What if the Trinity isn't a thing?

When I asked myself that question, the first thing I thought of was something I remember learning in American History in high school. I remember that during the time of the colonies, several colonists were exiled from their colonies of origin because they denied the existence of the Trinity. They probably went to the colony of Rhode Island to do more heretical things with Anne Hutchinson.

Needless to say, most Protestants consider belief in the Trinity to be a pretty important thing.

But the funny thing is that nowhere in Scripture is the concept of the Trinity mentioned. I easily see how the idea is constructed by logical inference; (1) Jesus claims to be equal with God the Father, and (2) Jesus says he will send his spirit, which is the Holy Spirit. This implies that Jesus is equivalent to God the Father and to the Holy Spirit. We can infer, therefore, that the Holy Spirit is also equivalent to God the Father, although no such direct claim exists that I am aware of. Thus, even though the Trinity is never explicitly mentioned, we can easily see how the idea of it is constructed.

However, the Trinity is a limiting idea. It defines God as three and only three separate but equal beings, or something like that. But what if there are more beings that are part of this unity that are simply not mentioned or alluded to in Scripture? What about the possibility of a Quadinity, Quintinity, or a Hexinity? Or maybe God is comprised of an infinite number of separate but equal beings! We don't know!

It's fun to see how much we actually don't know about God.
