Article Nine, Latter-day Revelation, Part 2 The ninth LDS Article of Faith says, “We believe all that God has revealed, all that He does now reveal, and we believe that He will yet reveal many great and important things pertaining to the Kingdom of God.” Doctrine & Covenants (D. &C.) 20:9 and 27:5 say that the Book of Mormon (B. of M.) contains the “fulness of the gospel.” If the B. of M. contains the “fulness of the everlasting gospel,” how can LDS prophets add more to it?
