Um, it absolutely matters if you are going to believe in that religion. If the "trinity" and the things within it are one, you are not just trying to live your life like jesus intended, you are living it like god intended, and the holy spirit (whatever that is) intended. So you go into the bible and look at all of those things. If it's one, it has to be the other, according to the logic of the "trinity". Of course, when you do this, you see absolutely horrific things that god (jesus and holy spirit) did. I'd say that more people live by the "teachings of jesus" and do not believe in christianity than actual christians. If you actually read and see what it tells you to do, most people do not do this out of convenience, wanting to have nice material things, wanting to have their own kids, wanting a retirement, and so on.Im not even going to attempt to explain (or understand) the whole Trinity, I personally dont give it much thought in my understanding of my faith. I do so for two primary reasons:
A) Ask any Jew to explain how God is omnipotent and yet humans have free will and theyll tell you its a mystery. That mode of thinking, that Hebrew/Eastern way of thinking is very comfortable holding two seemingly contradictory ideas to be simultaneously true. Our Greek/Western educated minds hate trying to resolve that. Im comfortable with embracing the mystery.
B) Second, WTF does it matter? My job is to live out as best I can the teachings of Jesus and as a byproduct bring heaven to earth in every way I can. What does it really matter if I have the Trinity idea understood or lined up correctly in my mind?
.
I understand the trinity just fine, it just makes no sense.
The point is it makes no sense, man continually tries to do this and formulate interpretations that "make sense", hence tens of thousands of religions in this world. This is people making up stories to explain things that contradict, are against what they'd like, and that simply make no sense. This is the premise of religion, making up stories for things that are not understood and to deal with the fear of dying.
