I'm a little confused by your post. The term Trinity is not in the Bible, but the meaning of the word "Trinity" is all over the Bible. That is why I believe in the Trinity. In other words, God manifested as three persons is all over the Bible as I see it, but I don't think God is going to send someone to hell because they see God manifested in three ways instead of persons. I thought James White may be able to explain it. That's why I left you the link. I don't know if you listened to him or not.
