IF ANY ONE were a 100% Fully human, that leaves NO room for e.g. a supernatural archangel!

First, perfect has a number of meanings, the most important of them in this context is simply complete. Humans have been incomplete due to imperfection ever since Adam and Eve sinned. Christ, however, was made complete by the operation of holy spirit on the edge in Mary's womb. This was necessary because under the law, only a perfect sacrifice would do. Now to address the actual topic, let me point out that at no time when on this earth was Jesus. Anything other than 100% perfect human. The fact that he had in his head. The full personality and memories of God's son did not alter that fact. Therefore there is no need for any further room inside that 100% perfect human body. To address my opponents other point, may not seem as simple as in fact it is. My opponent states that at no time does Scripture describe the Christ as anything other than a Jew. In that he is perfectly correct. What he fails to take into account, is the fact that whilst Judaism was abandoned, because it's unfaithfulness, faithful individuals would never be abandoned. In fact for some time after Jesus death his followers were known as the sect of Judaism. Paul was very careful in both his letter to the Hebrews, and his letter to the Romans, to explain that this group were actually a new Israel, formed from a rootstock of faithful Jews. Though Judaism was, and still is, left to its own devices by God, the new Israel has never been completely abandoned. Eventually this spiritual Israel became known as Christianity. In the first century, that new, spiritual, Israel, called in Scripture the Israel of God, was faithful to God and Christ but the apostasy put an end to that. Despite that, through the ensuing centuries there was still always one or two faithful servants of God, who, though they knew little of the truth fought hard to save what they found, often dying horribly in the process. When the time was right, Jesus acted as he had in the first century, to pull faithful ones out of the Christianity that was by now thoroughly apostate, and reformed spiritual Israel through those ones, who eventually became known as Jehovah's Witnesses. So, are Jehovah's Witnesses strict adherents of biblical Jews? By no means, however, they are the revived Israel of God that was created to replace Judaism. My opponent would do well to remember that the words Jews and Israelites are not interchangeable. The name due referred to an adherent of Judaism, whereas Israelite refers merely to a member of the nation of Israel. Judaism only emerged when the worship of the sons of Israel became irreversibly apostate. Jehovah's Witnesses adhere very carefully to all the principles to which such ones as Noah, Abraham, and Jesus, as well as the Apostles adhered to. That gives them the right to call themselves not only true Christians, but also spiritual Israelites. Whilst they do not adhere strictly to the law, because it was fulfilled in the Christ, and parts of it will read it impossible to adhere to buy the destruction of the Temple, they do adhere to all the principles behind it. Jesus said to his questioner, when asked what was the most important commandment in the law: You must love Jehovah your God with your whole heart, your whole soul, and your whole mind. He then said: The second like it is this, you must love your neighbour as yourself. On these two commands the whole of the law profits hangs. Therefore, any who obey those two commands have fulfilled the whole of the law. The role of Jehovah's Witnesses, in imitation of their king Jesus Christ, is not only to fulfil those two commands, it is to help others do the same, should they wish to.
