“This is one of many occasions on which I have appeared to the peoples of the world...”
Really, I don’t have a problem with it. First off, we know that the promise of Abraham was that his seed would be a blessing among every nation. Further, Israel has been scattered time and time again throughout the earth, and not just the tribe of Judah, most of which is the story and history of the Bible.
There is a difference between Jesus reincarnating to/in various cultures and ages/religions, and the dispersing of peoples/Israelites.
It isn’t reincarnation, for our Lord Christ Jesus is Resurrected. He is very much alive today in a resurrected body as He was some 2000 years ago, except He has now ascended and is awaiting until His enemies are made a footstool unto His feet and the bringing of His bride to Him at the time chosen by the Father.
