Just to add a bit; isn't it also believed by xtians that when they die and go to heaven they will actually see jc? So if they are going to see jc, where are the other 2 "parts". Will they also see G-d himself and the holy spirit?

How will they see the ONE G-d of creation if they say they will actually see jc?
That sounds like 2 to me, just like Chaim said "Doesn't the NT teach that the son actually sits next to the father, at His right hand? Doesn't the NT claim that this was literally seen by some observers? ".
