In “seal[ing] up these records,” Moroni is not referring to any physical process that will bind the plates together, but rather to a spiritual sealing—an anointing to their divinely ordained purpose. This is the context for Moroni’s title page: “Written and sealed up, and hid up unto the Lord, that they might not be destroyed.” The sealing is so that “they might not be destroyed.” It is a protective sealing not a preventative sealing such as was placed on the vision of the brother of Jared. (See commentary accompanying Ether 5:1.)
