point — that Levi taught the people. He does not speak of Levi himself; for we know that Levi was dead when Aaron was made a priest. For God does not here speak of individuals, but of the tribe; as though he had said, “Aaron and Eleazar, and those who followed them, knew for what end they were honored with the priesthood, and they faithfully performed their duties.” The Prophet now explains what God mainly requires from priests — to show to the people, as I have already said, the way of living a pious and holy life; but he adopts different words, which yet mean the same thing. – John Calvin
