> I also doubt He was black, although some Rastafarians believe He was because it says so in Jeremiah 8:21.
That's an odd interpretation. The word in Hebrew stems from qadar, which does mean dark, but is often used to indicate mourning (https://biblehub.com/hebrew/6937.htm). And that follows the context of the verse: "Since my people are crushed, I am crushed; I mourn (qadarti), and horror grips me" (NIV). As far as I recall, the Bible never uses skin color to indicate race. It always goes by ancestry ("Abraham was the father of Isaac, Isaac the father of Jacob, . . . "). Speaking of which, it spends a great deal of time, across several books, to tell us that Jesus is Jewish. Most Jews I know of are fair skinned. Skin color doesn't mean any kind of superiority to me. I'm just talking about the accuracy of paintings.
> He certainly wasn't the fair-skinned, blue eyed, blond hair rock star depicted by some Christian denominations.
I've been a Christian all my life, and visited churches of many denominations. Most depictions show him with brown hair and brown eyes. I can't remember seeing any depiction with blond hair. Now blue eyes I have occasionally seen, but isn't it possible for any race to have any eye color?
