Christian theology is split on this issue, and different sects are apt to believe different things. . .

First some history: When Christianity was starting out long ago, the gentiles recruited by the evangelists were either former pagans or former Jews. As these early Christians were grappling with the nature of Jesus and the divine, they looked to their old faiths in order to get a handle on who he was.

For example, some early Christians who were formerly of Greek religion looked to Asclepius. Asclepius was a son of Apollo who who went around healing men and performing miracles. He was, however, not allowed to raise men from death, for such a thing was supposed to be beyond the province of men. . .He was exhorted to resurrect a dead fellow, and, for doing this, Asclepius was struck down by Zeus. He was, however, then raised to Mount Olympus and became of the gods. "Oh," some early Christians said. "Asclepius was of man, performed miracles for man, was struck down in his youth, and then adopted into heaven. Jesus is like Asclepius!" And they came to the conclusion that Jesus was some kind of superhuman man who was later raised to heaven by god. (as an interesting side note, many of the early Christian temples were built upon former temples and centers of healing to Asclepius)

Others early Christians looked to other stories: for example, Jews who became Christians saw the story of Elijah the Prophet in the Old Testament, and drew a parallel there: Elijah was a prophet of God who was brought up to heaven because he served God well and true. "Oh," some other people said. "Jesus was like Elijah - he was a human who simply was incredibly pious, served God very well, and was then brought into heaven."

So at any rate, a schism formed from all of these interpretations, and it lasts unto this day. Most Christians believe nowadays that Jesus was actually an incarnation of God, but there is a split over how much like man or how much like God this incarnation was: was he entirely human, and did he doubt, weep, and tremble as men? Was he superhuman, and therefore was at some midpoint? Or we he godly, knew all of what was and what would be, and did not tremble a whit?

The argument for Jesus being extremely human might go like this: mankind has sinned. He has blackened his soul, and he has blackened the Earth. For man to be redeemed, God must come in a profoundly human way and must suffer in a profoundly human way: He must doubt as man, weep as man, and, ultimately, bleed as man. A man who is closer to God than to mankind would be unacceptable - it is men who have sinned and therefore a man must take all of this suffering upon himself.

The argument for Jesus being a "perfect" man is that it was a "perfect" man who got us into this mess, namely Adam. Because a perfect man initiated this cycle of sin, a perfect man is required to end it: Adam ate of the Tree of Life's apple; to atone, Jesus must be mounted upon a tree of thorns.

Yes, I agree. This is all fucked up.

Most conservative portrayals of Jesus have him being "perfect." It's just safer that way. Newer (and inifinitely more interesting) portrayals can be found in several modern works, including the excellent The Last Temptation of Christ and the minorly great Jesus Christ Superstar.
