Yeah, but Protestants essentially affirm many of the same basic teachings as the older Catholic and Orthodox Churches (ie...The Holy Trinity)
Mormonism has stuff about Jewish Indians, the planet Kolob and brass plates. I don’t understand what the story is with it.
It's here if you want to read it.
Not Jewish indians. The peopling of the Americas, as taught by the LDS, were by those of the tribe of Ephraim and Menassah. Jews are from the tribe of Judah.
The brass plates were obtained in Jerusalem, and contained the writings from Adam to the time of the Prophet Jeremiah, all OT prophets. It is these plated that the people had to keep their faith, language, and Law of Moses intact. The plates that were given to Joseph Smith were patterned after the brass plates, and similarly contained the words of God as revealed to these ancient prophets and peoples.
Here is more information on the Brass Plates, not to be confused with the Gold Plates. The brass plates were of a much more ancient date.
