Who served as the last Old Testament prophet?

• A. Malachi
• B. Zechariah
• C. Haggai
• D. Obadiah

Answer: (A)

The question tests knowing who stands as the final prophetic voice in the Old Testament canon. Malachi is considered the last Old Testament prophet because his book closes the collection of prophetic writings and marks the end of that era before the long period of silence between the Old and New Testaments. Zechariah and Haggai were active earlier, during the post-exilic rebuilding period, while Obadiah is an even earlier voice in the prophet sequence. Malachi’s message fits the late post-exilic context, addressing Judah just after the temple era and foreshadowing the coming messenger, a figure many Christians connect with John the Baptist. So Malachi is the final prophet in the Old Testament order.
