Hat tips to Fez and barfo.
Again, unanswerable question because the premise is disputed. There may have been a Yeshua (Jesus in Greek) who taught and preached in the Middle East around 2000 years ago and had a following, although even that is unproven. But the rest? Divinity, virgin birth, miracles, rising from the dead?
And of course a lot of folks have claimed to be the second coming. How would YOU know it was the real dude?
And BTW, is it necessary for Jesus to return as a male?
But I'd guess I'd ask him/her if he/she every said anything about forced transvaginal ultrasounds and gay marriage being the fundamentals of his worship.
