As I understand it, assuming Jesus was at least part God, God is like Mt Everest, incredibly huge, now pick up a small rock or pebble at the base of Mt Everest, is that rock Mt Everest, well yes it actually is a part of Mt Everest, but Mt Everest is much, much, much more than just that small rock or pebble. That small rock or pebble represents Jesus relationship to God, represented by Mt Everest. So In that sense you could say Jesus is God or part of God. But as the muslims so rationally point out, to rank Jesus as equal to God immense power, size, control etc, Is sheer lunacy, so no, Jesus and God are not equal, but perhaps if you have enough faith, Jesus is the closest thing many of us have seen to God living on this earth.
When Pilate questioned Jesus as to whether he was God or the Jewish messiah, his answer was "you say it, not I". I think maybe we should take him at his word, He wasn't going around calling himself the Son of God, he deliberately contradicted his followers by calling himself the Son of Man.
