What? I don't quite understand the question but it's one Supreme with 3 faces, 100% for sure.
Edit 1: It's Holy Spirit, not a "Ghost" I find this one rude and probably done on purpose!
Edit 2: Also there are differences between each Orthodox Church so this exact explanation don't have to be true for all of them but most probably is.

There is also the holy pedofile!

Loggically, I don't see how one person can know everything about everyone on this planet at any one second at any one time.

The response would be that they are all parts of one god, so each and all would be all-powerful, all-knowing, etc.

Maybe this 'god' was Confucius in disguise, i.e. Many hands make light work.....LOL.

Yeah, I hear it ALL the from my Jesus Jockey neighbour, i.e. " It is all in Gods great plan."
To me it sounds more like a 'passing the buck' kind of solution in that if something does NOT go well with 'Great Plan' then the blame for the failure gets laid upon ONE of the # rather than all of them.

The construct of The Father, The Son & The Holy Ghost was needed to complete the Christian myth. There are many unexplained inconstancies in the myth regarding how the three can be one entity but that is the story as the word of God is written in the bible by the different authors. Given that the three are one and the one is all powerful then there is no conflict. Does it make sense - not to me but Christian scholars will try and explain it by saying "it is in the bible -believe it".

I think maybe the Son and the Holy Ghost are tools of human thought by which we interface with Ultimate Reality, otherwise totally inaccessible using the space/time/matter model of our perception.

It would probably be better to give them less magical-sounding labels. Subjective higher self and subconscious mind perhaps.

"It's a sacred mystery"

The response to me has been, "Stop being so intellectual, and just accept it on faith. We don't have to understand everything."

When they say that to me, I insist that unless they can show me reasonable evidence I cannot believe.

The trinity is loosen explained as the 3 ways the god interact with the world.
Imagine that you are the player in the SIM game.
You can control the time speed, the sims itself, or their houses, for the sim they see the commander, the builder and the time wizzard, but in the end it is just the way their limited perception sees your interacrions over the world.

I think the trinity is explained as the Father, Son, and Holy Ghost are aspect of the one God. The roles of the 3 individuals are preserves (supposedly) without violating the monotheistic claim of the religion. I don't believe it makes sense but this is why I'm here and not at church today.

I am also interested in the contradiction of the claim of omnibenevolence and omnipotence with the existence of evil in this world. If God is the creator of all, wouldn't this include evil? If not creating evil directly, God would have to at least allow its creation. My thoughts originate from a quote attributed to Epicurus.

"Is God willing to prevent evil, but not able? Then he is not omnipotent. 
Is he able, but not willing? Then he is malevolent. 
Is he both able and willing? Then whence cometh evil? 
Is he neither able nor willing? Then why call him God?”

First remember that you are dealing with undeveloped minds who still have that mind-set. Just a part of the typical indoctrination (Muslims do the same thing, but that's a discussion for another time). My father is a minister and I remember believing in that way. I just always thought of it as the god figure being number one, and the god could pass his powers to his son, and he could also just send his spirit out into the universe kind of like a drone with a camera sending a picture back to your phone. But the god figure would always be in control. (how did I ever believe that shit?)

Don't care because it is all BS. Don't want to spend a second more to understand this shit.

God works in mysterious ways. It is not a quandary for believers. It is an accepted fact and no further explanations needed. _____* says it, I believe it, that settles it.
