Does the Christian Tradition Explain the Significane of Jesus?
I think you should be more specific with this question. What part of the Christian Tradition? Which Christian Tradition? I would suspect that the significance of Jesus is not dependent on any or all traditions since the significance of Jesus is, on one level, totally person ... it comes from an encounter with Jesus on a personal level and is different for each person.
However, it is clear that the Christian tradition has had a powerful impact on history and the significant of Jesus in that history. Starting with Constantine Jesus Christianity moved from an "underground" religion to a state religion; Jesus moved from a personal relationship to a state relationship, and everything changed after that "moment." In the name of Jesus all kinds of things happened, some of them good, many of them not so good. This created the historical Christian Tradition and presented the significance of Jesus in a way much different than the early days of Christianity.
I'm not sure if this answers your question. Please update with additional information if it does not.
Yes the Christian tradition does explain the significance of Jesus. At Christmas we celebrate him as our Messiah (The King who we were waiting for). He was born in a manger to the virgin Mary, signifying that God is his father, because he had no earthly biological father.
At Easter he is our risen Savior (the perfect God/man). He was sacrificed on the cross for our sins. He suffered, died, and rose again on the third day. Then he walked among his disciples and spoke to them before he reascended into heaven to sit at the right hand of the father.
