Thought of the Day about Mormonism and People in America circa BC 545

2 Nephi 26:33; “…he denieth none that come unto him, black and white, bond and free, male and female; and he remembereth the heathen; and all are alike unto God, both Jew and Gentile.”

Were there any slaves, heathens, and white or black people in the Americas in 545 BC? If not then why is this verse in the Book of Mormon?

And why is this in the Book of Mormon anyway?

They’ve plagiarized the Apostle Paul 600 years before he even said a very similar thing in Galatians 3:28!
