How so? Without his teachings, he's just another carpenter. It's what he did and what he taught that make him notable.
RE: How so? Without his teachings, he’s just another carpenter.
I gather you are not a Christian. If he were simply a teacher, then he’s no different from any other teacher out there who ever taught people to observe the golden rule.
The fact that HE IS GOD makes His teaching authoritative. Other than that, we have no reason to observe all of His teachings.
Why not listen to Mohammad instead?
