What Abinadi taught

Noah's priests argued that they were righteous, and as proof, they quoted Isaiah's "how beautiful upon the mountains are the feet" passage (Mosiah 12). I think the point they were trying to make was that they believed themselves to be happy and rich and successful, so therefore they believed God must approve of them.

Abinadi was there to set them straight. As I pointed out in my previous post, he taught them that the system of worship they claimed to subscribe to was not going to save them. Only faith in the true God of Israel, un distracted by idols and false worship, could save them. 

And in Mosiah 13:35, Abinadi explains what a truly righteous and divinely approved person's life looks like from the outside: OPPRESSED AND AFFLICTED. What follows is an explanation of what and how we should worship, instead of the Law of Moses/ LDS Church. The Law/Church has its uses, but it is not the objective, nor the gatekeeper. Only Christ holds that position. Teaching or behaving as if anyone else or any institution holds that authority is idolatry, as Abinadi explains.
