Moroni’s statement of the essential nature of charity is stronger than the one his father used:
Moroni 7:47
47 But charity is the pure love of Christ, and it endureth forever; and whoso is found possessed of it at the last day, it shall be well with him.
For Mormon, it is a good thing. For Moroni it is an essential characteristic. Where Mormon tells us that “it shall be well” with one who has charity, Moroni tells us that “except ye have charity ye can in nowise be saved in the kingdom of God.” This fits with the contextual shift Moroni has for faith and hope as well, for Moroni places both of those in a similarly essential category, where Mormon’s use of the terms was preparatory.
