That is not the OP question. The Christian response to anyone claiming to be the Jewish Messiah is obvious.
yes its aways been....jesus...anyone other than jesus comes is false....
but a man can come claiming to be "Yahushua"....an be not jesus, but just a man claiming to be jesus or yahushua to decieve the church..... he says "i am jesus"....but he is a liar to decieve the church
for we do not await a man ,,,,we await a God....
Behold jesus...
Rev 1
7 Look, he is coming with the clouds,[
b]
and every eye will see him,
even those who pierced him;
and all peoples on earth will mourn because of him.[
c]
So shall it be! Amen. 8 I am the Alpha and the Omega, says the Lord God, who is, and who was, and who is to come, the Almighty
14 The hair on his head was white like wool, as white as snow, and his eyes were like blazing fire. 15 His feet were like bronze glowing in a furnace, and his voice was like the sound of rushing waters. 16 In his right hand he held seven stars, and coming out of his mouth was a sharp, double-edged sword. His face was like the sun shining in all its brilliance.
17 When I saw him, I fell at his feet as though dead. Then he placed his right hand on me and said: Do not be afraid. I am the First and the Last. 18 I am the Living One; I was dead, and now look, I am alive for ever and ever! And I hold the keys of death and Hades.
