This is where you will do well by having a King James Bible. Notice the full version of verse 3.
1 John 4:1-3
>Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
>Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God:
>And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
So you see two things here. One, this is saying the spirit of antichrist has just then come into the world, so I don't know if you can apply it to before the resurrection. Two, a false prophet could confess some altered version of Jesus Christ that has not come in the flesh and they wouldn't be passing this. We see that there are a number of ways people can mask this deception, from basic stuff like saying he was not really God or just being a non-trinitarian modalist, to complex things like implying he is a created being and not the literal manifestation of the pre-existent God the Son. You'll find a lot of bibles change 1 Timothy 3:16 (where the KJB says "God was manifest in the flesh") and Ephesians 3:9 to attack this doctrine, the same ones that change 1 John 4:3. Usually they also want to tamper with Hebrews 1:8 to make it less clear. And for some reason, 1 Corinthians 15:47 also gets changed from what it says in the KJV, I'm not entirely sure why. Maybe they will build on the change in later versions.
