I have no idea what a 2000+ year old man would be like.
Then He must see the world of disarray He has thus far refused to intervene upon, for essentially all of recorded history. (I use the pronoun "He" in keeping with the paternalisitc culture that conceived "Him")
One wonders about the impact of such a being revealing themself to the public. Would He be written off as a loon, branded a charlatan or accepted as claimed? Would He be pestered to perform miracles, to demonstrate His divinity, or find cause to loose His wrath?
Perhaps it is best that such an individual remain anonymous.
but he isn't.
It's one of religions' believing "God", so I think, he's different, I am not a Christian, nor Catholicism, but there's the reason of the believers who believe him.
How disrespectful that would be to think of God as a slob, the bible states at John 4:24 that,"God is a Spirit, and those worshiping him must worship with spirit and truth." We are not like God in appreance but we do have his qualities such as love,justice,wisdom and power. Humans hove failed to use these wonderful qualities in the right way.
