God (to the third power)

I have some questions about the Christian view of the trinity. I’ll start with what we know:

1. The bible hints at three different forms God can take.
2. The concept “trinity” is never mentioned.

What I don’t understand is why Christians have decided that the three forms we have been told about is all there is. They decided that God is a trinity and made it a central part of every statement of faith I’ve ever seen.

What if there are 16 forms God can take but we simply can’t percieve them yet… Or 16,000…

Making something up about God… TRYING to piece God together… Then claiming the results as the one true definition of God seems like an arrogant thing to do. And limiting God to our human logic makes God small enough and comfortable enough to fit on the shelf…

And maybe this is why taking the mystery out of God leaves us with a boring made up human faith… Rather than an infinate mysterious inpercievable puzzle… Of which we have only been given a small piece of the solution.
