Where did you learn what you know about Jesus?
Everyone in America hears about Jesus from various media, Christian culture, etc. I also believe that I learned more about him and his legacy by studying the Bible (and its context), classical civilizations in general, and other parallel traditions.
Who do you think Jesus was?
He was a Jewish prophetic figure who gained a following in Judea sometime around the early 1st century CE. He was one of various people who were seen by their followers as the fulfillment of Messianic prophecy, but Jesus seems to have understood his role differently from others and suggested a very different way of looking at things, suggesting that the true eschatological perfection of the world was not one of conquest and lordship, but rather that it is every person's brithright to be free of sin and the fear of death. Most people then and now were not prepared to understand his enlightened perspective.
What, in you opinion proves or disproves Jesus existence?
It is impossible to prove or disprove, but someone had to start the tradition, and there's no reason to believe it wasn't Jesus. Moreover, there are aspects of Jesus's biography, such as his untimely death, that his later followers would have a hard time reconciling with the prevailing view of what the Messiah was supposed to be and do. That suggests that it really happened.
What did Jesus do?
He taught a different way of understanding things that on the one hand was in keeping with the later prophetic tradition, but on the other hand was still radical enough that it didn't sit well with a lot of people, and a lot of people found it hard to understand. He demonstrated universal love and enlightened mind and invited people to realize that they were much more than they thought they were. He was then killed by the Roman authorities, presumably for sedition, as being hailed as the true anointed king or "Son of God" (even if Jesus never meant that in an earthly sense) would have been seen as threatening to the current political order.
Does Jesus still have a meaning today?
Obviously he does have meaning to many people, in one way or another. I think his insights and teachings are still useful, although they are still hard to understand--even more so for people who are not familiar with his cultural context. He is not only a moral exemplar but also a model of the power to triumph over death and delusion.
Does Jesus have any meaning to you?
I view him in similar terms as Paul did, although I am not a Jew (but Paul said that in Christ there are no Jews or Gentiles). Jesus led the way for people in his world, to show them that delusion and death need not bind people, that there is liberation from the things that oppress us in this life. In Buddhist terms he is a Buddha whose teachings were colored by his particular cultural context. He had great insight and great compassion that led him to share that insight with others, even though it would mean his death in the end. But as long as he continues to inspire people and lead them towards liberation, he still lives on.
If you believed in Jesus do you think it would make any difference to your life?
I do believe in Jesus, and it has made a difference in my life. I am much more at peace now than when I was dismissing him out of hand, thanks to his mischaracterization at the hands of certain Christian groups. Unfortunately, the people who claim to most ardently follow him can sometimes be his worst evangelists. But Jesus is not the exclusive property of Christianity or any organized religion, so people need not feel as if they must adopt one particular doctrinal view of him.
Many Christians would tell me that I actually don't believe in Jesus because I don't believe what they believe about him, but I don't think that's for them to decide. "Christian" is not a label that Jesus would have recognized in any case, and people today put too much stock in it—and in who gets to carry it.
What meaning do you think Jesus has for Christians?
Christianity is such a big tent that it's probably impossible to answer that in brief. Many regard him as a divine lord and master in a literal sense, which I think is mistaken--his grandiose titles are honorifics given to a great teacher and savior, not a heavenly despot. Jesus never wanted to rule over people. Many see him as a kind of human sacrifice to remove people's guilt, but I would argue that's also a distortion that cheapens his accomplishments (and makes God look evil for demanding such a thing). Others see him as a liberator who is still delivering people from darkness and death, and that is a view I can get behind. And I think lots of people can agree that he exemplifies a radical kind of love and compassion, as well as the strength of the human spirit. Unfortunately, many people regard him as a unique, one-off thing, when that's not his teaching or that of Paul; on the contrary, all are invited to follow in his footsteps and be like him, doing exactly as he did. There is never any sense that the average person is not good or powerful enough to do just that.
