Theodore of Mopsuestia

In his own words on Malachi

• Malachi 3:1

  I for my part shall come, he is saying, whom you look to as punisher of sins. There will be present also the angel who ministers to the agreements I have often made with you. When you seek him, you will find him punishing the transgression of your agreements with me. While the prophet said this as a consequence of what preceded, it is not surprising that the same verse was cited at the coming of blessed John the Baptist, the statement being fulfilled in actual fact by the coming of blessed John as predetermined forerunner and minister, and by the emergence of Christ the Lord, who came at the same time as he and was testified to by him and in whom the salvation of all people was destined to be achieved.

  COMMENTARY ON MALACHI 3:1

• Malachi 4:4

  In addition to all that has been said I transmit this final command to you so that you may keep in mind my law that I gave to the whole of Israel through Moses, having clearly stated that they must observe it in detail. The first token of obedience you will provide, then, will be acceptance of the coming of Christ the Lord, who comes for the salvation of all people. He will bring the law to an end and make clear his own way of perfection. It would therefore be good for you immediately and at the outset to believe in him at his appearance and acknowledge him to be the one that Moses and all the prophets predicted as bringing an end to the law and revealing the salvation of all in common.
