Consider very carefully what Pilgrim said in reply to you.
The word "Trinity" may be a made up word that is not found in the Bible. However, the doctrine (teaching) of the Trinity is found throughout Scripture, it is NOT a man made doctrine.

If you disagree with that, please say so and show proof from the Bible itself.
The doctrine of the Trinity is absolutely essential to the Christian faith.

By the way, if you are frustrated with our replies to you. It is probably because up until this point you have been quite vague and we have had to guess as to what your point is.
I am not even sure if your problem is with the actual doctrine of the Trinity itself, or the word Trinity itself.
If the later, I must say that I know of no true Church denomination that would agree with you.
