I have just watched a "Stump the Rabbi" video about whether mashiach is actually a physical person. Rabbi Shloma Majeski states that mashiach can even be someone that has passed away, and especially if they did something in that generation for the redemption to come.
So after watching this I am wondering, doesn't he basically support the christian idea? I would like to know where exactly he stated in Tractate Sanhedrin if any of you know that mashiach can be someone that passed away. But couldn't a christian watch this and say that their idol is a "candidate".
Here is the video, it is about 5 minutes: https://youtu.be/ZQSYltoKbUY
