These are factual assertions; they are objectively either true or false.
If they are false, any faith which asserts them is a false faith.
If they are true, any faith which denies them is a false faith.
To assert that Jesus of Nazareth IS NOT God and IS NOT the Messiah promised by the Prophets is absolutely and identically to assert that Christianity is a false faith. (False by way of asserting falsehood.)
To assert that Jesus of Nazareth IS God and IS the Messiah promised by the Prophets is absolutely and identically to assert that Judaism is a false faith. (False by way of denying particular truths.)
To assert that Jesus of Nazareth both IS and IS NOT God, or both IS and IS NOT the Messiah promised by the Prophets is insane, incoherent, contradictory absurdity.
“All Christians believe (by definition) that Jesus of Nazareth was and is (a) God and (b) the Messiah promised by the Prophets.”
“These are factual assertions; they are objectively either true or false.”
How so? Isn’t it possible that they are subjectively either true or false?
Not a bad exercise in logic, up to a point. But you will have to agree that it is a two way street. Christianity has asserted that Judaism is either false, evil or at least, superfluous for 2,000 years.
Look, this ends up being pointless, because, in the end, almost every assertion of faith in a particular belief system leads to the conclusion that the other systems are wrong or inferior in some way. Where does that get you? Anger, hostility, division, resentment and worse.
I have tried in the years I’ve posted here to simply say that I respect people for their faith, in the sense
that they are trying to put real meaning into their lives, trying to improve the world, raise good children, live peacefully and so on. Why is it important to engage in a battle of the religions. I believe mine is the right one, so I do mine. If you believe differently, do yours. Everyone wins.
Have a nice day.
