Hi! there mind if I join you?
I personally have not given much importance to the theory of the trinity, because it try to describe God as a form of existence, which i find unhelpful in my quest for holiness. But in Matthew 28: 19, we read, "go therefore and make disciples of all the nations, baptizing them in the name of the father, and the son, and the holy spirit."
and genesis 3: 22, we read, "then the lord god said, "behold, the man has become like one of us, knowing good and evil; and now, lest he stretch out his hand, and take also from the tree of life, and eat, and live forever." so we must conclude that some how he is more than one, forming one god. The trinity is an invented word to explain that mystery; but strangely i see myself as a trinity, because i am in reality three different things such as; my conscience, my soul, and my body, which all together is me, and when you speak to me you affect each one of them in a different manner, like my conscience will judge your moral standing, my soul will decide if i can collaborate with you, my body language will tell me if we can be together in harmony. Also that is the way we make our decisions; have you ever made a decision in which no all of you were in agreement, wasn't that a strange experience.
in conclusion to try to explain God as a trinity is a waste of time for it does not makes us any better or any worse if we believe it or not. Like has it made much difference to you; to know that your conscience is independent from your mind, and that your body is independent from your mind and conscience; they are all individuals necessary to make the one, YOU.
