What does Malachi chapter 1 mean?
Malachi is an excellent example of how sophisticated Old Testament poetry can be. Modern chapter and verse divisions don't accurately capture the structure used in this book. Malachi brings three primary messages, addressed to different groups of people. Each message is further divided into two halves, for six total "oracles" within the book. Each message half / oracle is a mirror-image of the concepts mentioned in the first half. As a result, the subject matter of Malachi flows back and forth between ideas, reversing through themes after reaching a main point.The first of the three main messages in Malachi includes all of chapter 1 and the first nine verses of chapter 2. These messages are presented in the form of a dialogue, where God's messenger accuses Israel of various sins. In response to almost all of these, Israel responds with indifference and ignorance: "how have we done that?"
"Malachi" literally means, "My Messenger," so this may or may not be the name of a particular person (Malachi 1:1). Since the priests were supposed to be the messengers of God, attributing these words to God's messenger is a wake-up call to the priesthood. Further supporting this point is that the first portion of Malachi (Malachi 1:1—2:9:) is directed at the priests.
The first accusation given to Israel is simply that God has "loved" them (Malachi 1:2). In other words, God has cared for and protected them. For perspective, Malachi refers to the fate of the nation of Edom. Jacob, the father of the nation of Israel, and Esau, the father of the nation of Edom, were brothers. As prophesied in Obadiah, Edom was destroyed for their many sins (Malachi 1:3–4). Even though Israel has been persecuted and scattered, God has kept them alive and intact. The same was not true of Israel's national "brother." This is given as proof that God has shown more favor to Israel than other people.
The priests are specifically accused of "despising [God's] name." They do this by offering unacceptable sacrifices (Malachi 1:6–7). The priests had been given detailed instructions by Moses on proper sacrifices (Leviticus 22:17–33). Instead, they were offering sick, crippled, or otherwise impure animals. The quality of their offerings was so poor that even a human government official would not have taken them (Malachi 1:8). Likewise, their attitude is bitter and lazy (Malachi 1:13). These are both an insult to God.
God's response to this is a rejection of Israel's worship. In fact, God says He would rather the priests offer no sacrifices at all, rather than improper ones (Malachi 1:10). The sin of bringing God apathetic, selfish, or profane worship is worse than offering no worship at all.
This chapter also includes a combined prophecy and threat to Israel, regarding the Gentiles. Israel knew they were the "chosen nation" of God. The Gentiles, all the non-Jewish people, were not. When God says that He will be worshipped, in purity, by the unclean Gentiles, this is a slap in the face to Israel.
Verses 13 and 14 demonstrate the general apathy of Israel. The priests, in particular, know the right things to do. They are aware of the proper sacrifices, and the right way to teach the people. But they see these as too much trouble (Malachi 1:13). Men routinely make promises to God that they don't keep for selfish reasons (Malachi 1:14).
Even in this condemnation, God's mercy is evident. The penalty for profaning God's holiness, in the Old Testament, is death (Numbers 18:32). Despite their disregard for Him, God is still trying to reach His people, for their own benefit.
