Imaginary. A charismatic nut job man who called himself Jesus may have existed, but it's pretty obvious that he wasn't the God he claimed to be. Logic says otherwise. Not to mention reality.
The true identity of jesus Christ is true God and true Man. The second person of the Holy Trinity and the begotten Son of God the Father, Therefore, Since we are all children of God, Jesus Christ is our Brother and Savior.
Can Jesus be only one thing? Are you only one thing? Are you not a child (of parents), a young adult, a student, maybe a mentor or coach? Jesus is the way, the truth, and the life. He is the bread of life, the living water, the door of the sheep, the one who stands at the door and knocks, the lamb of God... he is all of these things, and more.
