Actually, there is wrong in believing in Jesus alone. I mean, the Father and the Spirit are part of the Trinity too, aren’t they? If you’re focusing on “Jesus” alone, you’re diminishing God by two-thirds.

But I know that as Christians in saying, “Jesus” you are automatically saying “Father and Spirit” too. And saying “Father” you say “Son and Spirit”. God is a Trinity.
Now, you see how the use of what seems a perfectly innocent phrase in which YOU understood that Jesus = Father = Son all three being God, but Jesus also being Son, Jesus being the Second Person of the Trinity, Jesus being fully man as well as fully God could be miscontrued and misunderstood (and it is by Muslims, anyway) as making Jesus ‘part’ God, or making it appear as though Jesus acted ‘separately’ from the Father or the Spirit.
So I’m sure you don’t separate Jesus from God the Father and the Spirit, Leeann. . . .but it seems while you don’t have trouble with that, you do separate Jesus from His Church and from His people. As the Body of Christ, we are supposed to be One in the Lord ourselves. . .and that means Mary is One in Him, isn’t she? She isn’t God (neither are we) but aren’t we One in Christ? Doesn’t St. John say that?
So Catholics not only don’t separate God into three distinct ‘gods’. . .we also don’t separate Christians from God either.
Now I don’t think you’re a ‘total depravity’ Calvinist, but I do think that perhaps you are more on the "unconscious, invisible’ Church side. . .in which Christians who die either exist on some high inhuman ‘astral plane’ in which they forget about anything ‘human’ and are simply swallowed up in some mysterious ‘other’, or are totally ‘unconcious’, have absolutely no kind of knowledge of themselves or others, especially on earth, and just sort of drift along, neither dead nor alive.
So in order to get some clarity, can you tell me what happens to a Christian who has died. . .and please give the Scripture that supports your view and the requisite apostolic sanction that shows that the apostles taught this from AD 33 on. . .
