This paper wants to re-examine the interpretation of Malachi 1:11 that suggests that worship offered in sincerity and truth under the auspices of any religion whatsoever is in effect offered to the one true God. Is this interpretation consistent with Old Testament teaching as a whole on the subject of the worship of the nations? Is it consistent with the prophet's teaching in the rest of Malachi? The author examines these questions, and then takes a fresh look at the text and its interpretation.
