From a historical standpoint, what, in his own lifetime, did Jesus of Nazareth achieve? I am having trouble figuring this out, because I can see objectively that Muhammad had a huge impact upon not only his own society but others, all within his lifetime. That the impact was either good or bad is not my point here, but that had had one. Baha'u'llah had some direct impacts, if small, upon his society. In contrast, I can't think of anything Jesus did that no-one else could have done.
He was born, he preached, he was executed.
This is probably going to turn into an 'It was all Paul not Jesus' thread, but have at it anyway.
Joseph Klausner, a Jewish researcher, sums up some of the conclusions which can be drawn from the Talmudic theories about Jesus: “There are some reliable theories regarding the fact that his name was Yeshua (Yeshu) of Nazareth; that he practised sorcery (that is to say that he performed miracles, as was common in those days) and seduction and led Israel astray; that he mocked the words of the wise and discussed Scripture in the same way as the Pharisees; that he had five disciples; that he said he had not come to revoke the Law, nor to add anything to it; that he was hung upon a piece of wood (crucified) as a false authority and seducer on the eve of the Passover (which fell on a Saturday); and that his disciples cured disease in his name”
