Although he asks "What is Jesus," I prefer the question "Who is Jesus" because he is a person. Indeed, Jesus asked his follower's who do you say that I am. Peter answered "you are the Christ, the son of the living God." These are very powerful words in such a short sentence.
In person, Jesus had to be fully man. This added meaning to his suffering. If he was not fully man, the suffering would not have had an affect on him. He also had to be fully God. This was necessary to allow his sacrifice to cover all sins, past, present and future.
Before concluding, I cannot ignore one of the comments that I saw on Ely's page. It reads as follows
It's an interesting way of editing Jesus into something that fits with what Christianity requires. As you say, assuming of course he existed at all..
The real question is what will you do with Jesus considering all he did for you.
