lilyflor,
So, then, if I understand you correctly, a science textbook may say the earth is round, but we can believe that it's flat if we want to. It all depends upon our "experiences/worldviews," as you put it. And you ask, "How can one argue another person's experience or views?" Of course, we can think that way if we don't care that he's misled. We can also take that attitude if we believe there is no such thing as absolute truth, and that attitude would of course mean that the Bible is worthless to us.
Sorry, but I can't approach the Bible the way you seem to suggest. Jesus was not a trinitarian, and I can't be either, not if I want to believe what he believed and taught. He was a Jew, and I believe he would say to trinitarians what he told a Samaritan woman: "You don't know what you're worshiping. We Jews know what we're worshiping, because salvation comes from the Jews." (John 4:22) He didn't tell her that her "worldviews" were just as good as anybody else's, including his own.
There is absolutely no evidence that Abraham, Moses, the prophets or Jesus believed in a Trinity. Since the Bible was completed, what they wrote or said has been discarded for something that you describe as "fascinating." But fascination is merely a human emotion, not necessarily God's truth as he sees it.
Isn't your most recent post a contradiction of your first one in this thread? You asked, "Do you think that this would be proof enough for JWs that the WT has changed the bible?" Why would you want to change the so-called "experiences/worldviews" of JWs if in your opinion we should not "argue another person's experience or views"?
As for verses that you claim "can easily be interpreted as supporting the trinity," again I ask, Which ones? Yes, there are verses that can with difficulty be so interpreted, but there are none that can easily be so interpreted. One has to have a fascinatingly great imagination to read into any Bible verse a doctrine that just isn't there, no matter how one twists and turns it. There is some truth in the quote you cited: "To the believer no evidence is necessary." Sadly, lack of evidence is what trinitarians generally accept for the basis of what they believe.
