The trinity is a confusing subject to many, no doubt about that. If you do a search you will find a ton of questions about the trinity from Christians and non-christians alike.
We have many different explanations for it. Like water ice and steam. The egg-shell, and the football illustrations.
If someone were to ask me if I believe in the trinity, I would say yes. And I have. But then as we started conversing I have been often accused of being a modalist. I had no idea what that is.
Here again is my view of it and how I explain it, so someone can tell me what "ism" im in: I believe in the Godhead. One God. We are made in God's image and we are a body/soul/spirit. How this would work with the Godhead is: Father = Soul, Jesus = body, Holy Spirit = Spirit.
I think its a great and simple way to explain it, if anyone can show me wrong from scripture i'll change my view obviously in a heart beat. I like it because I dont need extra-biblical catholic philosophical ideas and words added to scriptures like "persons" or "essences" or anything like that. Thats just too complicated in my opinion.
Its easy to find verses that prove the deity of Jesus. But its impossible to find a single verse that "proves" the trinity. Which is exactly my problem with it, if its that important God would surely have mentioned it, and there should have been a big controversy among the jews for it. But Paul never writes about it, thats why I believe the "Godhead" would be a proper and biblical word to use instead. This bothers me because when witnessing to people the trinity almost ALWAYS comes up, especially when talking to muslims, OY VEY!
What do YOU personally, believe about the trinity, how would you explain it? If you even believe in it. And if you dont, show scripture why not.
