2. Other than I AM of the Old Testament, no other founder of a religion is comparable to Jesus.
Quite incorrect. Looking aside, for a moment, that it is easily debatable that Jesus founded no religion, the parallels between he and the Buddha are manifold and obvious.
No authoritative spokesperson for any non Christian religion claims that its founder or reformer is comparable to Jesus in the way he manifested the authority of the Creator including his power over death itself.
Claptrap. This is posing the question in a dishonest light from the get-go. No 'authoritative' 'spokesperson'? And what is this based on? How does one know that such a person doesn't make the claim?
3. History affirms the Jesus of the Bible
Surely. But it affirms none of the miracles attributed to him, co-opted from earlier traditions.
Really? Did the Buddha claim he was God, was the Buddha's life and death prophesied? Was the Buddha born into royalty ( compared to Jesus' meager upbringing)? The dissimilarities are more obvious. What are the parrallels that should be obvious to me?
