Response: The usual interpretation has a would-be exorcist demanding of an evil spirit (apparently in possession of a victim) whether Christ has come in the flesh. However, this scripture has nothing to do with exorcism or conversing with evil spirits, but with identifying false prophets and their false teaching. Already in John’s day there were “many false prophets,” and John is declaring that false prophets are inspired by deceiving spirits.

A lying spirit authored both of these deceitful doctrines, which are among the “doctrines of devils” (1 Timothy:4:1Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
