Ancient Greeks believed other culture's gods are the same deities as theirs, just having different names. For example, Plutarch said
Not different gods for different peoples, not non-Greek and Greek, not southern and northern gods; but just as sun and moon and earth and sea are common to all men, though they are called by different names by different peoples, so of the Reason (Logos) that orders all things, and of one Providence that also directs powers ordained to serve under her for all purposes, have different honours and titles been made according to their laws by different nations.
How can this be interpreted from a biblical perspective?
