People refer to him in the past tense for qualities he already had. For instance...
"Jesus was white/black/middle eastern." ---Well, according to the Bible, he took his body with him to Heaven, so he would still be, not "was."
"Jesus was Jewish." ---Are we to assume he changed his faith? Bible says nothing about that.
People do this all the time when referring to qualities he should still have, according to their face.
Of course, I'm aware of the past tense grammar mechanic. But, I'm not referring to events; I'm referring to descriptions of him.
