In reply to comment: That is one possible interpretation (see in situ)

heretical interpretations are possible.

Heretical interpretations are possible, but that doesn't mean they are valid. The early disputes about opposing views of God(eg. the Nestorian controversy) focused on accurately handling scripture. The fact that someone can mishandle it doesn't make their view valid. The debate was theological, not political. Theological debate is not a popularity contest, you can look at the arguments which were presented on both sides, and the better arguments are still clearly better, so it is no wonder that most Christians went with the better arguments. There is a lot more support for the Trinity in scripture than what you were replying to.
