"Who is a liar but he that denieth that Jesus is the Christ? He is antichrist that denieth the Father and the Son. Whosoever denieth the Son, the same hath not the Father."
- 1st John, 2:22-23
Forced conclusion: All who deny the Son (referring to the Jews who denied Jesus, and to this day continue to), also deny the Father, and are therefore in league with antichrist.
No more so than anybody not saved.
The statement, like many other similar statements (many by Christ himself), referred to Jews in particular. It was only the Jews whose doctrine told them to look for the coming of "the Christ." The statement only makes sense, therefore, in their context. Furthermore, it was only the Jews who claimed to "have the Father," which was the common way of referring to their one God being Yahweh. Not all non-believers (although unsaved) are in league with antichrist. The New Testament is pretty clear that the Jews are that, in particular, and that for denying (and murdering, see 1 Thessalonians 2:15-16) Christ.
Might I suggest that watering down the Gospel might seem to you like the "nice" thing to do, but it's actually an expression of hate for those who need to receive it in full concentration.
