Peace ali,
Here is what I believe as a Christian.
I believe in God the Father Almighty, Creator of all things.
I believe in Jesus Christ, the One and Only Savior.
I believe in the Holy Spirit, for guidance and protection.
Each of the trinity having a seperate purpose. God created us and shows mercy on us, Jesus carried the sins of the world upon him and saved us, the Holy Spirit guides and protects us.
But in the New Covenant, the only thing I need to for salvation is in Jesus's words, "the Kingdon of God can be sought and entered through me."
Ali, this is just my belief of the truth, and Im sure doesnt answer your question. But what I always feel regarding the question of the trinity is: we are 1 dimensional humans trying to explain and understand a un-demensional God. He never asked us to understand him, he only asks for our faith
Peace and Godspeed to you.
