Hi there, Kimberblue - and welcome! I'm one of the local heretics. You'll be seeing quite a lot of me around here.
In order to strengthen his case, Jay should have noted that these verses in I John assume that Jesus is God, otherwise they make no sense. Therefore, it is implicit that one must accept Jesus as God as well as accept that He came in the flesh. What john is fighting here is the belief that Jesus came as God only, and that His flesh was an illusion.Let's try this one more time, I stated: I am also worried you did not deal sufficently with my remarks regarding First John. The Apostle John says the following: "This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God, but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the Antichrist, which you have heard is coming and even now is already in the world" (see 1 John 4:1-4).
