My Doubts About the Consensus of New Testament Scholars

I am entirely open to the possibility that it is objectively more probable than not that Jesus was a historical person.  However, when a scholar claims that he can be almost certain about specific things that Jesus said or did, I think that he is badly overestimating the weight that the evidence will bear.   As a result, when he urges me to trust the consensus of mainstream New Testament scholars like himself concerning the certainty of Jesus' historicity, I cannot help but wonder whether the weight the evidence will bear isn't being overestimated again.
