The antonyms for the phrase 'divine messengers' could range from human messengers, demonic messengers, or even non-existent messengers. Human messengers are persons who carry messages from non-divine sources, such as a king, queen, or messenger from another human being. Demonic messengers, on the other hand, are messengers coming from evil spirits or demonic forces. Lastly, non-existent messengers are completely void of any supernatural or spiritual realm, and therefore do not even exist. In contrast, divine messengers are supposed to be sent by a supreme being, such as angels or prophets, to guide and inspire people towards righteousness and fulfillment.
