In an LDS Church News article published yesterday, the Church announced that Elder Jeffrey R. Holland dedicated Timor-Leste (East Timor) for missionary work last month. Timor-Leste has a homogeneously Christian population and no LDS presence. Investigatory trips from senior missionaries assigned to the Asia Area headquarters occurred several month ago in preparation for opening the country to missionary work. The first senior missionary couple was assigned on August 8th and has been primarily commissioned to begin LDS Charities activities in the country. There are no restrictions on religious freedom in Timor-Leste. Missionary work will commence in the Portuguese language under the Indonesia Jakarta Mission. Timor-Leste became independent from Indonesia in 2002 and currently has a population of 1.3 million.
