The following is a serious post from a serious theologian. Me. It is an attempt to best explain the answer and issue with the divinity of Christ in an manner which can be well understood. Like Cali, I do not want to boggle this down into a rehash of the never ending thread, so I am not making any comments about the historicity of Jesus, just the theology of Jesus. So where to begin.
The mythos of Jesus being God was most likely a pinnacle of Hellenism and Israeli mythology fusing into a unique blend of man-god theology. As students of early Christianity know, Christianity did not begin in Jerusalem but rather in small communities within Syria. There, especially near Damascus, the question of Messiah and King was examined. If Jesus was a the Messiah than what authority did that give his teachings? Did his teachings trump the Law? Well if he was just a man alone than no. Moses was a prophet and a redeemer of the Israelites but was still a man and subject to sin. Was Jesus different?
This is when accounts of Jesus' temptations in Matthew and Luke were probably added into the fray. In Mark it said Jesus was tempted and ends the discussion. In Matthew and Luke, both authors explore what Jesus was tempted by to show that he was sinless. In fact, the gospels tend to embellish Jesus' sinlessness in order to drive the point that he was more than a man.
When you get to the Johannian community near the beginning of the second century, this concept is fully integrated with a blend of logos in Greek and word being law and order in Hebrew. Jesus is the law, the word. Therefore Jesus is equal to or above the law and therefore his teachings have equal bearing to the Hebrew law.
If so, then Jesus was more than a man he was truly sent by God. But this begged the question of what was he? Was he a creation of God, like an angel? If so, he was still fallible and the worship of him would be idolatrous. But he was the redeeming servant king from Isaiah 51-53, surely he was worthy of praise? That was what the early communities believed, especially what is now orthodoxy. The gnostics believed Jesus was a spirit of God, not a man. The Marcion's believed Jesus was the Messiah sent by a loving God and the God of Israel was to be rejected as a lesser God of evil and wrath. Regardless of specific doctrine, Jesus was revered by the Christianity community and that reverence started to spread.
We know from the Talmud, that rejection of Jesus' character was the main way the Jewish rabbis handled the new Jewish sect. They accused Jesus of sorcery and deceiving Israel. Now the point of this was most likely a response to the spreading Gospel within Jewish circles and the Rabbis were attempting at halting the worship of Jesus.
But already by the turn of the century, we had people elevating Jesus to a higher standard than just a man. He was getting worshipped, but he could only be worshipped if he was God. So the Christian community did the next best thing, they deified Jesus Christ as the Son of God. Surely if God gave birth to a son, that would mean the son is in the same league as the father. So the virgin birth narratives were exaggerated and drawn out. It was one thing to have Jesus be born of a virgin, it was another thing to have the holy spirit impregnate Mary. This concept drew controversy of course.
It created a polytheistic model. If Jesus was the Son of God, then does that mean he is also a separate God? If he is a separate God, can he be worshipped? How does that fit the model of the 1st Commandment of having no other Gods but YHWH? That is when the Christian community decided to go the final step. Jesus and God are the same. The trinity became a concept by the third century and was a big debate point in the council of Nicea because Arius rejected the trinity as a heresy, which in Jewish mythos, it rightly is.
So there we have a simplified, but hopefully, acceptable summary of the answer of was Jesus human?
The answer is yes, but due to the demands of the shifting culture and Christian community, and in order to justify their behavior such as worshipping the man of Jesus, they created different theological justifications, using the teachings of Jesus as well as Paul's writings and creating their own Gospel accounts to validate their claims.
Hope that helps.
