According to www.ldscatalog.com, the Book of Mormon was recently translated in full in Guarani. Until now only selections of the Book of Mormon were translated into Guarani, which is an official language in Paraguay along with Spanish. Estimates of the number of Guarani speakers are put at around seven million.
The Church has grown rapidly in Paraguay for the past several years with membership climbing from 47,850 at the end of 2000 to 74,802 at the end of 2008. Congregations increased by 26 during this time period and for the past couple years we have seen very few new congregations created in Paraguay. Hopefully this indicates that many new congregations will be created in the coming year or two, especially considering that the most rapid growth in membership occurred very recently in 2006 and 2007.
