In the mid ‘90’s the Mormon Church changed the title to the front of the Book of Mormon. They changed it to say; “Book of Mormon, Another Testament of Jesus Christ”.
Now the book of Galatians says that if anyone or an angel tells us of another gospel, we are to reject it. And the verse in Hebrews says we have a better testament; that being Jesus Christ.
The Greek word for testament is: diatheôkeô. It means covenant or contract. Why then does the Church need a new covenant and of course this new covenant is nothing less than polygamy, another baptism, baptism for the dead, etc.?
D&C 132:1-66 tells them they will become gods if they abide this new law and covenant; for the sake of brevity we’re only including three of the verses.
Doctrine and Covenants 132:4, 37 & 62; 4-“For behold, I reveal unto you a new and an everlasting covenant; and if ye abide not that covenant, then are ye damned; for no one can reject this covenant and be permitted to enter into my glory: 37- Abraham received concubines, and they bore him children; and it was accounted unto him for righteousness.
62 -And if he have ten virgins given unto him by this law, he cannot commit adultery, for they belong to him, and they are given unto him; therefore is he justified.”
