The Book of the Prophet Malachi
The Book of Malachi is the final book of the Old Testament and serves as a bridge to the message of the Gospels by promising the coming of a new messenger. It addresses a community that has become indifferent to the things of God and has grown lax in their worship and their moral lives. The prophet calls for a return to the purity of the Covenant and the proper offering of sacrifices from a heart that truly honors the Lord. This book reminds us that our faith should never become a matter of mere routine or convenience.
The text includes a magnificent promise of a future and perfect sacrifice that will be offered among all nations from the rising to the setting of the sun. Catholic theology sees in this prophecy a clear reference to the Holy Sacrifice of the Mass that is celebrated throughout the world. We are also told to expect the return of Elijah who will prepare the way for the Day of the Lord by turning the hearts of parents to their children. The Book of Malachi leaves us with a sense of expectation and a call to readiness for the arrival of the Savior.
