2:18 Children, it is the last hour, and just as you heard that the antichrist is coming, so now many antichrists 1 have appeared. We know from this that it is the last hour.
1 sn Antichrists are John’s description for the opponents and their false teaching, which is at variance with the apostolic eyewitness testimony about who Jesus is (cf. 1:1-4). The identity of these opponents has been variously debated by scholars, with some contending (1) that these false teachers originally belonged to the group of apostolic leaders, but departed from it (“went out from us,” v. 19). It is much more likely (2) that they arose from within the Christian communities to which John is writing, however, and with which he identifies himself. This identification can be seen in the interchange of the pronouns “we” and “you” between 1:10 and 2:1, for example, where “we” does not refer only to John and the other apostles, but is inclusive, referring to both himself and the Christians he is writing to (2:1, “you”).
