Christianity is an international religion thousands of years old. It's not a personal definition.

And none of it was originally written in English. The English words were chosen because of their definitions, so that it made sense. I’m not sure what you mean by this.

In other news, I come from a family of Christian pastors and I’m quite informed on what words mean in the Bible and which ones actually matter. You are mixing several ones into a single word that has a singular definition that is well defined.
